Version 2.0
**apitrace** consists of a set of tools to:
-* trace OpenGL, OpenGL ES, D3D9, D3D8, D3D7, and DDRAW APIs calls to a file;
+* trace OpenGL, OpenGL ES, Direct3D, and DirectDraw APIs calls to a file;
* retrace OpenGL and OpenGL ES calls from a file;
* visualize and edit trace files.
-Basic usage
-===========
+Obtaining **apitrace**
+======================
+To obtain apitrace either [download the latest
+binaries](https://github.com/apitrace/apitrace/downloads) for your platform if
+available, or follow the instructions in INSTALL.markdown to build it yourself.
+On 64bits Linux and Windows platforms you'll need apitrace binaries that match
+the architecture (32bits or 64bits) of the application being traced.
-Linux and Mac OS X
-------------------
+
+Basic usage
+===========
Run the application you want to trace as
- apitrace trace /path/to/application [args...]
+ apitrace trace --api API /path/to/application [args...]
and it will generate a trace named `application.trace` in the current
-directory. You can specify the written trace filename by setting the
-`TRACE_FILE` environment variable before running.
+directory. You can specify the written trace filename by passing the
+`--output` command line option.
+
+Problems while tracing (e.g, if the application uses calls/parameters
+unsupported by apitrace) will be reported via stderr output on Unices. On
+Windows you'll need to run
+[DebugView](http://technet.microsoft.com/en-us/sysinternals/bb896647) to view
+these messages.
+
+Follow the "Tracing manually" instructions below if you cannot obtain a trace.
View the trace with
- apitrace dump --color application.trace
+ apitrace dump application.trace
Replay an OpenGL trace with
Pass the `-sb` option to use a single buffered visual. Pass `--help` to
glretrace for more options.
-Start the GUI as
-
- qapitrace application.trace
-
-
-Windows
--------
-* Copy `opengl32.dll`, `d3d8.dll`, or `d3d9.dll` from build/wrappers directory
- to the directory with the application you want to trace.
+Basic GUI usage
+===============
-* Run the application.
-
-* View the trace with
+Start the GUI as
- \path\to\apitrace dump application.trace
+ qapitrace application.trace
-* Replay the trace with
+You can also tell the GUI to go directly to a specific call
- \path\to\glretrace application.trace
+ qapitrace application.trace 12345
Advanced command line usage
### Linux ###
+On 64 bits systems, you'll need to determine ether the application is 64 bits
+or 32 bits. This can be done by doing
+
+ file /path/to/application
+
+But beware of wrapper shell scripts -- what matters is the architecture of the
+main process.
+
Run the application you want to trace as
LD_PRELOAD=/path/to/apitrace/wrappers/glxtrace.so /path/to/application
gdb --ex 'set exec-wrapper env LD_PRELOAD=/path/to/glxtrace.so' --args /path/to/application
+### Android ###
+
+The following instructions should work at least for Android Ice Scream
+Sandwitch:
+
+For standalone applications the instructions above for Linux should
+work. To trace applications started from within the Android VM process
+(`app_process` aka zygote) you'll have to wrap this process and enable
+tracing dynamically for the application to be traced.
+
+- Wrapping the android main VM process:
+
+ In the Android root /init.rc add the `LD_PRELOAD` setting to zygote's
+ environment in the 'service zygote' section:
+
+ service zygote ...
+ setenv LD_PRELOAD /data/egltrace.so
+ ...
+
+ Note that ICS will overwrite the /init.rc during each boot with the
+ version in the recovery image. So you'll have to change the file in
+ your ICS source tree, rebuild and reflash the device.
+ Rebuilding/reflashing only the recovery image should be sufficient.
+
+- Copy egltrace.so to /data
+
+ On the host:
+
+ adb push /path/to/apitrace/build/wrappers/egltrace.so /data
+
+- Adjust file permissions to store the trace file:
+
+ By default egltrace.so will store the trace in
+ `/data/app_process.trace`. For this to work for applications running
+ with a uid other than 0, you have to allow writes to the `/data`
+ directory on the device:
+
+ chmod 0777 /data
+
+- Enable tracing for a specific process name:
+
+ To trace for example the Settings application:
+
+ setprop debug.apitrace.procname com.android.settings
+
+ In general this name will match what `ps` reports.
+
+- Start the application:
+
+ If the application was already running, for example due to ICS's way
+ of pre-starting the apps, you might have to kill the application
+ first:
+
+ kill <pid of app>
+
+ Launch the application for example from the application menu.
+
### Mac OS X ###
Run the application you want to trace as
`DYLD_FORCE_FLAT_NAMESPACE=1` which breaks most applications. See the `dyld` man
page for more details about these environment flags.
+### Windows ###
+
+When tracing third-party applications, you can identify the target
+application's main executable, either by:
+
+* right clicking on the application's icon in the _Start Menu_, choose
+ _Properties_, and see the _Target_ field;
+
+* or by starting the application, run Windows Task Manager (taskmgr.exe), right
+ click on the application name in the _Applications_ tab, choose _Go To Process_,
+ note the highlighted _Image Name_, and search it on `C:\Program Files` or
+ `C:\Program Files (x86)`.
+
+On 64 bits Windows, you'll need to determine ether the application is a 64 bits
+or 32 bits. 32 bits applications will have a `*32` suffix in the _Image Name_
+column of the _Processes_ tab of _Windows Task Manager_ window.
+
+Copy the appropriate `opengl32.dll`, `d3d8.dll`, or `d3d9.dll` from the
+wrappers directory to the directory with the application you want to trace.
+Then run the application as usual.
+
+You can specify the written trace filename by setting the `TRACE_FILE`
+environment variable before running.
-Emitting annotations to the trace from GL applications
-------------------------------------------------------
-You can emit string and frame annotations through the
+Emitting annotations to the trace
+---------------------------------
+
+From OpenGL applications you can embed annotations in the trace file through the
[`GL_GREMEDY_string_marker`](http://www.opengl.org/registry/specs/GREMEDY/string_marker.txt)
and
[`GL_GREMEDY_frame_terminator`](http://www.opengl.org/registry/specs/GREMEDY/frame_terminator.txt)
This has the added advantage of working equally well with gDEBugger.
+From OpenGL ES applications you can embed annotations in the trace file through the
+[`GL_EXT_debug_marker`](http://www.khronos.org/registry/gles/extensions/EXT/EXT_debug_marker.txt)
+extension.
+
+
+For Direct3D applications you can follow the same procedure used for
+[instrumenting an application for PIX](http://technet.microsoft.com/en-us/query/ee417250)
+
+
Dump GL state at a particular call
----------------------------------
| ffmpeg -r 30 -f image2pipe -vcodec ppm -i pipe: -vcodec mpeg4 -y output.mp4
+Trimming a trace
+----------------
+
+You can make a smaller trace by doing:
+
+ apitrace trim --callset 100-1000 -o trimed.trace applicated.trace
+
+If you need precise control over which calls to trim you can specify the
+individual call numbers a plaintext file, as described in the 'Call sets'
+section above.
+
+
+Profiling a trace
+-----------------
+
+You can perform gpu and cpu profiling with the command line options:
+
+ * `-pgpu` record gpu times for frames and draw calls.
+
+ * `-pcpu` record cpu times for frames and draw calls.
+
+ * `-ppd` record pixels drawn for each draw call.
+
+The results from this can then be read by hand or analysed with a script.
+
+`scripts/profileshader.py` will read the profile results and format them into a
+table which displays profiling results per shader.
+
+For example, to record all profiling data and utilise the per shader script:
+
+ ./glretrace -pgpu -pcpu -ppd foo.trace | ./scripts/profileshader.py
+
+
Advanced usage for OpenGL implementors
======================================
* obtain a trace
-* obtain reference snapshots, by doing:
+* obtain reference snapshots, by doing on a reference system:
- mkdir /path/to/snapshots/
+ mkdir /path/to/reference/snapshots/
glretrace -s /path/to/reference/snapshots/ application.trace
- on reference system.
-
* prune the snapshots which are not interesting
* to do a regression test, do:
Alternatively, for a HTML summary, use `apitrace diff-images`:
- glretrace -s /path/to/current/snapshots/ application.trace
- apitrace diff-images --output summary.html /path/to/reference/snapshots/ /path/to/current/snapshots/
+ glretrace -s /path/to/test/snapshots/ application.trace
+ apitrace diff-images --output summary.html /path/to/reference/snapshots/ /path/to/test/snapshots/
Automated git-bisection
This can be achieved with retracediff.py script, which invokes glretrace with
different environments, allowing to choose the desired GL driver by
-manipulating variables such as `LD_LIBRARY_PATH` or `LIBGL_DRIVERS_DIR`.
+manipulating variables such as `LD_LIBRARY_PATH`, `LIBGL_DRIVERS_DIR`, or
+`TRACE_LIBGL`.
-For example:
+For example, on Linux:
./scripts/retracediff.py \
--ref-env LD_LIBRARY_PATH=/path/to/reference/GL/implementation \
- -r ./glretrace \
+ --retrace /path/to/glretrace \
--diff-prefix=/path/to/output/diffs \
application.trace

-Things To Do
-============
-
-(in no particular order)
-
-
-Tracing
--------
-
-* Allow clamping to a GL version or a number of extensions.
-
-* Put (de)compression in a separate thread.
-
-* Trace TSCs
-
-* Trace window sizes somehow
-
-* Allow to distinguish between the calls really done by the program, vs the
- fakes one necessary to retrace correctly.
-
-* Start tracing on demand (e.g., key-press, or by frame no), emitting calls
- that recreate all current state.
-
-* Add option to include call stack frames in the trace.
-
-* Trace the internal GL calls done by GLU on Mac OS X & Windows.
-
-
-Retracing
----------
-
-* Use visuals that best match those used in the trace; specially auto
- detect single/double buffer visuals.
-
-* Respect multiple context sharing of the traces.
-
-* Support multiple threads
-
-* Leverage `ARB_debug_output` where available.
-
-* D3D support.
-
-
-GUI
----
-
-* Timeline view.
-
-* Visualize meshes in draw commands.
-
-* Breakpointing and step-by-step debugging.
-
-
-CLI
----
-
-* Add retrace Replay all the calls in a trace
-* Add trim Trim a trace by including only the specified calls/frames
-* Add dump-state Output the OpenGL state in JSON format
-* Add dump-images Create image files for each frame/drawing operation of a trace
-
-* Add some common command-line options:
-
- Most commands acting on a trace accept the following common options:
-
- --calls=[RANGE] Operate only on calls with index numbers within
- the specified range.
-
- --frames=[RANGE] Operate only on frames with index numbers within
- the specified range.
-
- --functions=[REGEXP] Operate only on function calls which have a
- name that matches the given regular expression.
-
- A [RANGE] can be any of the following:
-
- Example Description
- ------- -----------
- 4 A single number specifying a single call or frame.
-
- 10-20 Two numbers separated by '-' (FIRST-LAST) specifying a
- range of consecutive calls/frames from FIRST to LAST. If
- either of FIRST or LAST is omitted, the first or last
- call/frame index in the trace will be used.
-
- 1-100/5 Either of the above range specifications followed by '/'
- and a number (INTERVAL). This specifies the inclusion of
- only each INTERVAL call/frame within the range. For
- example, 1-100/5 species frame 1, frame 5, frame 10,
- ... up to frame 100.
-
- 4,10-20/2 A comma separated list of any of the above range
- specifications, specifying the union of the ranges.
-
-* Add some retrace-specific options (-b, -db, -sb, -v)
-
-* Add some trime-specific options (--every={draw,framebuffer,frame})
-
-* Accept a filename for --calls or --functions (to use the same calls
- or functions as present in a trace dump).
-
-* Add an "apitrace bisect" for trimming down a trace based on user
- input at each stage.
-
-* Add an "apitrace git-bisect-helper" for calling from git-bisect.
-
-
-Other
------
-
-* Side-by-side trace diffing; either as a separate tool on or the GUI.
-
-* Ability to extract just a single frame from a trace, and all previous calls
- that contributed to it:
-
- * via a state tracker (i.e., knowledge of how calls affect the state);
-
- * or by leveragine retrace, dumping the calls to emit all state at beginning
- of the frame.
-

+# Android CMake toolchain file, for use with the Android NDK r5-r8
+# Requires cmake 2.6.3 or newer (2.8.5 or newer is recommended).
+# See home page: http://code.google.com/p/android-cmake/
+#
+# The file is mantained by the OpenCV project. And also can be found at
+# http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.cmake
+#
+# Usage Linux:
+# $ export ANDROID_NDK=/absolute/path/to/the/android-ndk
+# $ mkdir build && cd build
+# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
+# $ make -j8
+#
+# Usage Linux (using standalone toolchain):
+# $ export ANDROID_STANDALONE_TOOLCHAIN=/absolute/path/to/android-toolchain
+# $ mkdir build && cd build
+# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
+# $ make -j8
+#
+# Usage Windows:
+# You need native port of make to build your project.
+# Android NDK r7 (or newer) already has make.exe on board.
+# For older NDK you have to install it separately.
+# For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm
+#
+# $ SET ANDROID_NDK=C:\absolute\path\to\the\android-ndk
+# $ mkdir build && cd build
+# $ cmake.exe -G"MinGW Makefiles"
+# -DCMAKE_TOOLCHAIN_FILE=path\to\the\android.toolchain.cmake
+# -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows\bin\make.exe" ..
+# $ "%ANDROID_NDK%\prebuilt\windows\bin\make.exe"
+#
+#
+# Options (can be set as cmake parameters: -D<option_name>=<value>):
+# ANDROID_NDK=/opt/android-ndk - path to the NDK root.
+# Can be set as environment variable. Can be set only at first cmake run.
+#
+# ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
+# standalone toolchain. This option is not used if full NDK is found
+# (ignored if ANDROID_NDK is set).
+# Can be set as environment variable. Can be set only at first cmake run.
+#
+# ANDROID_ABI=armeabi-v7a - specifies the target Application Binary
+# Interface (ABI). This option nearly matches to the APP_ABI variable
+# used by ndk-build tool from Android NDK.
+#
+# Possible targets are:
+# "armeabi" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "armeabi-v7a" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "armeabi-v7a with NEON" - same as armeabi-v7a, but
+# sets NEON as floating-point unit
+# "armeabi-v7a with VFPV3" - same as armeabi-v7a, but
+# sets VFPV3 as floating-point unit (has 32 registers instead of 16).
+# "armeabi-v6 with VFP" - tuned for ARMv6 processors having VFP.
+# "x86" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "mips" - matches to the NDK ABI with the same name
+# (not testes on real devices)
+#
+# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
+# Option is read-only when standalone toolchain used.
+#
+# ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions
+# instead of Thumb-1. Is not available for "x86" (inapplicable) and
+# "armeabi-v6 with VFP" (forced) ABIs.
+#
+# ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker
+# errors even if they are not used.
+#
+# ANDROID_SO_UNDEFINED=OFF - set true to allow undefined symbols in shared
+# libraries. Automatically turned on for NDK r5x and r6x due to GLESv2
+# problems.
+#
+# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
+# files. See additional details below.
+#
+# ANDROID_SET_OBSOLETE_VARIABLES=ON - it set, then toolchain defines some
+# obsolete variables which were set by previous versions of this file for
+# backward compatibility.
+#
+#
+# What?:
+# android-cmake toolchain searches for NDK/toolchain in the following order:
+# ANDROID_NDK - cmake parameter
+# ANDROID_NDK - environment variable
+# ANDROID_STANDALONE_TOOLCHAIN - cmake parameter
+# ANDROID_STANDALONE_TOOLCHAIN - environment variable
+# ANDROID_NDK - default locations
+# ANDROID_STANDALONE_TOOLCHAIN - default locations
+#
+# Make sure to do the following in your scripts:
+# SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}" )
+# SET( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}" )
+# The flags will be prepopulated with critical flags, so don't loose them.
+# Also be aware that toolchain also sets configuration-specific compiler
+# flags and linker flags.
+#
+# ANDROID and BUILD_ANDROID will be set to true, you may test any of these
+# variables to make necessary Android-specific configuration changes.
+#
+# Also ARMEABI or ARMEABI_V7A or X86 will be set true, mutually exclusive.
+# NEON option will be set true if VFP is set to NEON.
+#
+# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android
+# libraries will be installed.
+# Default is ${CMAKE_SOURCE_DIR}, and the android libs will always be
+# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME}
+# (depending on the target ABI). This is convenient for Android packaging.

+ * khronos_uint8_t unsigned 8 bit
+ * khronos_int16_t signed 16 bit
+ * khronos_uint16_t unsigned 16 bit

+ * khronos_uint32_t unsigned 32 bit
+ * khronos_int64_t signed 64 bit
+ * khronos_uint64_t unsigned 64 bit
+ * khronos_intptr_t signed same number of bits as a pointer
+ * khronos_uintptr_t unsigned same number of bits as a pointer
+ * khronos_ssize_t signed size
+ * khronos_usize_t unsigned size
+ * khronos_float_t signed 32 bit floating point
+ * khronos_time_ns_t unsigned 64 bit time in nanoseconds
+ * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ * nanoseconds
+ * khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ * khronos_boolean_enum_t enumerated boolean type. This should
+ * only be used as a base type when a client API's boolean type is
+ * an enum. Client APIs which use an integer or other type for
+ * booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>

+ This file describes how to build and install less using
+the "configure" script. This only works on Unix systems.
+To install on other systems, read the README file.
+
+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+ so UPARROW/DOWNARROW can be used to retrieve them from the :e command.
+
+* Now works correctly on Windows when using a scrolling terminal
+ window (buffer larger than display window).
+
+* On Windows, now restores the console screen on exit.
+ Use -X to get the old behavior.
+
+* Fixed bug on Windows when CAPS-LOCK or NUM-LOCK is pressed.
+
+* Fixed bug on Windows when piping output of an interactive program.
+
+* Fixed bug in tags file processing when tags file has DOS-style
+ line terminators (CR/LF).
+
+* Fixed compilation problem on OS/2.
+
+======================================================================
+
+
+ Major changes between "less" versions 321 and 330
+
+* Now supports filenames containing spaces (in double quotes).
+ New option -" can be used to change the quoting characters.
+
+* In filename completion, a slash is appended to a directory name.
+ If the environment variable LESSSEPARATOR is set, the value of
+ that variable, rather than a slash, is appended.
+
+* LeftArrow and RightArrow are same as ESC-[ and ESC-].
+
+* Added commands ESC-( and ESC-), same as ESC-[ and ESC-].
+
+* A "quit" command defined in a lesskey file may now have an "extra"
+ string, which is used to return an exit code from less when it quits.
+
+* New environment variables LESSMETACHARS and LESSMETAESCAPE provide
+ more control over how less interfaces to the shell.
+
+* Ported to Microsoft Visual C compiler for Windows.
+
+* Ported to DJGPP compiler for MS-DOS.
+
+* Bug fixes.
+
+======================================================================
+
+
+ Major changes between "less" versions 291 and 321
+
+* Command line at bottom of screen now scrolls, so it can be longer
+ than the screen width.
+
+* New commands ESC-] and ESC-[ scroll the display horizontally.
+
+* New command ESC-SPACE scrolls forward a full screen, even if it
+ hits end-of-file.
+
+* Alternate modifiers for search commands: ^N is same as !,
+ ^F is same as @, and ^E is same as *.
+
+* New modifier for search commands: ^K means highlight the matches
+ currently on-screen, but don't move to the first match.
+
+* New modifier for search commands: ^R means don't use regular
+ expressions in the search.
+
+* Environment variable LESSKEY gives name of default lesskey file.
+
+* Environment variable LESSSECURE will force less to run in
+ "secure" mode.
+
+* Command line argument "--" signals that the rest of the arguments
+ are files (not option flags).
+
+* Help file (less.hlp) is no longer installed. Help text is now
+ embedded in the less executable itself.
+
+* Added -Ph to change the prompt for the help text.
+ Added -Ps to change the default short prompt (same as plain -P).
+
+* Ported to the Borland C compiler for MS-DOS.
+
+* Ported to Windows 95 & Windows NT.
+
+* Ported to OS-9.
+
+* Ported to GNU Hurd.
+
+======================================================================
+
+
+ Major changes between "less" versions 290 and 291
+
+* Less environment variables can be specified in lesskey files.
+
+* Fixed MS-DOS build.
+
+======================================================================
+
+
+ Major changes between "less" versions 278 and 290
+
+* Accepts GNU-style options "--help" and "--version".
+
+* OS/2 version looks for less.ini in $HOME before $INIT and $PATH.
+
+* Bug fixes
+
+======================================================================
+
+
+ Major changes between "less" versions 252 and 278
+
+* A LESSOPEN preprocessor may now pipe the converted file data to less,
+ rather than writing it to a temporary file.
+
+* Search pattern highlighting has been fixed. It now highlights
+ reliably, even if a string is split across two screen lines,
+ contains TABs, etc.
+
+* The -F flag (which suppress search highlighting) has been changed
+ to -G. A new flag, -g, changes search highlighting to highlight
+ only the string found by the last search command, instead of all
+ strings which match the last search command.
+
+* New flag -I acts like -i, but ignores case even if the search
+ pattern contains uppercase letters.
+
+* Less now checks for the environment variable VISUAL before EDITOR.
+
+* Ported to OS/2.
+
+======================================================================
+
+
+ Major changes between "less" versions 237 and 252
+
+* Changes in line-editing keys:
+ The literal key is now ^V or ^A rather than \ (backslash).
+ Filename completion commands (TAB and ^L) are disabled
+ when typing a search pattern.
+
+* Line-editing command keys can be redefined using lesskey.
+
+* Lesskey with no input file defaults to $HOME/.lesskey
+ rather than standard input.

+
+* Help file less.hlp is now installed by default in /usr/local/share
+ rather than /usr/local/lib.
+
+
+======================================================================
+
+
+ Major changes between "less" versions 170 and 237
+
+* By popular demand, text which matches the current search pattern
+ is highlighted. New -F flag disables this feature.
+
+* Henry Spencer's regexp.c is now included, for systems which do not
+ have a regular expression library.
+ regexp.c is Copyright (c) 1986 by University of Toronto.
+
+* New line-editing keys, including command history (arrow keys) and
+ filename completion (TAB).
+
+* Input preprocessor allows modification of input files (e.g. uncompress)
+ via LESSOPEN/LESSCLOSE environment variables.
+
+* New -X flag disables sending termcap "ti" and "te" (initialize and
+ deinitialize) strings to the terminal.
+
+* Changing -i from within less now correctly affects a subsequent
+ repeated search.
+
+* Searching for underlined or overstruck text now works when the -u
+ flag is in effect, rather than the -i flag.
+
+* Use setlocale (LANG and LC_CTYPE environment variables) to determine
+ the character set if LESSCHARSET/LESSCHARDEF are not set.
+
+* The default format for displaying binary characters is now standout
+ (reverse video) rather than blinking. This can still be changed by
+ setting the LESSBINFMT environment variable.
+
+* Use autoconf installation technology.
+
+* Ported to MS-DOS.
+
+ ********************************
+ Things that may surprise you
+ ********************************
+
+* When you enter text at the bottom of the screen (search string,
+ filename, etc.), some keys act different than previously.
+ Specifically, \ (backslash), ESC, TAB, BACKTAB, and control-L
+ now have line editing functions.
+
+* Some previous unofficial versions of less were able to display
+ compressed files. The new LESSOPEN/LESSCLOSE feature now provides
+ this functionality in a different way.
+
+* Some previous unofficial versions of less provided a -Z flag to
+ set the number of lines of text to retain between full screen scrolls.
+ The -z-n flag (that is, -z with a negative number) provides this
+ functionality.
+
+
+======================================================================
+
+
+ Major changes between "less" versions 123 and 170
+
+* New option -j allows target lines to be positioned anywhere on screen.
+
+* New option -S truncates displayed line at the screen width,
+ rather than wrapping onto the next line.
+
+* New option -y limits amount of forward scroll.
+
+* New option -T specifies a "tags" file.
+
+* Non-printable, non-control characters are displayed in octal.
+ Such characters, as well as control characters, are displayed
+ in blinking mode.
+
+* New command -+ sets an option to its default.
+* New command -- sets an option to the opposite of its default.
+
+* Lesskey file may have a string appended to a key's action,
+ which acts as though typed in after the command.
+
+* New commands ESC-^F and ESC-^B match arbitrary types of brackets.
+
+* New command F monitors a growing file (like "tail -f").
+
+* New command | pipes a section of the input file into a shell command.
+
+* New command :x directly jumps to a file in the command line list.
+
+* Search commands have been enhanced and reorganized:
+ n Repeat search, same direction.
+ N Repeat search, opposite direction.
+ ESC-/ Search forward thru file boundaries
+ ESC-? Search backward thru file boundaries
+ ESC-n Repeat search thru file boundaries, same direction.
+ ESC-N Repeat search thru file boundaries, opposite direction.
+ Special character * causes search to search thru file boundaries.
+ Special character @ causes search to begin at start/end of file list.
+
+* Examining a new file adds it to the command line list.
+ A list of files, or an expression which matches more than one file,
+ may be examined; all of them are added to the command line list.
+
+* Environment variables LESSCHARSET and LESSCHARDEF can define
+ a non-ASCII character set.
+
+* Partial support for MSDOS, including options -R for repainting screen
+ on quit, -v/-V to select video mode, and -W to change window size.
+
+
+======================================================================
+
+
+ Major changes between "less" versions 97 and 123
+
+* New option (-N) causes line numbers to be displayed in the
+ text of the file (like vi "set nu").
+
+* New option (-?) prints help message immediately.
+
+* New option (-r) displays "raw" control characters, without
+ mapping them to ^X notation.
+
+* New option (-f) forces less to open non-regular files
+ (directories, etc).
+
+* New option (-k) can be used to specify lesskey files by name.
+
+* New option (-y) can be used to set a forward scroll limit
+ (like -h sets a backward scroll limit).
+
+* File marks (set by the m command) are now preserved when a new
+ file is edited. The ' command can thus be used to switch files.
+
+* New command ESC-/ searches all files (on the command line)
+ for a pattern.
+
+* New command ESC-n repeats previous search, spanning files.
+
+* The N command has been changed to repeat the previous search
+ in the reverse direction. The old N command is still available
+ via :n.
+
+* New command ESC-N repeats previous search in the reverse
+ direction and spanning files.
+
+* 8 bit characters are now supported. A new option (-g) can be
+ used to strip off the eighth bit (the previous behavior).
+
+* Options which take a following string (like -t) may now
+ optionally have a space between the option letter and the string.
+
+* Six new commands { } ( ) [ and ] can be used to match
+ brackets of specific types, similar to vi % command.
+
+* New commands z and w move forward/backward one window and
+ simultaneously set the window size.
+
+* Prompt string expansion now has %L for line number of the last
+ line in the file, and %E for the name of the editor.
+ Also, % escapes which refer to a line (b=bottom, t=top, etc.)
+ can use j for the jump target line.
+
+* New environment variable LESSEDIT can be used to tailor the
+ command string passed to the editor by the v command.
+
+* Examining a file which was previously examined will return
+ to the same position in the file.
+
+* A "%" is expanded to the current filename and a "#" to the
+ previous filename, in both shell commands and the E command.
+ (Previously % worked only in shell commands and # worked
+ only in the E command.)
+
+* New command ":ta" is equivalent to "-t".
+
+* New command "s" is equivalent to "-l".
+
+* The - command may be followed by "+X" to revert to the default
+ for option X, or "-X" to get the opposite of the default.
+
+* Lesskey files may now include characters after the action as
+ extra input to be parsed after the action; for example:
+ "toggle-option X" to toggle a specific option X.

+ Less, version 444
+
+ This is the distribution of less, version 444, released 09 Jun 2011.
+ This program is part of the GNU project (http://www.gnu.org).
+
+ This program is free software. You may redistribute it and/or
+ modify it under the terms of either:
+
+ 1. The GNU General Public License, as published by the Free
+ Software Foundation; either version 3, or (at your option) any

+ or
+ 2. The Less License, in the file LICENSE.
+
+ Please report any problems to bug-less@gnu.org or markn@greenwoodsoftware.com.
+ See http://www.greenwoodsoftware.com/less for the latest info.
+
+=========================================================================
+
+This is the distribution of "less", a paginator similar to "more" or "pg".
+
+The formatted manual page is in less.man.
+The manual page nroff source is in less.nro.
+Major changes made since the last posted version are in NEWS.
+
+=======================================================================
+INSTALLATION (Unix systems only):
+
+1. Move the distributed source to its own directory and unpack it,
+ if you have not already done so.
+
+2. Type "sh configure".
+ This will generate a Makefile and a defines.h.
+ Warning: if you have a GNU sed, make sure it is version 2.05 or later.
+
+ The file INSTALL describes the usage of the configure program in
+ general. In addition, these options to configure are supported:
+
+ --with-editor=program
+ Specifies the default editor program used by the "v" command.
+ The default is "vi".
+
+ --with-regex=lib
+ Specifies the regular expression library used by less for pattern
+ matching. The default is "auto", which means the configure program
+ finds a regular expression library automatically. Other values are:
+ posix Use the POSIX-compatible regcomp.
+ pcre Use the PCRE library.
+ regcmp Use the regcmp library.
+ re_comp Use the re_comp library.
+ regcomp Use the V8-compatible regcomp.
+ regcomp-local Use Henry Spencer's V8-compatible regcomp
+ (source is supplied with less).
+ --with-secure
+ Builds a "secure" version of less, with some features disabled
+ to prevent users from viewing other files, accessing shell
+ commands, etc.
+
+
+3. It is a good idea to look over the generated Makefile and defines.h
+ and make sure they look ok. If you know of any peculiarities of
+ your system that configure might not have detected, you may fix the
+ Makefile now. Take particular notice of the list of "terminal"
+ libraries in the LIBS definition in the Makefile; these may need
+ to be edited. The terminal libraries will be some subset of
+ -lncurses -lcurses -ltermcap -ltermlib
+
+ If you wish, you may edit defines.h to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page "less.nro" and the help page "less.hlp"
+ to remove the descriptions of the features which you are removing.
+ If you edit less.hlp, you should run "make -f Makefile.aut help.c".
+
+4. Type "make" and watch the fun.
+
+5. If the make succeeds, it will generate the programs "less",
+ "lesskey" and "lessecho" in your current directory. Test the
+ generated programs.
+
+6. When satisfied that it works, if you wish to install it
+ in a public place, type "make install".
+
+ The default install destinations are:
+ Executables (less, lesskey, lessecho) in /usr/local/bin
+ Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
+ If you want to install any of these files elsewhere, define
+ bindir and/or mandir to the appropriate directories.
+
+If you have any problems building or running "less", suggestions,
+complaints, etc., you may mail to the author at markn@greenwoodsoftware.com.
+
+Note to hackers: comments noting possible improvements are enclosed
+in double curly brackets {{ like this }}.
+
+(Note that the above note was originally written at a time when
+"hackers" most commonly meant "enthusiastic and dedicated computer
+programmers", not "persons who attempt to circumvent computer security".)
+
+
+
+=======================================================================
+INSTALLATION (MS-DOS systems only,
+ with Microsoft C, Borland C, or DJGPP)
+
+1. Move the distributed source to its own directory.
+ Depending on your compiler, you may need to convert the source
+ to have CR-LF rather than LF as line terminators.
+
+2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
+ If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
+ If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
+
+3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
+ are correct. CC should be the name of your C compiler and
+ LIBDIR should be the directory where the C libraries reside (for
+ Microsoft C only). If these definitions need to be changed, you can
+ either modify the definitions directly in MAKEFILE, or set your
+ environment variables CC and/or LIBDIR to override the definitions
+ in MAKEFILE.
+
+4. If you wish, you may edit DEFINES.DS to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page LESS.MAN and the help page HELP.C
+ to remove the descriptions of the features which you are removing.
+
+5. Run your "make" program and watch the fun.
+ If your "make" requires a flag to import environment variables,
+ you should use that flag.
+ If your compiler runs out of memory, try running "make -n >cmds.bat"
+ and then run cmds.bat.
+
+6. If the make succeeds, it will generate the programs "LESS.EXE" and
+ "LESSKEY.EXE" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, you may wish to install LESS.EXE and
+ LESSKEY.EXE in a directory which is included in your PATH.
+
+
+
+=======================================================================
+INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only,
+ with Borland C or Microsoft Visual C++)
+
+1. Move the distributed source to its own directory.
+
+2. If you are using Borland C, rename Makefile.wnb to Makefile.
+ If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.wn to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+ "lesskey.exe" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, if you wish to install it
+ in a public place, type "make install".
+ See step 6 of the Unix installation instructions for details
+ on how to change the default installation directories.
+
+
+
+=======================================================================
+INSTALLATION (OS/2 systems only,
+ with EMX C)
+
+1. Move the distributed source to its own directory.
+
+2. Rename Makefile.o2e to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.o2 to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "make" and watch the fun.
+
+6. If the make succeeds, it will generate the programs "less.exe" and
+ "lesskey.exe" in your current directory. Test the generated programs.
+
+7. Make sure you have the emx runtime installed. You need the emx DLLs
+ emx.dll and emxlibcs.dll and also the termcap database, termcap.dat.
+ Make sure you have termcap.dat either in the default location or
+ somewhere in a directory listed in the PATH or INIT environment
+ variables.
+
+8. When satisfied that it works, you may wish to install less.exe,
+ lesskey.exe and scrsize.exe in a directory which is included in
+ your PATH. scrsize.exe is required only if you use a terminal
+ emulator such as xterm or rxvt.
+
+
+
+=======================================================================
+INSTALLATION (OS-9 systems only,
+ with Microware C or Ultra C)
+
+1. Move the distributed source to its own directory.
+
+2. If you are using Microware C, rename Makefile.o9c to Makefile.
+ If you are using Ultra C, rename Makefile.o9u to Makefile.
+
+3. Check the Makefile to make sure the definitions look ok.
+
+4. If you wish, you may edit defines.o9 to remove some optional features.
+ If you choose not to include some features in your version, you may
+ wish to edit the manual page less.man and the help page help.c
+ to remove the descriptions of the features which you are removing.
+
+5. Type "dmake" and watch the fun.
+ The standard OS-9 "make" will probably not work. If you don't
+ have dmake, you can get a copy from os9archive.rtsi.com.
+
+6. If the make succeeds, it will generate the programs "less" and
+ "lesskey" in your current directory. Test the generated programs.
+
+7. When satisfied that it works, if you wish to install it
+ in a public place, type "dmake install".
+ See step 6 of the Unix installation instructions for details
+ on how to change the default installation directories.

+ *
+ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
+ *
+ * Make a .less file.
+ * If no input file is specified, standard input is used.
+ * If no output file is specified, $HOME/.less is used.
+ *
+ * The .less file is used to specify (to "less") user-defined
+ * key bindings. Basically any sequence of 1 to MAX_CMDLEN
+ * keystrokes may be bound to an existing less function.
+ *
+ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
+ *
+ * The input file is an ascii file consisting of a
+ * sequence of lines of the form:
+ * string <whitespace> action [chars] <newline>
+ *
+ * "string" is a sequence of command characters which form
+ * the new user-defined command. The command
+ * characters may be:
+ * 1. The actual character itself.
+ * 2. A character preceded by ^ to specify a
+ * control character (e.g. ^X means control-X).
+ * 3. A backslash followed by one to three octal digits
+ * to specify a character by its octal value.
+ * 4. A backslash followed by b, e, n, r or t
+ * to specify \b, ESC, \n, \r or \t, respectively.
+ * 5. Any character (other than those mentioned above) preceded
+ * by a \ to specify the character itself (characters which
+ * must be preceded by \ include ^, \, and whitespace.
+ * "action" is the name of a "less" action, from the table below.
+ * "chars" is an optional sequence of characters which is treated
+ * as keyboard input after the command is executed.
+ *
+ * Blank lines and lines which start with # are ignored,
+ * except for the special control lines:
+ * #command Signals the beginning of the command
+ * keys section.
+ * #line-edit Signals the beginning of the line-editing
+ * keys section.
+ * #env Signals the beginning of the environment
+ * variable section.
+ * #stop Stops command parsing in less;
+ * causes all default keys to be disabled.
+ *
+ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
+ *
+ * The output file is a non-ascii file, consisting of a header,
+ * one or more sections, and a trailer.
+ * Each section begins with a section header, a section length word
+ * and the section data. Normally there are three sections:
+ * CMD_SECTION Definition of command keys.
+ * EDIT_SECTION Definition of editing keys.
+ * END_SECTION A special section header, with no
+ * length word or section data.
+ *
+ * Section data consists of zero or more byte sequences of the form:
+ * string <0> <action>
+ * or
+ * string <0> <action|A_EXTRA> chars <0>
+ *
+ * "string" is the command string.
+ * "<0>" is one null byte.
+ * "<action>" is one byte containing the action code (the A_xxx value).
+ * If action is ORed with A_EXTRA, the action byte is followed
+ * by the null-terminated "chars" string.

+ * wouldn't work if we couldn't get to the start of the file; e.g.
+ * if input is a long pipe).
+ *
+ * So we use the function add_lnum to cache line numbers.
+ * We try to be very clever and keep only the more interesting
+ * line numbers when we run out of space in our table. A line
+ * number is more interesting than another when it is far from
+ * other line numbers. For example, we'd rather keep lines
+ * 100,200,300 than 100,101,300. 200 is more interesting than
+ * 101 because 101 can be derived very cheaply from 100, while
+ * 200 is more expensive to derive from 100.
+ *
+ * The function currline() returns the line number of a given
+ * position in the file. As a side effect, it calls add_lnum
+ * to cache the line number. Therefore currline is occasionally
+ * called to make sure we cache line numbers often enough.

-Changes since the last public release (1.5.2):
-
- More -Wshadow fixes for older gcc compilers. Older gcc versions apparently
- check formal parameters names in function declarations (as well as
- definitions) to see if they match a name in the global namespace.
- Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the
- old VisualC++ preprocessor.
- Turned on interlace handling in png_read_png().
- Fixed gcc pendantic warnings.
- Handle longjmp in Cygwin.
- Fixed png_get_current_row_number() in the interlaced case.
- Cleaned up ALPHA flags and transformations.
- Implemented expansion to 16 bits.
- Fixed mistake in the descriptions of user read_transform and write_transform
- function prototypes in the manual. The row_info struct is png_row_infop.
- Corrected png_get_current_row_number documentation
- Fixed the read/write row callback documentation.
- This documents the current behavior, where the callback is called after
- every row with information pertaining to the next row.
- Fixed scripts/makefile.vcwin32
- Updated contrib/pngsuite/README to add the word "modify".
- Define PNG_ALLOCATED and other attributes to blank when _MSC_VER<1300.
- ifdef out mask arrays in pngread.c when interlacing is not supported.
- Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak
- and in contrib/pngminim/*/makefile, eg., on SunOS 5.10, and removed "strip"
- from the makefiles.
- Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
- to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill)
- Don't include standard header files in png.h while building the symbol table,
- to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro).

+
+Changes since the last public release (1.5.8):
+
+ Rebuilt configure scripts in the tar distributions.
+ Removed two unused definitions from scripts/pnglibconf.h.prebuilt
+ Removed some unused arrays (with #ifdef) from png_read_push_finish_row().
+ Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h
+ Fixed CVE-2011-3026 buffer overrun bug. Deal more correctly with the test
+ on iCCP chunk length. Also removed spurious casts that may hide problems

Version 1.5.1beta02 [January 14, 2011]
Fixed a bug in handling of interlaced images (bero at arklinux.org).
pngvalid contains tests of transforms, which tests are currently disabled
because they are incompletely tested. gray_to_rgb was failing to expand
the bit depth for smaller bit depth images; this seems to be a long

to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro).
Version 1.5.2 [March 31, 2011]
+ No changes.
+
+Version 1.5.3beta01 [April 1, 2011]
+ Re-initialize the zlib compressor before compressing non-IDAT chunks.
+ Added API functions (png_set_text_compression_level() and four others) to
+ set parameters for zlib compression of non-IDAT chunks.
+
+Version 1.5.3beta02 [April 3, 2011]
+ Updated scripts/symbols.def with new API functions.
+ Only compile the new zlib re-initializing code when text or iCCP is
+ supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro.
+ Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03).
+ Optimize the zlib CMF byte in non-IDAT compressed chunks
+
+Version 1.5.3beta03 [April 16, 2011]
+ Fixed gcc -ansi -pedantic compile. A strict ANSI system does not have
+ snprintf, and the "__STRICT_ANSI__" detects that condition more reliably
+ than __STDC__ (John Bowler).
+ Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells
+ the compiler that a user supplied callback (the error handler) does not
+ return, yet there is no guarantee in practice that the application code
+ will correctly implement the error handler because the compiler only
+ issues a warning if there is a mistake (John Bowler).
+ Removed the no-longer-used PNG_DEPSTRUCT macro.
+ Updated the zlib version to 1.2.5 in the VStudio project.
+ Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in
+ pngwutil.c (John Bowler).
+ Fixed bug with stripping the filler or alpha channel when writing, that
+ was introduced in libpng-1.5.2beta01 (bug report by Andrew Church).
+
+Version 1.5.3beta04 [April 27, 2011]
+ Updated pngtest.png with the new zlib CMF optimization.
+ Cleaned up conditional compilation code and of background/gamma handling
+ Internal changes only except a new option to avoid compiling the
+ png_build_grayscale_palette API (which is not used at all internally.)
+ The main change is to move the transform tests (READ_TRANSFORMS,
+ WRITE_TRANSFORMS) up one level to the caller of the APIs. This avoids
+ calls to spurious functions if all transforms are disabled and slightly
+ simplifies those functions. Pngvalid modified to handle this.
+ A minor change is to stop the strip_16 and expand_16 interfaces from
+ disabling each other; this allows the future alpha premultiplication
+ code to use 16-bit intermediate values while still producing 8-bit output.
+ png_do_background and png_do_gamma have been simplified to take a single
+ pointer to the png_struct rather than pointers to every item required
+ from the png_struct. This makes no practical difference to the internal
+ code.
+ A serious bug in the pngvalid internal routine 'standard_display_init' has
+ been fixed - this failed to initialize the red channel and accidentally
+ initialized the alpha channel twice.
+ Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to
+ avoid a possible clash with the png_jmpbuf macro on some platforms.
+
+Version 1.5.3beta05 [May 6, 2011]
+ Added the "_POSIX_SOURCE" feature test macro to ensure libpng sees the
+ correct API. _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and
+ pngvalid.c to ensure that POSIX conformant systems disable non-POSIX APIs.
+ Removed png_snprintf and added formatted warning messages. This change adds
+ internal APIs to allow png_warning messages to have parameters without
+ requiring the host OS to implement snprintf. As a side effect the
+ dependency of the tIME-supporting RFC1132 code on stdio is removed and
+ PNG_NO_WARNINGS does actually work now.
+ Pass "" instead of '\0' to png_default_error() in png_err(). This mistake
+ was introduced in libpng-1.2.20beta01. This fixes CVE-2011-2691.
+ Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make the zlib "CMF" byte
+ optimization configureable.
+ IDAT compression failed if preceded by a compressed text chunk (bug
+ introduced in libpng-1.5.3beta01-02). This was because the attempt to
+ reset the zlib stream in png_write_IDAT happened after the first IDAT
+ chunk had been deflated - much too late. In this change internal
+ functions were added to claim/release the z_stream and, hopefully, make
+ the code more robust. Also deflateEnd checking is added - previously
+ libpng would ignore an error at the end of the stream.
+
+Version 1.5.3beta06 [May 8, 2011]
+ Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt
+ Implemented premultiplied alpha support: png_set_alpha_mode API
+
+Version 1.5.3beta07 [May 11, 2011]
+ Added expand_16 support to the high level interface.
+ Added named value and 'flag' gamma support to png_set_gamma. Made a minor
+ change from the previous (unreleased) ABI/API to hide the exact value used
+ for Macs - it's not a good idea to embed this in the ABI!
+ Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and PNG_AFTER_IDAT
+ from pngpriv.h to png.h because they must be visible to applications
+ that call png_set_unknown_chunks().
+ Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
+ before IDAT.
+
+Version 1.5.3beta08 [May 16, 2011]
+ Improved "pngvalid --speed" to exclude more of pngvalid from the time.
+ Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt
+ The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
+ parameters are supplied by the caller), while in the absence of cHRM
+ sRGB/Rec 709 values are still used. This introduced a divide-by-zero
+ bug in png_handle_cHRM().
+ The bKGD chunk no longer overwrites the background value set by
+ png_set_background(), allowing the latter to be used before the file
+ header is read. It never performed any useful function to override
+ the default anyway.
+ Added memory overwrite and palette image checks to pngvalid.c
+ Previously palette image code was poorly checked. Since the transformation
+ code has a special palette path in most cases this was a severe weakness.
+ Minor cleanup and some extra checking in pngrutil.c and pngrtran.c. When
+ expanding an indexed image, always expand to RGBA if transparency is
+ present.
+
+Version 1.5.3beta09 [May 17, 2011]
+ Reversed earlier 1.5.3 change of transformation order; move png_expand_16
+ back where it was. The change doesn't work because it requires 16-bit
+ gamma tables when the code only generates 8-bit ones. This fails
+ silently; the libpng code just doesn't do any gamma correction. Moving
+ the tests back leaves the old, inaccurate, 8-bit gamma calculations, but
+ these are clearly better than none!
+
+Version 1.5.3beta10 [May 20, 2011]
+
+ png_set_background() and png_expand_16() did not work together correctly.
+ This problem is present in 1.5.2; if png_set_background is called with
+ need_expand false and the matching 16 bit color libpng erroneously just
+ treats it as an 8-bit color because of where png_do_expand_16 is in the
+ transform list. This simple fix reduces the supplied colour to 8-bits,
+ so it gets smashed, but this is better than the current behavior.
+ Added tests for expand16, more fixes for palette image tests to pngvalid.
+ Corrects the code for palette image tests and disables attempts to
+ validate palette colors.
+
+Version 1.5.3rc01 [June 3, 2011]
+ No changes.
+
+Version 1.5.3rc02 [June 8, 2011]
+ Fixed uninitialized memory read in png_format_buffer() (Bug report by
+ Frank Busse, CVE-2011-2501, related to CVE-2004-0421).
+
+Version 1.5.3beta11 [June 11, 2011]
+ Fixed png_handle_sCAL which is broken in 1.5. This fixes CVE 2011-2692.
+ Added sCAL to pngtest.png
+ Revised documentation about png_set_user_limits() to say that it also affects
+ png writing.
+ Revised handling of png_set_user_limits() so that it can increase the
+ limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only
+ reduce it.
+ Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
+ wrong (high by one) 25% of the time. Dividing by 257 with rounding is
+ wrong in 128 out of 65536 cases. Getting the right answer all the time
+ without division is easy.
+ Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro.
+ Added projects/owatcom, an IDE project for OpenWatcom to replace
+ scripts/makefile.watcom. This project works with OpenWatcom 1.9. The
+ IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
+ The project is configurable, unlike the Visual Studio project, so long
+ as the developer has an awk.
+ Changed png_set_gAMA to limit the gamma value range so that the inverse
+ of the stored value cannot overflow the fixed point representation,
+ and changed other things OpenWatcom warns about.
+ Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows
+ pngvalid to build when ALPHA_MODE is not supported, which is required if
+ it is to build on libpng 1.4.
+ Removed string/memory macros that are no longer used and are not
+ necessarily fully supportable, particularly png_strncpy and png_snprintf.
+ Added log option to pngvalid.c and attempted to improve gamma messages.
+
+Version 1.5.3 [omitted]
+ People found the presence of a beta release following an rc release
+ to be confusing; therefore we bump the version to libpng-1.5.4beta01
+ and there will be no libpng-1.5.3 release.
+
+Version 1.5.4beta01 [June 14, 2011]
+ Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED
+ to get the same (inaccurate) output as libpng-1.5.2 and earlier.
+ Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE
+ outside of an unknown-chunk block in png.h because they are also
+ needed for other uses.
+
+Version 1.5.4beta02 [June 14, 2011]
+ Fixed and clarified LEGACY 16-to-8 scaling code.
+ Added png_set_chop_16() API, to match inaccurate results from previous
+ libpng versions.
+ Removed the ACCURATE and LEGACY options (they are no longer useable)
+ Use the old scaling method for background if png_set_chop_16() was
+ called.
+ Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED
+
+Version 1.5.4beta03 [June 15, 2011]
+ Fixed a problem in png_do_expand_palette() exposed by optimization in
+ 1.5.3beta06
+ Also removed a spurious and confusing "trans" member ("trans") from png_info.
+ The palette expand optimization prevented expansion to an intermediate RGBA
+ form if tRNS was present but alpha was marked to be stripped; this exposed
+ a check for tRNS in png_do_expand_palette() which is inconsistent with the
+ code elsewhere in libpng.
+ Correction to the expand_16 code; removed extra instance of
+ png_set_scale_16_to_8 from pngpriv.h
+
+Version 1.5.4beta04 [June 16, 2011]
+ Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c
+ Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms.
+ Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is
+ not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built.
+ Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8
+
+Version 1.5.4beta05 [June 16, 2011]
+ Renamed png_set_strip_16() to png_set_scale_16() and renamed
+ png_set_chop_16() to png_set_strip(16) in an attempt to minimize the
+ behavior changes between libpng14 and libpng15.
+
+Version 1.5.4beta06 [June 18, 2011]
+ Fixed new bug that was causing both strip_16 and scale_16 to be applied.
+
+Version 1.5.4beta07 [June 19, 2011]
+ Fixed pngvalid, simplified macros, added checking for 0 in sCAL.
+ The ACCURATE scale macro is no longer defined in 1.5 - call the
+ png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined
+ if the png_strip_16_to_8 API is present. png_check_fp_number now
+ maintains some state so that positive, negative and zero values are
+ identified. sCAL uses these to be strictly spec conformant.
+
+Version 1.5.4beta08 [June 23, 2011]
+ Fixed pngvalid if ACCURATE_SCALE is defined.
+ Updated scripts/pnglibconf.h.prebuilt.
+
+Version 1.5.4rc01 [June 30, 2011]
+ Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400.
+
+Version 1.5.4 [July 7, 2011]
+ No changes.
+
+Version 1.5.5beta01 [July 13, 2011]
+ Fixed some typos and made other minor changes in the manual.
+ Updated contrib/pngminus/makefile.std (Samuli Souminen)
+
+Version 1.5.5beta02 [July 14, 2011]
+ Revised Makefile.am and Makefile.in to look in the right directory for
+ pnglibconf.h.prebuilt
+
+Version 1.5.5beta03 [July 27, 2011]
+ Enabled compilation with g++ compiler. This compiler does not recognize
+ the file extension, so it always compiles with C++ rules. Made minor
+ changes to pngrutil.c to cast results where C++ expects it but C does not.
+ Minor editing of libpng.3 and libpng-manual.txt.
+
+Version 1.5.5beta04 [July 29, 2011]
+ Revised CMakeLists.txt (Clifford Yapp)
+ Updated commentary about the png_rgb_to_gray() default coefficients
+ in the manual and in pngrtran.c
+
+Version 1.5.5beta05 [August 17, 2011]
+ Prevent unexpected API exports from non-libpng DLLs on Windows. The "_DLL"
+ is removed from the test of whether a DLL is being built (this erroneously
+ caused the libpng APIs to be marked as DLL exports in static builds under
+ Microsoft Visual Studio). Almost all of the libpng building configuration
+ is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in
+ pngconf.h, though, so that it is colocated with the import definition (it
+ is no longer used anywhere in the installed headers). The VStudio project
+ definitions have been cleaned up: "_USRDLL" has been removed from the
+ static library builds (this was incorrect), and PNG_USE_DLL has been added
+ to pngvalid to test the functionality (pngtest does not supply it,
+ deliberately). The spurious "_EXPORTS" has been removed from the
+ libpng build (all these errors were a result of copy/paste between project
+ configurations.)
+ Added new types and internal functions for CIE RGB end point handling to
+ pngpriv.h (functions yet to be implemented).
+
+Version 1.5.5beta06 [August 26, 2011]
+ Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt
+ (Clifford Yap)
+ Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler):
+ The rgb_to_gray code had errors when combined with gamma correction.
+ Some pixels were treated as true grey when they weren't and such pixels
+ and true grey ones were not gamma corrected (the original value of the
+ red component was used instead). APIs to get and set cHRM using color
+ space end points have been added and the rgb_to_gray code that defaults
+ based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT
+ VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected.
+ A considerable number of tests has been added to pngvalid for the
+ rgb_to_gray transform.
+ Arithmetic errors in rgb_to_gray whereby the calculated gray value was
+ truncated to the bit depth rather than rounded have been fixed except in
+ the 8-bit non-gamma-corrected case (where consistency seems more important
+ than correctness.) The code still has considerable inaccuracies in the
+ 8-bit case because 8-bit linear arithmetic is used.
+
+Version 1.5.5beta07 [September 7, 2011]
+ Added "$(ARCH)" option to makefile.darwin
+ Added SunOS support to configure.ac and Makefile.am
+ Changed png_chunk_benign_error() to png_warning() in png.c, in
+ png_XYZ_from_xy_checked().
+
+Version 1.5.5beta08 [September 10, 2011]
+ Fixed 64-bit compilation errors (gcc). The errors fixed relate
+ to conditions where types that are 32 bits in the GCC 32-bit
+ world (uLong and png_size_t) become 64 bits in the 64-bit
+ world. This produces potential truncation errors which the
+ compiler correctly flags.
+ Relocated new HAVE_SOLARIS_LD definition in configure.ac
+ Constant changes for 64-bit compatibility (removal of L suffixes). The
+ 16-bit cases still use "L" as we don't have a 16-bit test system.
+
+Version 1.5.5rc01 [September 15, 2011]
+ Removed "L" suffixes in pngpriv.h
+
+Version 1.5.5 [September 22, 2011]
+ No changes.
+
+Version 1.5.6beta01 [September 22, 2011]
+ Fixed some 64-bit type conversion warnings in pngrtran.c
+ Moved row_info from png_struct to a local variable.
+ The various interlace mask arrays have been made into arrays of
+ bytes and made PNG_CONST and static (previously some arrays were
+ marked PNG_CONST and some weren't).
+ Additional checks have been added to the transform code to validate the
+ pixel depths after the transforms on both read and write.
+ Removed some redundant code from pngwrite.c, in png_destroy_write_struct().
+ Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4].
+ This removes the need to allocate temporary strings for chunk names on
+ the stack in the read/write code. Unknown chunk handling still uses the
+ string form because this is exposed in the API.
+
+Version 1.5.6beta02 [September 26, 2011]
+ Added a note in the manual the png_read_update_info() must be called only
+ once with a particular info_ptr.
+ Fixed a typo in the definition of the new PNG_STRING_FROM_CHUNK(s,c) macro.
+
+Version 1.5.6beta03 [September 28, 2011]
+ Revised test-pngtest.sh to report FAIL when pngtest fails.
+ Added "--strict" option to pngtest, to report FAIL when the failure is
+ only because the resulting valid files are different.
+ Revised CMakeLists.txt to work with mingw and removed some material from
+ CMakeLists.txt that is no longer useful in libpng-1.5.
+
+Version 1.5.6beta04 [October 5, 2011]
+ Fixed typo in Makefile.in and Makefile.am ("-M Wl" should be "-M -Wl")."
+
+Version 1.5.6beta05 [October 12, 2011]
+ Speed up png_combine_row() for interlaced images. This reduces the generality
+ of the code, allowing it to be optimized for Adam7 interlace. The masks
+ passed to png_combine_row() are now generated internally, avoiding
+ some code duplication and localizing the interlace handling somewhat.
+ Align png_struct::row_buf - previously it was always unaligned, caused by
+ a bug in the code that attempted to align it; the code needs to subtract
+ one from the pointer to take account of the filter byte prepended to
+ each row.
+ Optimized png_combine_row() when rows are aligned. This gains a small
+ percentage for 16-bit and 32-bit pixels in the typical case where the
+ output row buffers are appropriately aligned. The optimization was not
+ previously possible because the png_struct buffer was always misaligned.
+ Fixed bug in png_write_chunk_header() debug print, introduced in 1.5.6beta01.
+
+Version 1.5.6beta06 [October 17, 2011]
+ Removed two redundant tests for unitialized row.
+ Fixed a relatively harmless memory overwrite in compressed text writing
+ with a 1 byte zlib buffer.
+ Add ability to call png_read_update_info multiple times to pngvalid.c.
+ Fixes for multiple calls to png_read_update_info. These fixes attend to
+ most of the errors revealed in pngvalid, however doing the gamma work
+ twice results in inaccuracies that can't be easily fixed. There is now
+ a warning in the code if this is going to happen.
+ Turned on multiple png_read_update_info in pngvalid transform tests.
+ Prevent libpng from overwriting unused bits at the end of the image when
+ it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
+ overwrite the partial byte at the end of each row if the row width was not
+ an exact multiple of 8 bits and the image is not interlaced.
+
+Version 1.5.6beta07 [October 21, 2011]
+ Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
+ (Mans Rullgard).
+
+Version 1.5.6rc01 [October 26, 2011]
+ Changed misleading "Missing PLTE before cHRM" warning to "Out of place cHRM"
+
+Version 1.5.6rc02 [October 27, 2011]
+ Added LSR() macro to defend against buggy compilers that evaluate non-taken
+ code branches and complain about out-of-range shifts.
+
+Version 1.5.6rc03 [October 28, 2011]
+ Renamed the LSR() macro to PNG_LSR() and added PNG_LSL() macro.
+ Fixed compiler warnings with Intel and MSYS compilers. The logical shift
+ fix for Microsoft Visual C is required by other compilers, so this
+ enables that fix for all compilers when using compile-time constants.
+ Under MSYS 'byte' is a name declared in a system header file, so we
+ changed the name of a local variable to avoid the warnings that result.
+ Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/*/pngusr.h
+
+Version 1.5.6 [November 3, 2011]
+ No changes.
+
+Version 1.5.7beta01 [November 4, 2011]
+ Added support for ARM processor (Mans Rullgard)
+ Fixed bug in pngvalid on early allocation failure; fixed type cast in
+ pngmem.c; pngvalid would attempt to call png_error() if the allocation
+ of a png_struct or png_info failed. This would probably have led to a
+ crash. The pngmem.c implementation of png_malloc() included a cast
+ to png_size_t which would fail on large allocations on 16-bit systems.
+ Fix for the preprocessor of the Intel C compiler. The preprocessor
+ splits adjacent @ signs with a space; this changes the concatentation
+ token from @-@-@ to PNG_JOIN; that should work with all compiler
+ preprocessors.
+ Paeth filter speed improvements from work by Siarhei Siamashka. This
+ changes the 'Paeth' reconstruction function to improve the GCC code
+ generation on x86. The changes are only part of the suggested ones;
+ just the changes that definitely improve speed and remain simple.
+ The changes also slightly increase the clarity of the code.
+
+Version 1.5.7beta02 [November 11, 2011]
+ Check compression_type parameter in png_get_iCCP and remove spurious
+ casts. The compression_type parameter is always assigned to, so must
+ be non-NULL. The cast of the profile length potentially truncated the
+ value unnecessarily on a 16-bit int system, so the cast of the (byte)
+ compression type to (int) is specified by ANSI-C anyway.
+ Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left
+ the sBIT fields in the test pixel as 0, which resulted in a floating
+ point division by zero which was irrelevant but causes systems where
+ FP exceptions cause a crash. Added code to pngvalid to turn on FP
+ exceptions if the appropriate glibc support is there to ensure this is
+ tested in the future.
+ Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the
+ new PNG_JOIN macro.
+ Added versioning to pnglibconf.h comments.
+ Simplified read/write API initial version; basic read/write tested on
+ a variety of images, limited documentation (in the header file.)
+ Installed more accurate linear to sRGB conversion tables. The slightly
+ modified tables reduce the number of 16-bit values that
+ convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used
+ to generate the tables is now in a contrib/sRGBtables sub-directory.
+
+Version 1.5.7beta03 [November 17, 2011]
+ Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c
+ Added run-time detection of NEON support.
+ Added contrib/libtests; includes simplified API test and timing test and
+ a color conversion utility for rapid checking of failed 'pngstest' results.
+ Multiple transform bug fixes plus a work-round for double gamma correction.
+ libpng does not support more than one transform that requires linear data
+ at once - if this is tried typically the results is double gamma
+ correction. Since the simplified APIs can need rgb to gray combined with
+ a compose operation it is necessary to do one of these outside the main
+ libpng transform code. This check-in also contains fixes to various bugs
+ in the simplified APIs themselves and to some bugs in compose and rgb to
+ gray (on palette) itself.
+ Fixes for C++ compilation using g++ When libpng source is compiled
+ using g++. The compiler imposes C++ rules on the C source; thus it
+ is desireable to make the source work with either C or C++ rules
+ without throwing away useful error information. This change adds
+ png_voidcast to allow C semantic (void*) cases or the corresponding
+ C++ static_cast operation, as appropriate.
+ Added --noexecstack to assembler file compilation. GCC does not set
+ this on assembler compilation, even though it does on C compilation.
+ This creates security issues if assembler code is enabled; the
+ work-around is to set it by default in the flags for $(CCAS)
+ Work around compilers that don't support declaration of const data. Some
+ compilers fault 'extern const' data declarations (because the data is
+ not initialized); this turns on const-ness only for compilers where
+ this is known to work.
+
+Version 1.5.7beta04 [November 17, 2011]
+ Since the gcc driver does not recognize the --noexecstack flag, we must
+ use the -Wa prefix to have it passed through to the assembler.
+ Also removed a duplicate setting of this flag.
+ Added files that were omitted from the libpng-1.5.7beta03 zip distribution.
+
+Version 1.5.7beta05 [November 25, 2011]
+ Removed "zTXt" from warning in generic chunk decompression function.
+ Validate time settings passed to pngset() and png_convert_to_rfc1123()
+ (Frank Busse).
+ Added MINGW support to CMakeLists.txt
+ Reject invalid compression flag or method when reading the iTXt chunk.
+ Backed out 'simplified' API changes. The API seems too complex and there
+ is a lack of consensus or enthusiasm for the proposals. The API also
+ reveals significant bugs inside libpng (double gamma correction and the
+ known bug of being unable to retrieve a corrected palette). It seems
+ better to wait until the bugs, at least, are corrected.
+ Moved pngvalid.c into contrib/libtests
+ Rebuilt Makefile.in, configure, etc., with autoconf-2.68
+
+Version 1.5.7rc01 [December 1, 2011]
+ Replaced an "#if" with "#ifdef" in pngrtran.c
+ Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else)
+
+Version 1.5.7rc02 [December 5, 2011]
+ Revised project files and contrib/pngvalid/pngvalid.c to account for
+ the relocation of pngvalid into contrib/libtests.
+ Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400,
+ as in libpng-1.5.4.
+ Put CRLF line endings in the owatcom project files.
+
+Version 1.5.7rc03 [December 7, 2011]
+ Updated CMakeLists.txt to account for the relocation of pngvalid.c
+
+Version 1.5.7 [December 15, 2011]
+ Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings
+ reported by earlier versions.
+
+Version 1.5.8beta01 [January 15, 2011]
+ Removed '#include config.h"' from contrib/libtests/pngvalid.c. It's not
+ needed and causes trouble for VPATH building.
+ Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper
+ location in configure.ac (Gilles Espinasse).
+ Fix bug in pngerror.c: some long warnings were being improperly truncated
+ (CVE-2011-3464, bug introduced in libpng-1.5.3beta05).
+
+Version 1.5.8rc01 [January 21, 2012]
+ No changes.
+
+Version 1.5.8rc02 [January 25, 2012]
+ Fixed Min/GW uninstall to remove libpng.dll.a
+ Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt
+
+Version 1.5.8 [February 1, 2012]
+ No changes.
+
+Version 1.5.9beta01 [February 3, 2012]
+ Rebuilt configure scripts in the tar distributions.
+
+Version 1.5.9beta02 [February 16, 2012]
+ Removed two unused definitions from scripts/pnglibconf.h.prebuilt
+ Removed some unused arrays (with #ifdef) from png_read_push_finish_row().
+ Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h
+
+Version 1.5.9rc01 [February 17, 2012]
+ Fixed CVE-2011-3026 buffer overrun bug. Deal more correctly with the test
+ on iCCP chunk length. Also removed spurious casts that may hide problems
+ on 16-bit systems.
+
+Version 1.5.9 [February 18, 2012]
+ No changes.

-
-I. Introduction
-
-This file describes how to use and modify the PNG reference library
-(known as libpng) for your own use. There are five sections to this
-file: introduction, structures, reading, writing, and modification and
-configuration notes for various special platforms. In addition to this
-file, example.c is a good starting point for using the library, as
-it is heavily commented and should include everything most people
-will need. We assume that libpng is already installed; see the
-INSTALL file for instructions on how to install libpng.
-
-For examples of libpng usage, see the files "example.c", "pngtest.c",
-and the files in the "contrib" directory, all of which are included in
-the libpng distribution.
-
-Libpng was written as a companion to the PNG specification, as a way
-of reducing the amount of time and effort it takes to support the PNG
-file format in application programs.
-
-The PNG specification (second edition), November 2003, is available as
-a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at
-<http://www.w3.org/TR/2003/REC-PNG-20031110/
-The W3C and ISO documents have identical technical content.
-
-The PNG-1.2 specification is available at
-<http://www.libpng.org/pub/png/documents/>. It is technically equivalent
-to the PNG specification (second edition) but has some additional material.
-
-The PNG-1.0 specification is available
-as RFC 2083 <http://www.libpng.org/pub/png/documents/> and as a
-W3C Recommendation <http://www.w3.org/TR/REC.png.html>.
-
-Some additional chunks are described in the special-purpose public chunks
-documents at <http://www.libpng.org/pub/png/documents/>.
-
-Other information
-about PNG, and the latest version of libpng, can be found at the PNG home
-page, <http://www.libpng.org/pub/png/>.
-
-Most users will not have to modify the library significantly; advanced
-users may want to modify it more. All attempts were made to make it as
-complete as possible, while keeping the code easy to understand.
-Currently, this library only supports C. Support for other languages
-is being considered.
-
-Libpng has been designed to handle multiple sessions at one time,
-to be easily modifiable, to be portable to the vast majority of
-machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy
-to use. The ultimate goal of libpng is to promote the acceptance of
-the PNG file format in whatever way possible. While there is still
-work to be done (see the TODO file), libpng should cover the
-majority of the needs of its users.
-
-Libpng uses zlib for its compression and decompression of PNG files.
-Further information about zlib, and the latest version of zlib, can
-be found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
-The zlib compression utility is a general purpose utility that is
-useful for more than PNG files, and can be used without libpng.
-See the documentation delivered with zlib for more details.
-You can usually find the source files for the zlib utility wherever you
-find the libpng source files.
-
-Libpng is thread safe, provided the threads are using different
-instances of the structures. Each thread should have its own
-png_struct and png_info instances, and thus its own image.
-Libpng does not protect itself against two threads using the
-same instance of a structure.
-
-II. Structures
-
-There are two main structures that are important to libpng, png_struct
-and png_info. The first, png_struct, is an internal structure that
-will not, for the most part, be used by a user except as the first
-variable passed to every libpng function call.
-
-The png_info structure is designed to provide information about the
-PNG file. At one time, the fields of png_info were intended to be
-directly accessible to the user. However, this tended to cause problems
-with applications using dynamically loaded libraries, and as a result
-a set of interface functions for png_info (the png_get_*() and png_set_*()
-functions) was developed. The fields of png_info are still available for
-older applications, but it is suggested that applications use the new
-interfaces if at all possible.
-
-Applications that do make direct access to the members of png_struct (except
-for png_ptr->jmpbuf) must be recompiled whenever the library is updated,
-and applications that make direct access to the members of png_info must
-be recompiled if they were compiled or loaded with libpng version 1.0.6,
-in which the members were in a different order. In version 1.0.7, the
-members of the png_info structure reverted to the old order, as they were
-in versions 0.97c through 1.0.5. Starting with version 2.0.0, both
-structures are going to be hidden, and the contents of the structures will
-only be accessible through the png_get/png_set functions.
-
-The png.h header file is an invaluable reference for programming with libpng.
-And while I'm on the topic, make sure you include the libpng header file:
-
-#include <png.h>
-
-III. Reading
-
-We'll now walk you through the possible functions to call when reading
-in a PNG file sequentially, briefly explaining the syntax and purpose
-of each one. See example.c and png.h for more detail. While
-progressive reading is covered in the next section, you will still
-need some of the functions discussed in this section to read a PNG
-file.
-
-Setup
-
-You will want to do the I/O initialization(*) before you get into libpng,
-so if it doesn't work, you don't have much to undo. Of course, you
-will also want to insure that you are, in fact, dealing with a PNG
-file. Libpng provides a simple check to see if a file is a PNG file.
-To use it, pass in the first 1 to 8 bytes of the file to the function
-png_sig_cmp(), and it will return 0 (false) if the bytes match the
-corresponding bytes of the PNG signature, or nonzero (true) otherwise.
-Of course, the more bytes you pass in, the greater the accuracy of the
-prediction.
-
-If you are intending to keep the file pointer open for use in libpng,
-you must ensure you don't read more than 8 bytes from the beginning
-of the file, and you also have to make a call to png_set_sig_bytes_read()
-with the number of bytes you read from the beginning. Libpng will
-then only check the bytes (if any) that your program didn't read.
-
-(*): If you are not using the standard I/O functions, you will need
-to replace them with custom functions. See the discussion under
-Customizing libpng.
-
-
- FILE *fp = fopen(file_name, "rb");
- if (!fp)
- {
- return (ERROR);
- }
- fread(header, 1, number, fp);
- is_png = !png_sig_cmp(header, 0, number);
- if (!is_png)
- {
- return (NOT_PNG);
- }
-
-
-Next, png_struct and png_info need to be allocated and initialized. In
-order to ensure that the size of these structures is correct even with a
-dynamically linked libpng, there are functions to initialize and
-allocate the structures. We also pass the library version, optional
-pointers to error handling functions, and a pointer to a data struct for
-use by the error functions, if necessary (the pointer and functions can
-be NULL if the default error handlers are to be used). See the section
-on Changes to Libpng below regarding the old initialization functions.
-The structure allocation functions quietly return NULL if they fail to
-create the structure, so your application should check for that.
-
- png_structp png_ptr = png_create_read_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_read_struct(&png_ptr,
- (png_infopp)NULL, (png_infopp)NULL);
- return (ERROR);
- }
-
- png_infop end_info = png_create_info_struct(png_ptr);
- if (!end_info)
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_read_struct_2() instead of png_create_read_struct():
-
- png_structp png_ptr = png_create_read_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-The error handling routines passed to png_create_read_struct()
-and the memory alloc/free routines passed to png_create_struct_2()
-are only necessary if you are not using the libpng supplied error
-handling and memory alloc/free functions.
-
-When libpng encounters an error, it expects to longjmp back
-to your routine. Therefore, you will need to call setjmp and pass
-your png_jmpbuf(png_ptr). If you read the file from different
-routines, you will need to update the jmpbuf field every time you enter
-a new routine that will call a png_*() function.
-
-See your documentation of setjmp/longjmp for your compiler for more
-information on setjmp/longjmp. See the discussion on libpng error
-handling in the Customizing Libpng section below for more information
-on the libpng error handling. If an error occurs, and libpng longjmp's
-back to your setjmp, you will want to call png_destroy_read_struct() to
-free any memory.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
- fclose(fp);
- return (ERROR);
- }
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the input code. The default for libpng is to
-use the C function fread(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. If you wish to handle reading data in another
-way, you need not call the png_init_io() function, but you must then
-implement the libpng I/O methods discussed in the Customizing Libpng
-section below.
-
- png_init_io(png_ptr, fp);
-
-If you had previously opened the file and read any of the signature from
-the beginning in order to see if this was a PNG file, you need to let
-libpng know that there are some bytes missing from the start of the file.
-
- png_set_sig_bytes(png_ptr, number);
-
-You can change the zlib compression buffer size to be used while
-reading compressed data with
-
- png_set_compression_buffer_size(png_ptr, buffer_size);
-
-where the default size is 8192 bytes. Note that the buffer size
-is changed immediately and the buffer is reallocated immediately,
-instead of setting a flag to be acted upon later.
-
-Setting up callback code
-
-You can set up a callback function to handle any unknown chunks in the
-input stream. You must supply the function
-
- read_chunk_callback(png_ptr ptr,
- png_unknown_chunkp chunk);
- {
- /* The unknown chunk structure contains your
- chunk data, along with similar data for any other
- unknown chunks: */
-
- png_byte name[5];
- png_byte *data;
- png_size_t size;
-
- /* Note that libpng has already taken care of
- the CRC handling */
-
- /* put your code here. Search for your chunk in the
- unknown chunk structure, process it, and return one
- of the following: */
-
- return (-n); /* chunk had an error */
- return (0); /* did not recognize */
- return (n); /* success */
- }
-
-(You can give your function another name that you like instead of
-"read_chunk_callback")
-
-To inform libpng about your function, use
-
- png_set_read_user_chunk_fn(png_ptr, user_chunk_ptr,
- read_chunk_callback);
-
-This names not only the callback function, but also a user pointer that
-you can retrieve with
-
- png_get_user_chunk_ptr(png_ptr);
-
-If you call the png_set_read_user_chunk_fn() function, then all unknown
-chunks will be saved when read, in case your callback function will need
-one or more of them. This behavior can be changed with the
-png_set_keep_unknown_chunks() function, described below.
-
-At this point, you can set up a callback function that will be
-called after each row has been read, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void read_row_callback(png_ptr ptr, png_uint_32 row,
- int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "read_row_callback")
-
-To inform libpng about your function, use
-

-Unknown-chunk handling
-
-Now you get to set the way the library processes unknown chunks in the
-input PNG stream. Both known and unknown chunks will be read. Normal
-behavior is that known chunks will be parsed into information in
-various info_ptr members while unknown chunks will be discarded. This
-behavior can be wasteful if your application will never use some known
-chunk types. To change this, you can call:
-
- png_set_keep_unknown_chunks(png_ptr, keep,
- chunk_list, num_chunks);
- keep - 0: default unknown chunk handling
- 1: ignore; do not keep
- 2: keep only if safe-to-copy
- 3: keep even if unsafe-to-copy
- You can use these definitions:
- PNG_HANDLE_CHUNK_AS_DEFAULT 0
- PNG_HANDLE_CHUNK_NEVER 1
- PNG_HANDLE_CHUNK_IF_SAFE 2
- PNG_HANDLE_CHUNK_ALWAYS 3
- chunk_list - list of chunks affected (a byte string,
- five bytes per chunk, NULL or '\0' if
- num_chunks is 0)
- num_chunks - number of chunks affected; if 0, all
- unknown chunks are affected. If nonzero,
- only the chunks in the list are affected
-
-Unknown chunks declared in this way will be saved as raw data onto a
-list of png_unknown_chunk structures. If a chunk that is normally
-known to libpng is named in the list, it will be handled as unknown,
-according to the "keep" directive. If a chunk is named in successive
-instances of png_set_keep_unknown_chunks(), the final instance will
-take precedence. The IHDR and IEND chunks should not be named in
-chunk_list; if they are, libpng will process them normally anyway.
-
-Here is an example of the usage of png_set_keep_unknown_chunks(),
-where the private "vpAg" chunk will later be processed by a user chunk
-callback function:
-
- png_byte vpAg[5]={118, 112, 65, 103, (png_byte) '\0'};
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- png_byte unused_chunks[]=
- {
- 104, 73, 83, 84, (png_byte) '\0', /* hIST */
- 105, 84, 88, 116, (png_byte) '\0', /* iTXt */
- 112, 67, 65, 76, (png_byte) '\0', /* pCAL */
- 115, 67, 65, 76, (png_byte) '\0', /* sCAL */
- 115, 80, 76, 84, (png_byte) '\0', /* sPLT */
- 116, 73, 77, 69, (png_byte) '\0', /* tIME */
- };
- #endif
-
- ...
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- /* ignore all unknown chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, NULL, 0);
- /* except for vpAg: */
- png_set_keep_unknown_chunks(read_ptr, 2, vpAg, 1);
- /* also ignore unused known chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, unused_chunks,
- (int)sizeof(unused_chunks)/5);
- #endif
-
-User limits
-
-The PNG specification allows the width and height of an image to be as
-large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
-Since very few applications really need to process such large images,
-we have imposed an arbitrary 1-million limit on rows and columns.
-Larger images will be rejected immediately with a png_error() call. If
-you wish to override this limit, you can use
-
- png_set_user_limits(png_ptr, width_max, height_max);
-
-to set your own limits, or use width_max = height_max = 0x7fffffffL
-to allow all valid dimensions (libpng may reject some very large images
-anyway because of potential buffer overflow conditions).
-
-You should put this statement after you create the PNG structure and
-before calling png_read_info(), png_read_png(), or png_process_data().
-If you need to retrieve the limits that are being applied, use
-
- width_max = png_get_user_width_max(png_ptr);
- height_max = png_get_user_height_max(png_ptr);
-
-The PNG specification sets no limit on the number of ancillary chunks
-allowed in a PNG datastream. You can impose a limit on the total number
-of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
-
- png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
-
-where 0x7fffffffL means unlimited. You can retrieve this limit with
-
- chunk_cache_max = png_get_chunk_cache_max(png_ptr);
-
-This limit also applies to the number of buffers that can be allocated
-by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.
-
-You can also set a limit on the amount of memory that a compressed chunk
-other than IDAT can occupy, with
-
- png_set_chunk_malloc_max(png_ptr, user_chunk_malloc_max);
-
-and you can retrieve the limit with
-
- chunk_malloc_max = png_get_chunk_malloc_max(png_ptr);
-
-Any chunks that would cause either of these limits to be exceeded will
-be ignored.
-
-The high-level read interface
-
-At this point there are two ways to proceed; through the high-level
-read interface, or through a sequence of low-level read operations.
-You can use the high-level interface if (a) you are willing to read
-the entire image into memory, and (b) the input transformations
-you want to do are limited to the following set:
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_STRIP_16 Strip 16-bit samples to
- 8 bits
- PNG_TRANSFORM_STRIP_ALPHA Discard the alpha channel
- PNG_TRANSFORM_PACKING Expand 1, 2 and 4-bit
- samples to bytes
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_EXPAND Perform set_expand()
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_GRAY_TO_RGB Expand grayscale samples
- to RGB (or GA to RGBA)
-
-(This excludes setting a background color, doing gamma transformation,
-quantizing, and setting filler.) If this is the case, simply do this:
-
- png_read_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some
-set of transformation flags. This call is equivalent to png_read_info(),
-followed the set of transformations indicated by the transform mask,
-then png_read_image(), and finally png_read_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future input transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_read_png().
-
-After you have called png_read_png(), you can retrieve the image data
-with
-
- row_pointers = png_get_rows(png_ptr, info_ptr);
-
-where row_pointers is an array of pointers to the pixel data for each row:
-
- png_bytep row_pointers[height];
-
-If you know your image size and pixel size ahead of time, you can allocate
-row_pointers prior to calling png_read_png() with
-
- if (height > PNG_UINT_32_MAX/png_sizeof(png_byte))
- png_error (png_ptr,
- "Image is too tall to process in memory");
- if (width > PNG_UINT_32_MAX/pixel_size)
- png_error (png_ptr,
- "Image is too wide to process in memory");
- row_pointers = png_malloc(png_ptr,
- height*png_sizeof(png_bytep));
- for (int i=0; i<height, i++)
- row_pointers[i]=NULL; /* security precaution */
- for (int i=0; i<height, i++)
- row_pointers[i]=png_malloc(png_ptr,
- width*pixel_size);
- png_set_rows(png_ptr, info_ptr, &row_pointers);
-
-Alternatively you could allocate your image in one big block and define
-row_pointers[i] to point into the proper places in your block.
-
-If you use png_set_rows(), the application is responsible for freeing
-row_pointers (and row_pointers[i], if they were separately allocated).
-
-If you don't allocate row_pointers ahead of time, png_read_png() will
-do it, and it'll be free'ed when you call png_destroy_*().
-
-The low-level read interface
-
-If you are going the low-level route, you are now ready to read all
-the file information up to the actual image data. You do this with a
-call to png_read_info().
-
- png_read_info(png_ptr, info_ptr);
-
-This will process all chunks up to but not including the image data.
-
-Querying the info structure
-
-Functions are used to get the information from the info_ptr once it
-has been read. Note that these fields may not be completely filled
-in until png_read_end() has read the chunk data following the image.
-
- png_get_IHDR(png_ptr, info_ptr, &width, &height,
- &bit_depth, &color_type, &interlace_type,
- &compression_type, &filter_method);
-
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels. (valid values are
- 1, 2, 4, 8, 16 and depend also on
- the color_type. See also
- significant bits (sBIT) below).
- color_type - describes which color/alpha channels
- are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)
- PNG_COLOR_TYPE_GRAY_ALPHA
- (bit depths 8, 16)
- PNG_COLOR_TYPE_PALETTE
- (bit depths 1, 2, 4, 8)
- PNG_COLOR_TYPE_RGB
- (bit_depths 8, 16)
- PNG_COLOR_TYPE_RGB_ALPHA
- (bit_depths 8, 16)
-
- PNG_COLOR_MASK_PALETTE
- PNG_COLOR_MASK_COLOR
- PNG_COLOR_MASK_ALPHA
-
- filter_method - (must be PNG_FILTER_TYPE_BASE
- for PNG 1.0, and can also be
- PNG_INTRAPIXEL_DIFFERENCING if
- the PNG datastream is embedded in
- a MNG-1.0 datastream)
- compression_type - (must be PNG_COMPRESSION_TYPE_BASE
- for PNG 1.0)
- interlace_type - (PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7)
-
- Any or all of interlace_type, compression_type, or
- filter_method can be NULL if you are
- not interested in their values.
-
- Note that png_get_IHDR() returns 32-bit data into
- the application's width and height variables.
- This is an unsafe situation if these are 16-bit
- variables. In such situations, the
- png_get_image_width() and png_get_image_height()
- functions described below are safer.
-
- width = png_get_image_width(png_ptr,
- info_ptr);
- height = png_get_image_height(png_ptr,
- info_ptr);
- bit_depth = png_get_bit_depth(png_ptr,
- info_ptr);
- color_type = png_get_color_type(png_ptr,
- info_ptr);
- filter_method = png_get_filter_type(png_ptr,
- info_ptr);
- compression_type = png_get_compression_type(png_ptr,
- info_ptr);
- interlace_type = png_get_interlace_type(png_ptr,
- info_ptr);
-
- channels = png_get_channels(png_ptr, info_ptr);
- channels - number of channels of info for the
- color type (valid values are 1 (GRAY,
- PALETTE), 2 (GRAY_ALPHA), 3 (RGB),
- 4 (RGB_ALPHA or RGB + filler byte))
- rowbytes = png_get_rowbytes(png_ptr, info_ptr);
- rowbytes - number of bytes needed to hold a row
-
- signature = png_get_signature(png_ptr, info_ptr);
- signature - holds the signature read from the
- file (if any). The data is kept in
- the same offset it would be if the
- whole signature were read (i.e. if an
- application had already read in 4
- bytes of signature before starting
- libpng, the remaining 4 bytes would
- be in signature[4] through signature[7]
- (see png_set_sig_bytes())).
-
-These are also important, but their validity depends on whether the chunk
-has been read. The png_get_valid(png_ptr, info_ptr, PNG_INFO_<chunk>) and
-png_get_<chunk>(png_ptr, info_ptr, ...) functions return non-zero if the
-data has been read, or zero if it is missing. The parameters to the
-png_get_<chunk> are set directly if they are simple data types, or a
-pointer into the info_ptr is returned for any complex types.
-
- png_get_PLTE(png_ptr, info_ptr, &palette,
- &num_palette);
- palette - the palette for the file
- (array of png_color)
- num_palette - number of entries in the palette
-
- png_get_gAMA(png_ptr, info_ptr, &gamma);
- gamma - the gamma the file is written
- at (PNG_INFO_gAMA)
-
- png_get_sRGB(png_ptr, info_ptr, &srgb_intent);
- srgb_intent - the rendering intent (PNG_INFO_sRGB)
- The presence of the sRGB chunk
- means that the pixel data is in the
- sRGB color space. This chunk also
- implies specific values of gAMA and
- cHRM.
-
- png_get_iCCP(png_ptr, info_ptr, &name,
- &compression_type, &profile, &proflen);
- name - The profile name.
- compression - The compression type; always
- PNG_COMPRESSION_TYPE_BASE for PNG 1.0.
- You may give NULL to this argument to
- ignore it.
- profile - International Color Consortium color
- profile data. May contain NULs.
- proflen - length of profile data in bytes.
-
- png_get_sBIT(png_ptr, info_ptr, &sig_bit);
- sig_bit - the number of significant bits for
- (PNG_INFO_sBIT) each of the gray,
- red, green, and blue channels,
- whichever are appropriate for the
- given color type (png_color_16)
-
- png_get_tRNS(png_ptr, info_ptr, &trans_alpha,
- &num_trans, &trans_color);
- trans_alpha - array of alpha (transparency)
- entries for palette (PNG_INFO_tRNS)
- trans_color - graylevel or color sample values of
- the single transparent color for
- non-paletted images (PNG_INFO_tRNS)

- valid 16-bit red, green and blue
- values, regardless of color_type
-
- num_comments = png_get_text(png_ptr, info_ptr,
- &text_ptr, &num_text);
- num_comments - number of comments
- text_ptr - array of png_text holding image
- comments
- text_ptr[i].compression - type of compression used
- on "text" PNG_TEXT_COMPRESSION_NONE
- PNG_TEXT_COMPRESSION_zTXt
- PNG_ITXT_COMPRESSION_NONE
- PNG_ITXT_COMPRESSION_zTXt
- text_ptr[i].key - keyword for comment. Must contain
- 1-79 characters.
- text_ptr[i].text - text comments for current
- keyword. Can be empty.
- text_ptr[i].text_length - length of text string,
- after decompression, 0 for iTXt
- text_ptr[i].itxt_length - length of itxt string,

- text_ptr[i].lang - language of comment (empty
- string for unknown).
- text_ptr[i].lang_key - keyword in UTF-8
- (empty string for unknown).
- Note that the itxt_length, lang, and lang_key
- members of the text_ptr structure only exist
- when the library is built with iTXt chunk support.
-
- num_text - number of comments (same as
- num_comments; you can put NULL here
- to avoid the duplication)
- Note while png_set_text() will accept text, language,
- and translated keywords that can be NULL pointers, the
- structure returned by png_get_text will always contain
- regular zero-terminated C strings. They might be
- empty strings but they will never be NULL pointers.
-
- num_spalettes = png_get_sPLT(png_ptr, info_ptr,
- &palette_ptr);
- palette_ptr - array of palette structures holding
- contents of one or more sPLT chunks
- read.

-
- png_get_oFFs(png_ptr, info_ptr, &offset_x, &offset_y,
- &unit_type);
- offset_x - positive offset from the left edge
- of the screen
- offset_y - positive offset from the top edge
- of the screen
- unit_type - PNG_OFFSET_PIXEL, PNG_OFFSET_MICROMETER
-
- png_get_pHYs(png_ptr, info_ptr, &res_x, &res_y,
- &unit_type);
- res_x - pixels/unit physical resolution in
- x direction
- res_y - pixels/unit physical resolution in
- x direction
- unit_type - PNG_RESOLUTION_UNKNOWN,
- PNG_RESOLUTION_METER
-
- png_get_sCAL(png_ptr, info_ptr, &unit, &width,

- (width and height are strings like "2.54")
-
- num_unknown_chunks = png_get_unknown_chunks(png_ptr,
- info_ptr, &unknowns)
- unknowns - array of png_unknown_chunk
- structures holding unknown chunks
- unknowns[i].name - name of unknown chunk
- unknowns[i].data - data of unknown chunk
- unknowns[i].size - size of unknown chunk's data
- unknowns[i].location - position of chunk in file
-
- The value of "i" corresponds to the order in which the
- chunks were read from the PNG file or inserted with the
- png_set_unknown_chunks() function.
-
-The data from the pHYs chunk can be retrieved in several convenient
-forms:
-
- res_x = png_get_x_pixels_per_meter(png_ptr,
- info_ptr)
- res_y = png_get_y_pixels_per_meter(png_ptr,
- info_ptr)
- res_x_and_y = png_get_pixels_per_meter(png_ptr,
- info_ptr)
- res_x = png_get_x_pixels_per_inch(png_ptr,
- info_ptr)
- res_y = png_get_y_pixels_per_inch(png_ptr,
- info_ptr)
- res_x_and_y = png_get_pixels_per_inch(png_ptr,
- info_ptr)
- aspect_ratio = png_get_pixel_aspect_ratio(png_ptr,
- info_ptr)
-
- (Each of these returns 0 [signifying "unknown"] if
- the data is not present or if res_x is 0;
- res_x_and_y is 0 if res_x != res_y)
-
-The data from the oFFs chunk can be retrieved in several convenient
-forms:
-
- x_offset = png_get_x_offset_microns(png_ptr, info_ptr);
- y_offset = png_get_y_offset_microns(png_ptr, info_ptr);
- x_offset = png_get_x_offset_inches(png_ptr, info_ptr);
- y_offset = png_get_y_offset_inches(png_ptr, info_ptr);
-
- (Each of these returns 0 [signifying "unknown" if both
- x and y are 0] if the data is not present or if the
- chunk is present but the unit is the pixel)
-
-For more information, see the png_info definition in png.h and the
-PNG specification for chunk contents. Be careful with trusting
-rowbytes, as some of the transformations could increase the space
-needed to hold a row (expand, filler, gray_to_rgb, etc.).
-See png_read_update_info(), below.
-
-A quick word about text_ptr and num_text. PNG stores comments in
-keyword/text pairs, one pair per chunk, with no limit on the number
-of text chunks, and a 2^31 byte limit on their size. While there are
-suggested keywords, there is no requirement to restrict the use to these
-strings. It is strongly suggested that keywords and text be sensible
-to humans (that's the point), so don't use abbreviations. Non-printing
-symbols are not allowed. See the PNG specification for more details.
-There is also no requirement to have text after the keyword.
-
-Keywords should be limited to 79 Latin-1 characters without leading or
-trailing spaces, but non-consecutive spaces are allowed within the
-keyword. It is possible to have the same keyword any number of times.
-The text_ptr is an array of png_text structures, each holding a
-pointer to a language string, a pointer to a keyword and a pointer to
-a text string. The text string, language code, and translated
-keyword may be empty or NULL pointers. The keyword/text
-pairs are put into the array in the order that they are received.
-However, some or all of the text chunks may be after the image, so, to
-make sure you have read all the text chunks, don't mess with these
-until after you read the stuff after the image. This will be
-mentioned again below in the discussion that goes with png_read_end().
-
-Input transformations
-
-After you've read the header information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-The colors used for the background and transparency values should be
-supplied in the same format/depth as the current image data. They
-are stored in the same format/depth as the image data in a bKGD or tRNS
-chunk, so this is what libpng expects for this data. The colors are
-transformed to keep in sync with the image data when an application
-calls the png_read_update_info() routine (see below).
-
-Data will be decoded into the supplied row buffers packed into bytes
-unless the library has been told to transform it into another format.
-For example, 4 bit/pixel paletted or grayscale data will be returned
-2 pixels/byte with the leftmost pixel in the high-order bits of the
-byte, unless png_set_packing() is called. 8-bit RGB data will be stored
-in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha()
-is called to insert filler bytes, either before or after each RGB triplet.
-16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant
-byte of the color value first, unless png_set_strip_16() is called to
-transform it to regular RGB RGB triplets, or png_set_filler() or
-png_set_add alpha() is called to insert filler bytes, either before or
-after each RRGGBB triplet. Similarly, 8-bit or 16-bit grayscale data can
-be modified with
-png_set_filler(), png_set_add_alpha(), or png_set_strip_16().
-
-The following code transforms grayscale images of less than 8 to 8 bits,
-changes paletted images to RGB, and adds a full alpha channel if there is
-transparency information in a tRNS chunk. This is most useful on
-grayscale images with bit depths of 2 or 4 or if there is a multiple-image
-viewing application that wishes to treat all images in the same way.
-
- if (color_type == PNG_COLOR_TYPE_PALETTE)
- png_set_palette_to_rgb(png_ptr);
-
- if (color_type == PNG_COLOR_TYPE_GRAY &&
- bit_depth < 8) png_set_expand_gray_1_2_4_to_8(png_ptr);
-
- if (png_get_valid(png_ptr, info_ptr,
- PNG_INFO_tRNS)) png_set_tRNS_to_alpha(png_ptr);
-
-These three functions are actually aliases for png_set_expand(), added
-in libpng version 1.0.4, with the function names expanded to improve code
-readability. In some future version they may actually do different
-things.
-
-As of libpng version 1.2.9, png_set_expand_gray_1_2_4_to_8() was
-added. It expands the sample depth without changing tRNS to alpha.
-
-As of libpng version 1.4.4, not all possible expansions are supported.
-
-In the following table, the 01 means grayscale with depth<8, 31 means
-indexed with depth<8, other numerals represent the color type, "T" means
-the tRNS chunk is present, A means an alpha channel is present, and O
-means tRNS or alpha is present but all pixels in the image are opaque.

- if (color_type & PNG_COLOR_MASK_ALPHA)
- png_set_strip_alpha(png_ptr);
-
-In PNG files, the alpha channel in an image
-is the level of opacity. If you need the alpha channel in an image to
-be the level of transparency instead of opacity, you can invert the
-alpha channel (or the tRNS chunk data) after it's read, so that 0 is
-fully opaque and 255 (in 8-bit or paletted images) or 65535 (in 16-bit
-images) is fully transparent, with
-
- png_set_invert_alpha(png_ptr);
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit
-files. This code expands to 1 pixel per byte without changing the
-values of the pixels:
-
- if (bit_depth < 8)
- png_set_packing(png_ptr);
-
-PNG files have possible bit depths of 1, 2, 4, 8, and 16. All pixels
-stored in a PNG image have been "scaled" or "shifted" up to the next
-higher possible bit depth (e.g. from 5 bits/sample in the range [0,31]
-to 8 bits/sample in the range [0, 255]). However, it is also possible
-to convert the PNG pixel data back to the original bit depth of the
-image. This call reduces the pixels back down to the original bit depth:
-
- png_color_8p sig_bit;
-
- if (png_get_sBIT(png_ptr, info_ptr, &sig_bit))
- png_set_shift(png_ptr, sig_bit);
-
-PNG files store 3-color pixels in red, green, blue order. This code
-changes the storage of the pixels to blue, green, red:
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_bgr(png_ptr);
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code expands them
-into 4 or 8 bytes for windowing systems that need them in this format:
-
- if (color_type == PNG_COLOR_TYPE_RGB)
- png_set_filler(png_ptr, filler, PNG_FILLER_BEFORE);
-
-where "filler" is the 8 or 16-bit number to fill with, and the location is
-either PNG_FILLER_BEFORE or PNG_FILLER_AFTER, depending upon whether
-you want the filler before the RGB or after. This transformation
-does not affect images that already have full alpha channels. To add an
-opaque alpha channel, use filler=0xff or 0xffff and PNG_FILLER_AFTER which
-will generate RGBA pixels.
-
-Note that png_set_filler() does not change the color type. If you want
-to do that, you can add a true alpha channel with
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_GRAY)
- png_set_add_alpha(png_ptr, filler, PNG_FILLER_AFTER);
-
-where "filler" contains the alpha value to assign to each pixel.
-This function was added in libpng-1.2.7.
-
-If you are reading an image with an alpha channel, and you need the
-data as ARGB instead of the normal PNG format RGBA:
-
- if (color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_swap_alpha(png_ptr);
-
-For some uses, you may want a grayscale image to be represented as
-RGB. This code will do that conversion:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_gray_to_rgb(png_ptr);
-
-Conversely, you can convert an RGB or RGBA image to grayscale or grayscale
-with alpha.
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_rgb_to_gray_fixed(png_ptr, error_action,
- int red_weight, int green_weight);
-
- error_action = 1: silently do the conversion
- error_action = 2: issue a warning if the original
- image has any pixel where
- red != green or red != blue
- error_action = 3: issue an error and abort the
- conversion if the original
- image has any pixel where
- red != green or red != blue
-
- red_weight: weight of red component times 100000
- green_weight: weight of green component times 100000
- If either weight is negative, default
- weights (21268, 71514) are used.
-
-If you have set error_action = 1 or 2, you can
-later check whether the image really was gray, after processing
-the image rows, with the png_get_rgb_to_gray_status(png_ptr) function.
-It will return a png_byte that is zero if the image was gray or
-1 if there were any non-gray pixels. bKGD and sBIT data
-will be silently converted to grayscale, using the green channel
-data, regardless of the error_action setting.
-
-With red_weight+green_weight<=100000,
-the normalized graylevel is computed:
-
- int rw = red_weight * 65536;
- int gw = green_weight * 65536;
- int bw = 65536 - (rw + gw);
- gray = (rw*red + gw*green + bw*blue)/65536;
-

-
- Y = 0.212671 * R + 0.715160 * G + 0.072169 * B
-
-Libpng approximates this with
-
- Y = 0.21268 * R + 0.7151 * G + 0.07217 * B
-
-which can be expressed with integers as
-
- Y = (6969 * R + 23434 * G + 2365 * B)/32768
-
-The calculation is done in a linear colorspace, if the image gamma
-is known.
-
-If you have a grayscale and you are using png_set_expand_depth(),
-png_set_expand(), or png_set_gray_to_rgb to change to truecolor or to
-a higher bit-depth, you must either supply the background color as a gray
-value at the original file bit-depth (need_expand = 1) or else supply the
-background color as an RGB triplet at the final, expanded bit depth
-(need_expand = 0). Similarly, if you are reading a paletted image, you
-must either supply the background color as a palette index (need_expand = 1)
-or as an RGB triplet that may or may not be in the palette (need_expand = 0).
-
- png_color_16 my_background;

-
- if (png_get_bKGD(png_ptr, info_ptr, &image_background))

- PNG_BACKGROUND_GAMMA_FILE, 1, 1.0);
- else
- png_set_background(png_ptr, &my_background,
- PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
-
-The png_set_background() function tells libpng to composite images
-with alpha or simple transparency against the supplied background
-color. If the PNG file contains a bKGD chunk (PNG_INFO_bKGD valid),
-you may use this color, or supply another color more suitable for
-the current display (e.g., the background color from a web page). You
-need to tell libpng whether the color is in the gamma space of the
-display (PNG_BACKGROUND_GAMMA_SCREEN for colors you supply), the file
-(PNG_BACKGROUND_GAMMA_FILE for colors from the bKGD chunk), or one
-that is neither of these gammas (PNG_BACKGROUND_GAMMA_UNIQUE - I don't
-know why anyone would use this, but it's here).
-
-To properly display PNG images on any kind of system, the application needs
-to know what the display gamma is. Ideally, the user will know this, and
-the application will allow them to set it. One method of allowing the user
-to set the display gamma separately for each system is to check for a
-SCREEN_GAMMA or DISPLAY_GAMMA environment variable, which will hopefully be
-correctly set.
-
-Note that display_gamma is the overall gamma correction required to produce
-pleasing results, which depends on the lighting conditions in the surrounding
-environment. In a dim or brightly lit room, no compensation other than
-the physical gamma exponent of the monitor is needed, while in a dark room
-a slightly smaller exponent is better.
-
- double gamma, screen_gamma;
-
- if (/* We have a user-defined screen
- gamma value */)
- {
- screen_gamma = user_defined_screen_gamma;
- }
- /* One way that applications can share the same
- screen gamma value */
- else if ((gamma_str = getenv("SCREEN_GAMMA"))
- != NULL)
- {
- screen_gamma = (double)atof(gamma_str);
- }
- /* If we don't have another value */
- else
- {
- screen_gamma = 2.2; /* A good guess for a
- PC monitor in a bright office or a dim room */
- screen_gamma = 2.0; /* A good guess for a
- PC monitor in a dark room */
- screen_gamma = 1.7 or 1.0; /* A good
- guess for Mac systems */
- }
-
-The png_set_gamma() function handles gamma transformations of the data.
-Pass both the file gamma and the current screen_gamma. If the file does
-not have a gamma value, you can pass one anyway if you have an idea what
-it is (usually 0.45455 is a good guess for GIF images on PCs). Note
-that file gammas are inverted from screen gammas. See the discussions
-on gamma in the PNG specification for an excellent description of what
-gamma is, and why all applications should support it. It is strongly
-recommended that PNG viewers support gamma correction.
-
- if (png_get_gAMA(png_ptr, info_ptr, &gamma))
- png_set_gamma(png_ptr, screen_gamma, gamma);
- else
- png_set_gamma(png_ptr, screen_gamma, 0.45455);
-
-If you need to reduce an RGB file to a paletted file, or if a paletted
-file has more entries then will fit on your screen, png_set_quantize()
-will do that. Note that this is a simple match dither that merely
-finds the closest color available. This should work fairly well with
-optimized palettes, and fairly badly with linear color cubes. If you
-pass a palette that is larger then maximum_colors, the file will
-reduce the number of colors in the palette so it will fit into
-maximum_colors. If there is a histogram, it will use it to make
-more intelligent choices when reducing the palette. If there is no
-histogram, it may not do as good a job.
-
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- if (png_get_valid(png_ptr, info_ptr,
- PNG_INFO_PLTE))
- {
- png_uint_16p histogram = NULL;
-
- png_get_hIST(png_ptr, info_ptr,

-
- png_set_quantize(png_ptr, std_color_cube,

- NULL,0);
- }
- }
-
-PNG files describe monochrome as black being zero and white being one.
-The following code will reverse this (make black be one and white be
-zero):
-
- if (bit_depth == 1 && color_type == PNG_COLOR_TYPE_GRAY)
- png_set_invert_mono(png_ptr);
-
-This function can also be used to invert grayscale and gray-alpha images:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_invert_mono(png_ptr);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code changes the storage to the
-other way (little-endian, i.e. least significant bits first, the
-way PCs store them):
-
- if (bit_depth == 16)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_read_user_transform_fn(png_ptr,
- read_transform_fn);
-
-You must supply the function
-
- void read_transform_fn(png_ptr ptr, row_info_ptr
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-after all of the other transformations have been processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function, and you can inform libpng that your transform
-function will change the number of channels or bit depth with the
-function
-
- png_set_user_transform_info(png_ptr, user_ptr,
- user_depth, user_channels);
-
-The user's application, not libpng, is responsible for allocating and
-freeing any memory required for the user structure.
-
-You can retrieve the pointer via the function
-png_get_user_transform_ptr(). For example:
-
- voidp read_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-The last thing to handle is interlacing; this is covered in detail below,
-but you must call the function here if you want libpng to handle expansion
-of the interlaced image.
-
- number_of_passes = png_set_interlace_handling(png_ptr);
-
-After setting the transformations, libpng can update your png_info
-structure to reflect any transformations you've requested with this
-call. This is most useful to update the info structure's rowbytes
-field so you can use it to allocate your image memory. This function
-will also update your palette with the correct screen_gamma and
-background if these have been given with the calls above.
-
- png_read_update_info(png_ptr, info_ptr);
-
-After you call png_read_update_info(), you can allocate any
-memory you need to hold the image. The row data is simply
-raw byte data for all forms of images. As the actual allocation
-varies among applications, no example will be given. If you
-are allocating one large chunk, you will need to build an
-array of pointers to each row, as it will be needed for some
-of the functions below.
-
-Reading image data
-
-After you've allocated memory, you can read the image data.
-The simplest way to do this is in one function call. If you are
-allocating enough memory to hold the whole image, you can just
-call png_read_image() and libpng will read in all the image data
-and put it in the memory area supplied. You will need to pass in
-an array of pointers to each row.
-
-This function automatically handles interlacing, so you don't need
-to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_read_rows().
-
- png_read_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_bytep row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to read in the whole image at once, you can
-use png_read_rows() instead. If there is no interlacing (check
-interlace_type == PNG_INTERLACE_NONE), this is simple:
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-where row_pointers is the same as in the png_read_image() call.
-
-If you are doing this just one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
- png_read_row(png_ptr, row_pointer, NULL);
-
-If the file is interlaced (interlace_type != 0 in the IHDR chunk), things
-get somewhat harder. The only current (PNG Specification version 1.2)
-interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7)
-is a somewhat complicated 2D interlace scheme, known as Adam7, that
-breaks down an image into seven smaller images of varying size, based
-on an 8x8 grid.
-
-libpng can fill out those images or it can give them to you "as is".
-If you want them filled out, there are two ways to do that. The one
-mentioned in the PNG specification is to expand each pixel to cover
-those pixels that have not been read yet (the "rectangle" method).
-This results in a blocky image for the first pass, which gradually
-smooths out as more pixels are read. The other method is the "sparkle"
-method, where pixels are drawn only in their final locations, with the
-rest of the image remaining whatever colors they were initialized to
-before the start of the read. The first method usually looks better,
-but tends to be slower, as there are more pixels to put in the rows.
-
-If you don't want libpng to handle the interlacing details, just call
-png_read_rows() seven times to read in all seven images. Each of the
-images is a valid image by itself, or they can all be combined on an
-8x8 grid to form a single image (although if you intend to combine them
-you would be far better off using the libpng interlace handling).
-
-The first pass will return an image 1/8 as wide as the entire image
-(every 8th column starting in column 0) and 1/8 as high as the original
-(every 8th row starting in row 0), the second will be 1/8 as wide
-(starting in column 4) and 1/8 as high (also starting in row 0). The
-third pass will be 1/4 as wide (every 4th pixel starting in column 0) and
-1/8 as high (every 8th row starting in row 4), and the fourth pass will
-be 1/4 as wide and 1/4 as high (every 4th column starting in column 2,
-and every 4th row starting in row 0). The fifth pass will return an
-image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2),
-while the sixth pass will be 1/2 as wide and 1/2 as high as the original
-(starting in column 1 and row 0). The seventh and final pass will be as
-wide as the original, and 1/2 as high, containing all of the odd
-numbered scanlines. Phew!
-
-If you want libpng to expand the images, call this before calling
-png_start_read_image() or png_read_update_info():
-
- if (interlace_type == PNG_INTERLACE_ADAM7)
- number_of_passes
- = png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this
-is seven, but may change if another interlace type is added.
-This function can be called even if the file is not interlaced,
-where it will return one pass.
-
-If you are not going to display the image after each pass, but are
-going to wait until the entire image is read in, use the sparkle
-effect. This effect is faster and the end result of either method
-is exactly the same. If you are planning on displaying the image
-after each pass, the "rectangle" effect is generally considered the
-better looking one.
-
-If you only want the "sparkle" effect, just call png_read_rows() as
-normal, with the third parameter NULL. Make sure you make pass over
-the image number_of_passes times, and you don't change the data in the
-rows between calls. You can change the locations of the data, just
-not the data. Each pass only writes the pixels appropriate for that
-pass, and assumes the data from previous passes is still valid.
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-If you only want the first effect (the rectangles), do the same as
-before except pass the row buffer in the third parameter, and leave
-the second parameter NULL.
-
- png_read_rows(png_ptr, NULL, row_pointers,
- number_of_rows);
-
-Finishing a sequential read
-
-After you are finished reading the image through the
-low-level interface, you can finish reading the file. If you are
-interested in comments or time, which may be stored either before or
-after the image data, you should pass the separate png_info struct if
-you want to keep the comments from before and after the image
-separate. If you are not interested, you can pass NULL.
-
- png_read_end(png_ptr, end_info);
-
-When you are done, you can free all memory allocated by libpng like this:
-
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-This function only affects data that has already been allocated.
-You can call this function after reading the PNG data but before calling
-any png_set_*() functions, to control whether the user or the png_set_*()
-function is responsible for freeing any existing data that might be present,
-and again after the png_set_*() functions to control whether the user
-or png_destroy_*() is supposed to free the data. When the user assumes
-responsibility for libpng-allocated data, the application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated your row_pointers in a single block, as suggested above in
-the description of the high level read interface, you must not transfer
-responsibility for freeing it to the png_set_rows or png_read_destroy function,
-because they would also try to free the individual row_pointers[i].
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-
-The png_free_data() function will turn off the "valid" flag for anything
-it frees. If you need to turn the flag off for a chunk that was freed by
-your application instead of by libpng, you can use
-
- png_set_invalid(png_ptr, info_ptr, mask);
- mask - identifies the chunks to be made invalid,
- containing the bitwise OR of one or
- more of
- PNG_INFO_gAMA, PNG_INFO_sBIT,
- PNG_INFO_cHRM, PNG_INFO_PLTE,
- PNG_INFO_tRNS, PNG_INFO_bKGD,
- PNG_INFO_hIST, PNG_INFO_pHYs,
- PNG_INFO_oFFs, PNG_INFO_tIME,
- PNG_INFO_pCAL, PNG_INFO_sRGB,
- PNG_INFO_iCCP, PNG_INFO_sPLT,
- PNG_INFO_sCAL, PNG_INFO_IDAT
-
-For a more compact example of reading a PNG image, see the file example.c.
-
-Reading PNG files progressively
-
-The progressive reader is slightly different then the non-progressive
-reader. Instead of calling png_read_info(), png_read_rows(), and
-png_read_end(), you make one call to png_process_data(), which calls
-callbacks when it has the info, a row, or the end of the image. You
-set up these callbacks with png_set_progressive_read_fn(). You don't
-have to worry about the input/output functions of libpng, as you are
-giving the library the data directly in png_process_data(). I will
-assume that you have read the section on reading PNG files above,
-so I will only highlight the differences (although I will show
-all of the code).

- want to display any rows that were generated

-
-
-IV. Writing
-
-Much of this is very similar to reading. However, everything of
-importance is repeated here, so you won't have to constantly look
-back up in the reading section to understand writing.
-
-Setup
-
-You will want to do the I/O initialization before you get into libpng,
-so if it doesn't work, you don't have anything to undo. If you are not
-using the standard I/O functions, you will need to replace them with
-custom writing functions. See the discussion under Customizing libpng.
-
- FILE *fp = fopen(file_name, "wb");
- if (!fp)
- {
- return (ERROR);
- }
-
-Next, png_struct and png_info need to be allocated and initialized.
-As these can be both relatively large, you may not want to store these
-on the stack, unless you have stack space to spare. Of course, you
-will want to check if they return NULL. If you are also reading,
-you won't want to name your read structure and your write structure
-both "png_ptr"; you can call them anything you like, such as
-"read_ptr" and "write_ptr". Look at pngtest.c, for example.
-
- png_structp png_ptr = png_create_write_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_write_struct(&png_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_write_struct_2() instead of png_create_write_struct():
-
- png_structp png_ptr = png_create_write_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-After you have these structures, you will need to set up the
-error handling. When libpng encounters an error, it expects to
-longjmp() back to your routine. Therefore, you will need to call
-setjmp() and pass the png_jmpbuf(png_ptr). If you
-write the file from different routines, you will need to update
-the png_jmpbuf(png_ptr) every time you enter a new routine that will
-call a png_*() function. See your documentation of setjmp/longjmp
-for your compiler for more information on setjmp/longjmp. See
-the discussion on libpng error handling in the Customizing Libpng
-section below for more information on the libpng error handling.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_write_struct(&png_ptr, &info_ptr);
- fclose(fp);
- return (ERROR);
- }
- ...
- return;
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the output code. The default for libpng is to
-use the C function fwrite(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. Again, if you wish to handle writing data in
-another way, see the discussion on libpng I/O handling in the Customizing
-Libpng section below.
-
- png_init_io(png_ptr, fp);
-
-If you are embedding your PNG into a datastream such as MNG, and don't
-want libpng to write the 8-byte signature, or if you have already
-written the signature in your application, use
-
- png_set_sig_bytes(png_ptr, 8);
-
-to inform libpng that it should not write a signature.
-
-Write callbacks
-
-At this point, you can set up a callback function that will be
-called after each row has been written, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void write_row_callback(png_ptr, png_uint_32 row,
- int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "write_row_callback")
-
-To inform libpng about your function, use
-
- png_set_write_status_fn(png_ptr, write_row_callback);
-
-You now have the option of modifying how the compression library will
-run. The following functions are mainly for testing, but may be useful
-in some cases, like if you need to write PNG files extremely fast and
-are willing to give up some compression, or if you want to get the
-maximum possible compression at the expense of slower writing. If you
-have no special needs in this area, let the library do what it wants by
-not calling this function at all, as it has been tuned to deliver a good
-speed/compression ratio. The second parameter to png_set_filter() is
-the filter method, for which the only valid values are 0 (as of the
-July 1999 PNG specification, version 1.2) or 64 (if you are writing
-a PNG datastream that is to be embedded in a MNG datastream). The third
-parameter is a flag that indicates which filter type(s) are to be tested
-for each scanline. See the PNG specification for details on the specific
-filter types.
-
-
- /* turn on or off filtering, and/or choose
- specific filters. You can use either a single
- PNG_FILTER_VALUE_NAME or the bitwise OR of one
- or more PNG_FILTER_NAME masks. */
- png_set_filter(png_ptr, 0,
- PNG_FILTER_NONE | PNG_FILTER_VALUE_NONE |
- PNG_FILTER_SUB | PNG_FILTER_VALUE_SUB |
- PNG_FILTER_UP | PNG_FILTER_VALUE_UP |
- PNG_FILTER_AVG | PNG_FILTER_VALUE_AVG |
- PNG_FILTER_PAETH | PNG_FILTER_VALUE_PAETH|
- PNG_ALL_FILTERS);
-
-If an application
-wants to start and stop using particular filters during compression,
-it should start out with all of the filters (to ensure that the previous
-row of pixels will be stored in case it's needed later), and then add
-and remove them after the start of compression.
-
-If you are writing a PNG datastream that is to be embedded in a MNG
-datastream, the second parameter can be either 0 or 64.
-
-The png_set_compression_*() functions interface to the zlib compression
-library, and should mostly be ignored unless you really know what you are
-doing. The only generally useful call is png_set_compression_level()
-which changes how much time zlib spends on trying to compress the image
-data. See the Compression Library (zlib.h and algorithm.txt, distributed
-with zlib) for details on the compression levels.
-
- /* set the zlib compression level */
- png_set_compression_level(png_ptr,
- Z_BEST_COMPRESSION);
-
- /* set other zlib parameters */
- png_set_compression_mem_level(png_ptr, 8);
- png_set_compression_strategy(png_ptr,
- Z_DEFAULT_STRATEGY);
- png_set_compression_window_bits(png_ptr, 15);
- png_set_compression_method(png_ptr, 8);
- png_set_compression_buffer_size(png_ptr, 8192)
-
-extern PNG_EXPORT(void,png_set_zbuf_size)
-
-Setting the contents of info for output
-
-You now need to fill in the png_info structure with all the data you
-wish to write before the actual image. Note that the only thing you
-are allowed to write after the image is the text chunks and the time
-chunk (as of PNG Specification 1.2, anyway). See png_write_end() and
-the latest PNG specification for more information on that. If you
-wish to write them before the image, fill them in now, and flag that
-data as being valid. If you want to wait until after the data, don't
-fill them until png_write_end(). For all the fields in png_info and
-their data types, see png.h. For explanations of what the fields
-contain, see the PNG specification.
-
-Some of the more important parts of the png_info are:
-
- png_set_IHDR(png_ptr, info_ptr, width, height,
- bit_depth, color_type, interlace_type,
- compression_type, filter_method)
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels.
- (valid values are 1, 2, 4, 8, 16
- and depend also on the
- color_type. See also significant
- bits (sBIT) below).
- color_type - describes which color/alpha
- channels are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)
- PNG_COLOR_TYPE_GRAY_ALPHA
- (bit depths 8, 16)
- PNG_COLOR_TYPE_PALETTE
- (bit depths 1, 2, 4, 8)
- PNG_COLOR_TYPE_RGB
- (bit_depths 8, 16)
- PNG_COLOR_TYPE_RGB_ALPHA
- (bit_depths 8, 16)
-
- PNG_COLOR_MASK_PALETTE
- PNG_COLOR_MASK_COLOR
- PNG_COLOR_MASK_ALPHA
-
- interlace_type - PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7
- compression_type - (must be
- PNG_COMPRESSION_TYPE_DEFAULT)
- filter_method - (must be PNG_FILTER_TYPE_DEFAULT
- or, if you are writing a PNG to
- be embedded in a MNG datastream,
- can also be
- PNG_INTRAPIXEL_DIFFERENCING)
-
-If you call png_set_IHDR(), the call must appear before any of the
-other png_set_*() functions, because they might require access to some of
-the IHDR settings. The remaining png_set_*() functions can be called
-in any order.
-
-If you wish, you can reset the compression_type, interlace_type, or
-filter_method later by calling png_set_IHDR() again; if you do this, the
-width, height, bit_depth, and color_type must be the same in each call.

-
-The "location" member is set automatically according to
-what part of the output file has already been written.
-You can change its value after calling png_set_unknown_chunks()
-as demonstrated in pngtest.c. Within each of the "locations",
-the chunks are sequenced according to their position in the
-structure (that is, the value of "i", which is the order in which
-the chunk was either read from the input file or defined with
-png_set_unknown_chunks).
-
-A quick word about text and num_text. text is an array of png_text
-structures. num_text is the number of valid structures in the array.
-Each png_text structure holds a language code, a keyword, a text value,
-and a compression type.
-
-The compression types have the same valid numbers as the compression
-types of the image data. Currently, the only valid number is zero.
-However, you can store text either compressed or uncompressed, unlike
-images, which always have to be compressed. So if you don't want the
-text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE.
-Because tEXt and zTXt chunks don't have a language field, if you
-specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt
-any language code or translated keyword will not be written out.
-
-Until text gets around 1000 bytes, it is not worth compressing it.
-After the text has been written out to the file, the compression type
-is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR,
-so that it isn't written out again at the end (in case you are calling
-png_write_end() with the same struct.
-
-The keywords that are given in the PNG Specification are:
-
- Title Short (one line) title or
- caption for image
- Author Name of image's creator
- Description Description of image (possibly long)
- Copyright Copyright notice
- Creation Time Time of original image creation
- (usually RFC 1123 format, see below)
- Software Software used to create the image
- Disclaimer Legal disclaimer
- Warning Warning of nature of content
- Source Device used to create the image
- Comment Miscellaneous comment; conversion
- from other image format
-
-The keyword-text pairs work like this. Keywords should be short
-simple descriptions of what the comment is about. Some typical
-keywords are found in the PNG specification, as is some recommendations
-on keywords. You can repeat keywords in a file. You can even write
-some text before the image and some after. For example, you may want
-to put a description of the image before the image, but leave the
-disclaimer until after, so viewers working over modem connections
-don't have to wait for the disclaimer to go over the modem before
-they start seeing the image. Finally, keywords should be full
-words, not abbreviations. Keywords and text are in the ISO 8859-1
-(Latin-1) character set (a superset of regular ASCII) and can not
-contain NUL characters, and should not contain control or other
-unprintable characters. To make the comments widely readable, stick
-with basic ASCII, and avoid machine specific character set extensions
-like the IBM-PC character set. The keyword must be present, but
-you can leave off the text string on non-compressed pairs.
-Compressed pairs must have a text string, as only the text string
-is compressed anyway, so the compression would be meaningless.
-
-PNG supports modification time via the png_time structure. Two
-conversion routines are provided, png_convert_from_time_t() for
-time_t and png_convert_from_struct_tm() for struct tm. The
-time_t routine uses gmtime(). You don't have to use either of
-these, but if you wish to fill in the png_time structure directly,
-you should provide the time in universal time (GMT) if possible
-instead of your local time. Note that the year number is the full
-year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and
-that months start with 1.
-
-If you want to store the time of the original image creation, you should
-use a plain tEXt chunk with the "Creation Time" keyword. This is
-necessary because the "creation time" of a PNG image is somewhat vague,
-depending on whether you mean the PNG file, the time the image was
-created in a non-PNG format, a still photo from which the image was
-scanned, or possibly the subject matter itself. In order to facilitate
-machine-readable dates, it is recommended that the "Creation Time"
-tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"),
-although this isn't a requirement. Unlike the tIME chunk, the
-"Creation Time" tEXt chunk is not expected to be automatically changed
-by the software. To facilitate the use of RFC 1123 dates, a function
-png_convert_to_rfc1123(png_timep) is provided to convert from PNG
-time to an RFC 1123 format string.
-
-Writing unknown chunks
-
-You can use the png_set_unknown_chunks function to queue up chunks
-for writing. You give it a chunk name, raw data, and a size; that's
-all there is to it. The chunks will be written by the next following
-png_write_info_before_PLTE, png_write_info, or png_write_end function.
-Any chunks previously read into the info structure's unknown-chunk
-list will also be written out in a sequence that satisfies the PNG
-specification's ordering rules.
-
-The high-level write interface
-
-At this point there are two ways to proceed; through the high-level
-write interface, or through a sequence of low-level write operations.
-You can use the high-level interface if your image data is present
-in the info structure. All defined output
-transformations are permitted, enabled by the following masks.
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_PACKING Pack 1, 2 and 4-bit samples
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_STRIP_FILLER Strip out filler
- bytes (deprecated).
- PNG_TRANSFORM_STRIP_FILLER_BEFORE Strip out leading
- filler bytes
- PNG_TRANSFORM_STRIP_FILLER_AFTER Strip out trailing
- filler bytes
-
-If you have valid image data in the info structure (you can use
-png_set_rows() to put image data in the info structure), simply do this:
-
- png_write_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some set of
-transformation flags. This call is equivalent to png_write_info(),
-followed the set of transformations indicated by the transform mask,
-then png_write_image(), and finally png_write_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future output transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_write_png().
-
-The low-level write interface
-
-If you are going the low-level route instead, you are now ready to
-write all the file information up to the actual image data. You do
-this with a call to png_write_info().
-
- png_write_info(png_ptr, info_ptr);
-
-Note that there is one transformation you may need to do before
-png_write_info(). In PNG files, the alpha channel in an image is the
-level of opacity. If your data is supplied as a level of transparency,
-you can invert the alpha channel before you write it, so that 0 is
-fully transparent and 255 (in 8-bit or paletted images) or 65535
-(in 16-bit images) is fully opaque, with
-
- png_set_invert_alpha(png_ptr);
-
-This must appear before png_write_info() instead of later with the
-other transformations because in the case of paletted images the tRNS
-chunk data has to be inverted before the tRNS chunk is written. If
-your image is not a paletted image, the tRNS data (which in such cases
-represents a single color to be rendered as transparent) won't need to
-be changed, and you can safely do this transformation after your
-png_write_info() call.
-
-If you need to write a private chunk that you want to appear before
-the PLTE chunk when PLTE is present, you can write the PNG info in
-two steps, and insert code to write your own chunk between them:
-
- png_write_info_before_PLTE(png_ptr, info_ptr);
- png_set_unknown_chunks(png_ptr, info_ptr, ...);
- png_write_info(png_ptr, info_ptr);
-
-After you've written the file information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code tells
-the library to strip input data that has 4 or 8 bytes per pixel down
-to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2
-bytes per pixel).
-
- png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE);
-
-where the 0 is unused, and the location is either PNG_FILLER_BEFORE or
-PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel
-is stored XRGB or RGBX.
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit files.
-If the data is supplied at 1 pixel per byte, use this code, which will
-correctly pack the pixels into a single byte:
-
- png_set_packing(png_ptr);
-
-PNG files reduce possible bit depths to 1, 2, 4, 8, and 16. If your
-data is of another bit depth, you can write an sBIT chunk into the
-file so that decoders can recover the original data if desired.
-
- /* Set the true bit depth of the image data */
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- sig_bit.red = true_bit_depth;
- sig_bit.green = true_bit_depth;
- sig_bit.blue = true_bit_depth;
- }
- else
- {
- sig_bit.gray = true_bit_depth;
- }
- if (color_type & PNG_COLOR_MASK_ALPHA)
- {
- sig_bit.alpha = true_bit_depth;
- }
-
- png_set_sBIT(png_ptr, info_ptr, &sig_bit);
-
-If the data is stored in the row buffer in a bit depth other than
-one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG),
-this will scale the values to appear to be the correct bit depth as
-is required by PNG.
-
- png_set_shift(png_ptr, &sig_bit);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code would be used if they are
-supplied the other way (little-endian, i.e. least significant bits
-first, the way PCs store them):
-
- if (bit_depth > 8)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-PNG files store 3 color pixels in red, green, blue order. This code
-would be used if they are supplied as blue, green, red:
-
- png_set_bgr(png_ptr);
-
-PNG files describe monochrome as black being zero and white being
-one. This code would be used if the pixels are supplied with this reversed
-(black being one and white being zero):
-
- png_set_invert_mono(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_write_user_transform_fn(png_ptr,
- write_transform_fn);
-
-You must supply the function
-
- void write_transform_fn(png_ptr ptr, row_info_ptr
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-before any of the other transformations are processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function.
-
- png_set_user_transform_info(png_ptr, user_ptr, 0, 0);
-
-The user_channels and user_depth parameters of this function are ignored
-when writing; you can set them to zero as shown.
-
-You can retrieve the pointer via the function png_get_user_transform_ptr().
-For example:
-
- voidp write_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-It is possible to have libpng flush any pending output, either manually,
-or automatically after a certain number of lines have been written. To
-flush the output stream a single time call:
-
- png_write_flush(png_ptr);
-
-and to have libpng flush the output stream periodically after a certain
-number of scanlines have been written, call:
-
- png_set_flush(png_ptr, nrows);
-
-Note that the distance between rows is from the last time png_write_flush()
-was called, or the first row of the image if it has never been called.
-So if you write 50 lines, and then png_set_flush 25, it will flush the
-output on the next scanline, and every 25 lines thereafter, unless
-png_write_flush() is called before 25 more lines have been written.
-If nrows is too small (less than about 10 lines for a 640 pixel wide
-RGB image) the image compression may decrease noticeably (although this
-may be acceptable for real-time applications). Infrequent flushing will
-only degrade the compression performance by a few percent over images
-that do not use flushing.
-
-Writing the image data
-
-That's it for the transformations. Now you can write the image data.
-The simplest way to do this is in one function call. If you have the
-whole image in memory, you can just call png_write_image() and libpng
-will write the image. You will need to pass in an array of pointers to
-each row. This function automatically handles interlacing, so you don't
-need to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_write_rows().
-
- png_write_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_byte *row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to write the whole image at once, you can
-use png_write_rows() instead. If the file is not interlaced,
-this is simple:
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-row_pointers is the same as in the png_write_image() call.
-
-If you are just writing one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
-
- png_write_row(png_ptr, row_pointer);
-
-When the file is interlaced, things can get a good deal more complicated.
-The only currently (as of the PNG Specification version 1.2, dated July
-1999) defined interlacing scheme for PNG files is the "Adam7" interlace
-scheme, that breaks down an image into seven smaller images of varying
-size. libpng will build these images for you, or you can do them
-yourself. If you want to build them yourself, see the PNG specification
-for details of which pixels to write when.
-
-If you don't want libpng to handle the interlacing details, just
-use png_set_interlace_handling() and call png_write_rows() the
-correct number of times to write all seven sub-images.
-
-If you want libpng to build the sub-images, call this before you start
-writing any rows:
-
- number_of_passes =
- png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this is seven,
-but may change if another interlace type is added.
-
-Then write the complete image number_of_passes times.
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-As some of these rows are not used, and thus return immediately, you may
-want to read about interlacing in the PNG specification, and only update
-the rows that are actually used.
-
-Finishing a sequential write
-
-After you are finished writing the image, you should finish writing
-the file. If you are interested in writing comments or time, you should
-pass an appropriately filled png_info pointer. If you are not interested,
-you can pass NULL.
-
- png_write_end(png_ptr, info_ptr);
-
-When you are done, you can free all memory used by libpng like this:
-
- png_destroy_write_struct(&png_ptr, &info_ptr);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-If you allocated data such as a palette that you passed in to libpng
-with png_set_*, you must not free it until just before the call to
-png_destroy_write_struct().
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-For example, to transfer responsibility for some data from a read structure
-to a write structure, you could use
-
- png_data_freer(read_ptr, read_info_ptr,
- PNG_USER_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
- png_data_freer(write_ptr, write_info_ptr,
- PNG_DESTROY_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
-
-thereby briefly reassigning responsibility for freeing to the user but
-immediately afterwards reassigning it once more to the write_destroy
-function. Having done this, it would then be safe to destroy the read
-structure and continue to use the PLTE, tRNS, and hIST data in the write
-structure.
-
-This function only affects data that has already been allocated.
-You can call this function before calling after the png_set_*() functions
-to control whether the user or png_destroy_*() is supposed to free the data.
-When the user assumes responsibility for libpng-allocated data, the
-application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-For a more compact example of writing a PNG image, see the file example.c.
-
-V. Modifying/Customizing libpng:
-
-There are two issues here. The first is changing how libpng does
-standard things like memory allocation, input/output, and error handling.
-The second deals with more complicated things like adding new chunks,
-adding new transformations, and generally changing how libpng works.
-Both of those are compile-time issues; that is, they are generally
-determined at the time the code is written, and there is rarely a need
-to provide the user with a means of changing them.
-
-Memory allocation, input/output, and error handling
-
-All of the memory allocation, input/output, and error handling in libpng
-goes through callbacks that are user-settable. The default routines are
-in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively. To change
-these functions, call the appropriate png_set_*_fn() function.
-
-Memory allocation is done through the functions png_malloc(), png_calloc(),
-and png_free(). These currently just call the standard C functions.
-png_calloc() calls png_malloc() and then png_memset() to clear the newly
-allocated memory to zero. If your pointers can't access more then 64K
-at a time, you will want to set MAXSEG_64K in zlib.h. Since it is
-unlikely that the method of handling memory allocation on a platform
-will change between applications, these functions must be modified in
-the library at compile time. If you prefer to use a different method
-of allocating and freeing data, you can use png_create_read_struct_2() or
-png_create_write_struct_2() to register your own functions as described
-above. These functions also provide a void pointer that can be retrieved
-via
-
- mem_ptr=png_get_mem_ptr(png_ptr);
-
-Your replacement memory functions must have prototypes as follows:
-
- png_voidp malloc_fn(png_structp png_ptr,
- png_alloc_size_t size);
- void free_fn(png_structp png_ptr, png_voidp ptr);
-
-Your malloc_fn() must return NULL in case of failure. The png_malloc()
-function will normally call png_error() if it receives a NULL from the
-system memory allocator or from your replacement malloc_fn().
-
-Your free_fn() will never be called with a NULL ptr, since libpng's
-png_free() checks for NULL before calling free_fn().
-
-Input/Output in libpng is done through png_read() and png_write(),
-which currently just call fread() and fwrite(). The FILE * is stored in
-png_struct and is initialized via png_init_io(). If you wish to change
-the method of I/O, the library supplies callbacks that you can set
-through the function png_set_read_fn() and png_set_write_fn() at run
-time, instead of calling the png_init_io() function. These functions
-also provide a void pointer that can be retrieved via the function
-png_get_io_ptr(). For example:
-
- png_set_read_fn(png_structp read_ptr,
- voidp read_io_ptr, png_rw_ptr read_data_fn)
-
- png_set_write_fn(png_structp write_ptr,
- voidp write_io_ptr, png_rw_ptr write_data_fn,
- png_flush_ptr output_flush_fn);
-
- voidp read_io_ptr = png_get_io_ptr(read_ptr);
- voidp write_io_ptr = png_get_io_ptr(write_ptr);
-
-The replacement I/O functions must have prototypes as follows:
-
- void user_read_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_write_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_flush_data(png_structp png_ptr);
-
-The user_read_data() function is responsible for detecting and
-handling end-of-data errors.
-
-Supplying NULL for the read, write, or flush functions sets them back
-to using the default C stream functions, which expect the io_ptr to
-point to a standard *FILE structure. It is probably a mistake
-to use NULL for one of write_data_fn and output_flush_fn but not both
-of them, unless you have built libpng with PNG_NO_WRITE_FLUSH defined.
-It is an error to read from a write stream, and vice versa.
-
-Error handling in libpng is done through png_error() and png_warning().
-Errors handled through png_error() are fatal, meaning that png_error()
-should never return to its caller. Currently, this is handled via
-setjmp() and longjmp() (unless you have compiled libpng with
-PNG_NO_SETJMP, in which case it is handled via PNG_ABORT()),
-but you could change this to do things like exit() if you should wish,
-as long as your function does not return.
-
-On non-fatal errors, png_warning() is called
-to print a warning message, and then control returns to the calling code.
-By default png_error() and png_warning() print a message on stderr via
-fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined
-(because you don't want the messages) or PNG_NO_STDIO defined (because
-fprintf() isn't available). If you wish to change the behavior of the error
-functions, you will need to set up your own message callbacks. These
-functions are normally supplied at the time that the png_struct is created.
-It is also possible to redirect errors and warnings to your own replacement
-functions after png_create_*_struct() has been called by calling:
-
- png_set_error_fn(png_structp png_ptr,
- png_voidp error_ptr, png_error_ptr error_fn,
- png_error_ptr warning_fn);
-
- png_voidp error_ptr = png_get_error_ptr(png_ptr);
-
-If NULL is supplied for either error_fn or warning_fn, then the libpng
-default function will be used, calling fprintf() and/or longjmp() if a
-problem is encountered. The replacement error functions should have
-parameters as follows:
-
- void user_error_fn(png_structp png_ptr,
- png_const_charp error_msg);
- void user_warning_fn(png_structp png_ptr,
- png_const_charp warning_msg);
-
-The motivation behind using setjmp() and longjmp() is the C++ throw and
-catch exception handling methods. This makes the code much easier to write,
-as there is no need to check every return code of every function call.
-However, there are some uncertainties about the status of local variables
-after a longjmp, so the user may want to be careful about doing anything
-after setjmp returns non-zero besides returning itself. Consult your
-compiler documentation for more details. For an alternative approach, you
-may wish to use the "cexcept" facility (see http://cexcept.sourceforge.net).
-
-Custom chunks
-
-If you need to read or write custom chunks, you may need to get deeper
-into the libpng code. The library now has mechanisms for storing
-and writing chunks of unknown type; you can even declare callbacks
-for custom chunks. However, this may not be good enough if the
-library code itself needs to know about interactions between your
-chunk and existing `intrinsic' chunks.
-
-If you need to write a new intrinsic chunk, first read the PNG
-specification. Acquire a first level of understanding of how it works.
-Pay particular attention to the sections that describe chunk names,
-and look at how other chunks were designed, so you can do things
-similarly. Second, check out the sections of libpng that read and
-write chunks. Try to find a chunk that is similar to yours and use
-it as a template. More details can be found in the comments inside
-the code. It is best to handle unknown chunks in a generic method,
-via callback functions, instead of by modifying libpng functions.
-
-If you wish to write your own transformation for the data, look through
-the part of the code that does the transformations, and check out some of
-the simpler ones to get an idea of how they work. Try to find a similar
-transformation to the one you want to add and copy off of it. More details
-can be found in the comments inside the code itself.
-
-Configuring for 16 bit platforms
-
-You will want to look into zconf.h to tell zlib (and thus libpng) that
-it cannot allocate more then 64K at a time. Even if you can, the memory
-won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
-
-Configuring for DOS
-
-For DOS users who only have access to the lower 640K, you will
-have to limit zlib's memory usage via a png_set_compression_mem_level()
-call. See zlib.h or zconf.h in the zlib library for more information.
-
-Configuring for Medium Model
-
-Libpng's support for medium model has been tested on most of the popular
-compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
-defined, and FAR gets defined to far in pngconf.h, and you should be
-all set. Everything in the library (except for zlib's structure) is
-expecting far data. You must use the typedefs with the p or pp on
-the end for pointers (or at least look at them and be careful). Make
-note that the rows of data are defined as png_bytepp, which is an
-unsigned char far * far *.
-
-Configuring for gui/windowing platforms:
-
-You will need to write new error and warning functions that use the GUI
-interface, as described previously, and set them to be the error and
-warning functions at the time that png_create_*_struct() is called,
-in order to have them available during the structure initialization.
-They can be changed later via png_set_error_fn(). On some compilers,
-you may also have to change the memory allocators (png_malloc, etc.).
-
-Configuring for compiler xxx:
-
-All includes for libpng are in pngconf.h. If you need to add, change
-or delete an include, this is the place to do it.
-The includes that are not needed outside libpng are placed in pngpriv.h,
-which is only used by the routines inside libpng itself.
-The files in libpng proper only include pngpriv.h and png.h, which
-in turn includes pngconf.h.
-
-Configuring zlib:
-
-There are special functions to configure the compression. Perhaps the
-most useful one changes the compression level, which currently uses
-input compression values in the range 0 - 9. The library normally
-uses the default compression level (Z_DEFAULT_COMPRESSION = 6). Tests
-have shown that for a large majority of images, compression values in
-the range 3-6 compress nearly as well as higher levels, and do so much
-faster. For online applications it may be desirable to have maximum speed
-(Z_BEST_SPEED = 1). With versions of zlib after v0.99, you can also
-specify no compression (Z_NO_COMPRESSION = 0), but this would create
-files larger than just storing the raw bitmap. You can specify the
-compression level by calling:
-
- png_set_compression_level(png_ptr, level);
-
-Another useful one is to reduce the memory level used by the library.
-The memory level defaults to 8, but it can be lowered if you are
-short on memory (running DOS, for example, where you only have 640K).
-Note that the memory level does have an effect on compression; among
-other things, lower levels will result in sections of incompressible
-data being emitted in smaller stored blocks, with a correspondingly
-larger relative overhead of up to 15% in the worst case.
-
- png_set_compression_mem_level(png_ptr, level);
-
-The other functions are for configuring zlib. They are not recommended
-for normal use and may result in writing an invalid PNG file. See
-zlib.h for more information on what these mean.
-
- png_set_compression_strategy(png_ptr,
- strategy);
- png_set_compression_window_bits(png_ptr,
- window_bits);
- png_set_compression_method(png_ptr, method);
- png_set_compression_buffer_size(png_ptr, size);
-
-Controlling row filtering
-
-If you want to control whether libpng uses filtering or not, which
-filters are used, and how it goes about picking row filters, you
-can call one of these functions. The selection and configuration
-of row filters can have a significant impact on the size and
-encoding speed and a somewhat lesser impact on the decoding speed
-of an image. Filtering is enabled by default for RGB and grayscale
-images (with and without alpha), but not for paletted images nor
-for any images with bit depths less than 8 bits/pixel.
-
-The 'method' parameter sets the main filtering method, which is
-currently only '0' in the PNG 1.2 specification. The 'filters'
-parameter sets which filter(s), if any, should be used for each
-scanline. Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS
-to turn filtering on and off, respectively.
-
-Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB,
-PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise
-ORed together with '|' to specify one or more filters to use.
-These filters are described in more detail in the PNG specification.
-If you intend to change the filter type during the course of writing
-the image, you should start with flags set for all of the filters
-you intend to use so that libpng can initialize its internal
-structures appropriately for all of the filter types. (Note that this
-means the first row must always be adaptively filtered, because libpng
-currently does not allocate the filter buffers until png_write_row()
-is called for the first time.)
-
- filters = PNG_FILTER_NONE | PNG_FILTER_SUB
- PNG_FILTER_UP | PNG_FILTER_AVG |
- PNG_FILTER_PAETH | PNG_ALL_FILTERS;
-
- png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE,
- filters);
- The second parameter can also be
- PNG_INTRAPIXEL_DIFFERENCING if you are
- writing a PNG to be embedded in a MNG
- datastream. This parameter must be the
- same as the value of filter_method used
- in png_set_IHDR().
-
-It is also possible to influence how libpng chooses from among the
-available filters. This is done in one or both of two ways - by
-telling it how important it is to keep the same filter for successive
-rows, and by telling it the relative computational costs of the filters.
-
- double weights[3] = {1.5, 1.3, 1.1},
- costs[PNG_FILTER_VALUE_LAST] =
- {1.0, 1.3, 1.3, 1.5, 1.7};
-
- png_set_filter_heuristics(png_ptr,
- PNG_FILTER_HEURISTIC_WEIGHTED, 3,
- weights, costs);
-
-The weights are multiplying factors that indicate to libpng that the
-row filter should be the same for successive rows unless another row filter
-is that many times better than the previous filter. In the above example,
-if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a
-"sum of absolute differences" 1.5 x 1.3 times higher than other filters
-and still be chosen, while the NONE filter could have a sum 1.1 times
-higher than other filters and still be chosen. Unspecified weights are
-taken to be 1.0, and the specified weights should probably be declining
-like those above in order to emphasize recent filters over older filters.
-
-The filter costs specify for each filter type a relative decoding cost
-to be considered when selecting row filters. This means that filters
-with higher costs are less likely to be chosen over filters with lower
-costs, unless their "sum of absolute differences" is that much smaller.
-The costs do not necessarily reflect the exact computational speeds of
-the various filters, since this would unduly influence the final image
-size.
-
-Note that the numbers above were invented purely for this example and
-are given only to help explain the function usage. Little testing has
-been done to find optimum values for either the costs or the weights.
-
-Removing unwanted object code
-
-There are a bunch of #define's in pngconf.h that control what parts of
-libpng are compiled. All the defines end in _SUPPORTED. If you are
-never going to use a capability, you can change the #define to #undef
-before recompiling libpng and save yourself code and data space, or
-you can turn off individual capabilities with defines that begin with
-PNG_NO_.
-
-You can also turn all of the transforms and ancillary chunk capabilities
-off en masse with compiler directives that define
-PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
-or all four,
-along with directives to turn on any of the capabilities that you do
-want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the extra
-transformations but still leave the library fully capable of reading
-and writing PNG files with all known public chunks. Use of the
-PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
-that is incapable of reading or writing ancillary chunks. If you are
-not using the progressive reading capability, you can turn that off
-with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
-capability, which you'll still have).
-
-All the reading and writing specific code are in separate files, so the
-linker should only grab the files it needs. However, if you want to
-make sure, or if you are building a stand alone library, all the
-reading files start with pngr and all the writing files start with
-pngw. The files that don't match either (like png.c, pngtrans.c, etc.)
-are used for both reading and writing, and always need to be included.
-The progressive reader is in pngpread.c
-
-If you are creating or distributing a dynamically linked library (a .so
-or DLL file), you should not remove or disable any parts of the library,
-as this will cause applications linked with different versions of the
-library to fail if they call functions not available in your library.
-The size of the library itself should not be an issue, because only
-those sections that are actually used will be loaded into memory.
-
-Requesting debug printout
-
-The macro definition PNG_DEBUG can be used to request debugging
-printout. Set it to an integer value in the range 0 to 3. Higher
-numbers result in increasing amounts of debugging information. The
-information is printed to the "stderr" file, unless another file
-name is specified in the PNG_DEBUG_FILE macro definition.
-
-When PNG_DEBUG > 0, the following functions (macros) become available:
-
- png_debug(level, message)
- png_debug1(level, message, p1)
- png_debug2(level, message, p1, p2)
-
-in which "level" is compared to PNG_DEBUG to decide whether to print
-the message, "message" is the formatted string to be printed,
-and p1 and p2 are parameters that are to be embedded in the string
-according to printf-style formatting directives. For example,
-
- png_debug1(2, "foo=%d\n", foo);
-
-is expanded to
-
- if(PNG_DEBUG > 2)
- fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo);
-
-When PNG_DEBUG is defined but is zero, the macros aren't defined, but you
-can still use PNG_DEBUG to control your own debugging:
-
- #ifdef PNG_DEBUG
- fprintf(stderr, ...
- #endif
-
-When PNG_DEBUG = 1, the macros are defined, but only png_debug statements
-having level = 0 will be printed. There aren't any such statements in
-this version of libpng, but if you insert some they will be printed.
-
-VI. MNG support
-
-The MNG specification (available at http://www.libpng.org/pub/mng) allows
-certain extensions to PNG for PNG images that are embedded in MNG datastreams.
-Libpng can support some of these extensions. To enable them, use the
-png_permit_mng_features() function:
-
- feature_set = png_permit_mng_features(png_ptr, mask)
- mask is a png_uint_32 containing the bitwise OR of the
- features you want to enable. These include
- PNG_FLAG_MNG_EMPTY_PLTE
- PNG_FLAG_MNG_FILTER_64
- PNG_ALL_MNG_FEATURES
- feature_set is a png_uint_32 that is the bitwise AND of
- your mask with the set of MNG features that is
- supported by the version of libpng that you are using.
-
-It is an error to use this function when reading or writing a standalone
-PNG file with the PNG 8-byte signature. The PNG datastream must be wrapped
-in a MNG datastream. As a minimum, it must have the MNG 8-byte signature
-and the MHDR and MEND chunks. Libpng does not provide support for these
-or any other MNG chunks; your application must provide its own support for
-them. You may wish to consider using libmng (available at
-http://www.libmng.com) instead.
-
-VII. Changes to Libpng from version 0.88
-
-It should be noted that versions of libpng later than 0.96 are not
-distributed by the original libpng author, Guy Schalnat, nor by
-Andreas Dilger, who had taken over from Guy during 1996 and 1997, and
-distributed versions 0.89 through 0.96, but rather by another member
-of the original PNG Group, Glenn Randers-Pehrson. Guy and Andreas are
-still alive and well, but they have moved on to other things.
-
-The old libpng functions png_read_init(), png_write_init(),
-png_info_init(), png_read_destroy(), and png_write_destroy() have been
-moved to PNG_INTERNAL in version 0.95 to discourage their use. These
-functions will be removed from libpng version 2.0.0.
-
-The preferred method of creating and initializing the libpng structures is
-via the png_create_read_struct(), png_create_write_struct(), and
-png_create_info_struct() because they isolate the size of the structures
-from the application, allow version error checking, and also allow the
-use of custom error handling routines during the initialization, which
-the old functions do not. The functions png_read_destroy() and
-png_write_destroy() do not actually free the memory that libpng
-allocated for these structs, but just reset the data structures, so they
-can be used instead of png_destroy_read_struct() and
-png_destroy_write_struct() if you feel there is too much system overhead
-allocating and freeing the png_struct for each image read.
-
-Setting the error callbacks via png_set_message_fn() before
-png_read_init() as was suggested in libpng-0.88 is no longer supported
-because this caused applications that do not use custom error functions
-to fail if the png_ptr was not initialized to zero. It is still possible
-to set the error callbacks AFTER png_read_init(), or to change them with
-png_set_error_fn(), which is essentially the same function, but with a new
-name to force compilation errors with applications that try to use the old
-method.
-
-Starting with version 1.0.7, you can find out which version of the library
-you are using at run-time:
-
- png_uint_32 libpng_vn = png_access_version_number();
-
-The number libpng_vn is constructed from the major version, minor
-version with leading zero, and release number with leading zero,
-(e.g., libpng_vn for version 1.0.7 is 10007).
-
-You can also check which version of png.h you used when compiling your
-application:
-
- png_uint_32 application_vn = PNG_LIBPNG_VER;
-
-VIII. Changes to Libpng from version 1.0.x to 1.2.x
-
-Support for user memory management was enabled by default. To
-accomplish this, the functions png_create_read_struct_2(),
-png_create_write_struct_2(), png_set_mem_fn(), png_get_mem_ptr(),
-png_malloc_default(), and png_free_default() were added.
-
-Support for the iTXt chunk has been enabled by default as of
-version 1.2.41.
-
-Support for certain MNG features was enabled.
-
-Support for numbered error messages was added. However, we never got
-around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was added (Note: the prototype for this
-function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE
-builds of libpng-1.2.15. It was restored in libpng-1.2.36).
-
-The png_malloc_warn() function was added at libpng-1.2.3. This issues
-a png_warning and returns NULL instead of aborting when it fails to
-acquire the requested memory allocation.
-
-Support for setting user limits on image width and height was enabled
-by default. The functions png_set_user_limits(), png_get_user_width_max(),
-and png_get_user_height_max() were added at libpng-1.2.6.
-
-The png_set_add_alpha() function was added at libpng-1.2.7.
-
-The function png_set_expand_gray_1_2_4_to_8() was added at libpng-1.2.9.
-Unlike png_set_gray_1_2_4_to_8(), the new function does not expand the
-tRNS chunk to alpha. The png_set_gray_1_2_4_to_8() function is
-deprecated.
-
-A number of macro definitions in support of runtime selection of
-assembler code features (especially Intel MMX code support) were
-added at libpng-1.2.0:
-
- PNG_ASM_FLAG_MMX_SUPPORT_COMPILED
- PNG_ASM_FLAG_MMX_SUPPORT_IN_CPU
- PNG_ASM_FLAG_MMX_READ_COMBINE_ROW
- PNG_ASM_FLAG_MMX_READ_INTERLACE
- PNG_ASM_FLAG_MMX_READ_FILTER_SUB
- PNG_ASM_FLAG_MMX_READ_FILTER_UP
- PNG_ASM_FLAG_MMX_READ_FILTER_AVG
- PNG_ASM_FLAG_MMX_READ_FILTER_PAETH
- PNG_ASM_FLAGS_INITIALIZED
- PNG_MMX_READ_FLAGS
- PNG_MMX_FLAGS
- PNG_MMX_WRITE_FLAGS
- PNG_MMX_FLAGS
-
-We added the following functions in support of runtime
-selection of assembler code features:
-
- png_get_mmx_flagmask()
- png_set_mmx_thresholds()
- png_get_asm_flags()
- png_get_mmx_bitdepth_threshold()
- png_get_mmx_rowbytes_threshold()
- png_set_asm_flags()
-
-We replaced all of these functions with simple stubs in libpng-1.2.20,
-when the Intel assembler code was removed due to a licensing issue.
-
-These macros are deprecated:
-
- PNG_READ_TRANSFORMS_NOT_SUPPORTED
- PNG_PROGRESSIVE_READ_NOT_SUPPORTED
- PNG_NO_SEQUENTIAL_READ_SUPPORTED
- PNG_WRITE_TRANSFORMS_NOT_SUPPORTED
- PNG_READ_ANCILLARY_CHUNKS_NOT_SUPPORTED
- PNG_WRITE_ANCILLARY_CHUNKS_NOT_SUPPORTED
-
-They have been replaced, respectively, by:
-
- PNG_NO_READ_TRANSFORMS
- PNG_NO_PROGRESSIVE_READ
- PNG_NO_SEQUENTIAL_READ
- PNG_NO_WRITE_TRANSFORMS
- PNG_NO_READ_ANCILLARY_CHUNKS
- PNG_NO_WRITE_ANCILLARY_CHUNKS
-
-PNG_MAX_UINT was replaced with PNG_UINT_31_MAX. It has been
-deprecated since libpng-1.0.16 and libpng-1.2.6.
-
-The function
- png_check_sig(sig, num)
-was replaced with
- !png_sig_cmp(sig, 0, num)
-It has been deprecated since libpng-0.90.
-
-The function
- png_set_gray_1_2_4_to_8()
-which also expands tRNS to alpha was replaced with
- png_set_expand_gray_1_2_4_to_8()
-which does not. It has been deprecated since libpng-1.0.18 and 1.2.9.
-
-IX. Changes to Libpng from version 1.0.x/1.2.x to 1.4.x
-
-Private libpng prototypes and macro definitions were moved from
-png.h and pngconf.h into a new pngpriv.h header file.
-
-Functions png_set_benign_errors(), png_benign_error(), and
-png_chunk_benign_error() were added.
-
-Support for setting the maximum amount of memory that the application
-will allocate for reading chunks was added, as a security measure.
-The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
-were added to the library.
-
-We implemented support for I/O states by adding png_ptr member io_state
-and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
-
-We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
-input transforms.
-
-Checking for and reporting of errors in the IHDR chunk is more thorough.
-
-Support for global arrays was removed, to improve thread safety.
-
-Some obsolete/deprecated macros and functions have been removed.
-
-Typecasted NULL definitions such as
- #define png_voidp_NULL (png_voidp)NULL
-were eliminated. If you used these in your application, just use
-NULL instead.
-
-The png_struct and info_struct members "trans" and "trans_values" were
-changed to "trans_alpha" and "trans_color", respectively.
-
-The obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles
-were removed.
-
-The PNG_1_0_X and PNG_1_2_X macros were eliminated.
-
-The PNG_LEGACY_SUPPORTED macro was eliminated.
-
-Many WIN32_WCE #ifdefs were removed.
-
-The functions png_read_init(info_ptr), png_write_init(info_ptr),
-png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
-have been removed. They have been deprecated since libpng-0.95.
-
-The png_permit_empty_plte() was removed. It has been deprecated
-since libpng-1.0.9. Use png_permit_mng_features() instead.
-
-We removed the obsolete stub functions png_get_mmx_flagmask(),
-png_set_mmx_thresholds(), png_get_asm_flags(),
-png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
-png_set_asm_flags(), and png_mmx_supported()
-
-We removed the obsolete png_check_sig(), png_memcpy_check(), and
-png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(),
-and png_memset(), respectively.
-
-The function png_set_gray_1_2_4_to_8() was removed. It has been
-deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
-png_set_expand_gray_1_2_4_to_8() because the former function also
-expanded palette images.
-
-We changed the prototype for png_malloc() from
- png_malloc(png_structp png_ptr, png_uint_32 size)
-to
- png_malloc(png_structp png_ptr, png_alloc_size_t size)
-
-This also applies to the prototype for the user replacement malloc_fn().
-
-The png_calloc() function was added and is used in place of
-of "png_malloc(); png_memset();" except in the case in png_read_png()
-where the array consists of pointers; in this case a "for" loop is used
-after the png_malloc() to set the pointers to NULL, to give robust.
-behavior in case the application runs out of memory part-way through
-the process.
-
-We changed the prototypes of png_get_compression_buffer_size() and
-png_set_compression_buffer_size() to work with png_size_t instead of
-png_uint_32.
-
-Support for numbered error messages was removed by default, since we
-never got around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was removed from the library by default.
-
-The png_zalloc() and png_zfree() functions are no longer exported.
-The png_zalloc() function no longer zeroes out the memory that it
-allocates.
-
-Support for dithering was disabled by default in libpng-1.4.0, because
-been well tested and doesn't actually "dither". The code was not
-removed, however, and could be enabled by building libpng with
-PNG_READ_DITHER_SUPPORTED defined. In libpng-1.4.2, this support
-was reenabled, but the function was renamed png_set_quantize() to
-reflect more accurately what it actually does. At the same time,
-the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros were also renamed to
-PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
-
-We removed the trailing '.' from the warning and error messages.
-
-X. Detecting libpng
-
-The png_get_io_ptr() function has been present since libpng-0.88, has never
-changed, and is unaffected by conditional compilation macros. It is the
-best choice for use in configure scripts for detecting the presence of any
-libpng version since 0.88. In an autoconf "configure.in" you could use
-
- AC_CHECK_LIB(png, png_get_io_ptr, ...
-
-XI. Source code repository
-
-Since about February 2009, version 1.2.34, libpng has been under "git" source
-control. The git repository was built from old libpng-x.y.z.tar.gz files
-going back to version 0.70. You can access the git repository (read only)
-at
-
- git://libpng.git.sourceforge.net/gitroot/libpng
-
-or you can browse it via "gitweb" at
-
- http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
-
-Patches can be sent to glennrp at users.sourceforge.net or to
-png-mng-implement at lists.sourceforge.net or you can upload them to
-the libpng bug tracker at
-
- http://libpng.sourceforge.net
-
-XII. Coding style
-
-Our coding style is similar to the "Allman" style, with curly
-braces on separate lines:
-
- if (condition)
- {
- action;
- }
-
- else if (another condition)
- {
- another action;
- }
-
-The braces can be omitted from simple one-line actions:
-
- if (condition)
- return (0);
-
-We use 3-space indentation, except for continued statements which
-are usually indented the same as the first line of the statement
-plus four more spaces.
-
-For macro definitions we use 2-space indentation, always leaving the "#"
-in the first column.
-
- #ifndef PNG_NO_FEATURE
- # ifndef PNG_FEATURE_SUPPORTED
- # define PNG_FEATURE_SUPPORTED
- # endif
- #endif
-
-Comments appear with the leading "/*" at the same indentation as
-the statement that follows the comment:
-
- /* Single-line comment */
- statement;
-
- /* This is a multiple-line
- * comment.
- */
- statement;
-
-Very short comments can be placed after the end of the statement
-to which they pertain:
-
- statement; /* comment */
-
-We don't use C++ style ("//") comments. We have, however,
-used them in the past in some now-abandoned MMX assembler
-code.
-
-Functions and their curly braces are not indented, and
-exported functions are marked with PNGAPI:
-
- /* This is a public function that is visible to
- * application programers. It does thus-and-so.
- */
- void PNGAPI
- png_exported_function(png_ptr, png_info, foo)
- {
- body;
- }
-
-The prototypes for all exported functions appear in png.h,
-above the comment that says
-
- /* Maintainer: Put new public prototypes here ... */
-
-We mark all non-exported functions with "/* PRIVATE */"":
-
- void /* PRIVATE */
- png_non_exported_function(png_ptr, png_info, foo)
- {
- body;
- }
-
-The prototypes for non-exported functions (except for those in
-pngtest) appear in
-pngpriv.h
-above the comment that says
-
- /* Maintainer: Put new private prototypes here ^ and in libpngpf.3 */
-
-The names of all exported functions and variables begin
-with "png_", and all publicly visible C preprocessor
-macros begin with "PNG_".
-
-We put a space after each comma and after each semicolon
-in "for" statments, and we put spaces before and after each
-C binary operator and after "for" or "while", and before
-"?". We don't put a space between a typecast and the expression
-being cast, nor do we put one between a function name and the
-left parenthesis that follows it:
-
- for (i = 2; i > 0; --i)
- y[i] = a(x) + (int)b;
-
-We prefer #ifdef and #ifndef to #if defined() and if !defined()
-when there is only one macro being tested.
-
-We do not use the TAB character for indentation in the C sources.
-
-Lines do not exceed 80 characters.
-
-Other rules can be inferred by inspecting the libpng source.
-
-XIII. Y2K Compliance in libpng
-
-September 23, 2010
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.4.4 are Y2K compliant. It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has three year fields. One is a 2-byte unsigned integer that
-will hold years up to 65535. The other two hold the date in text
-format, and will hold years up to 9999.
-
-The integer is
- "png_uint_16 year" in png_time_struct.
-
-The strings are
- "png_charp time_buffer" in png_struct and
- "near_time_buffer", which is a local character string in png.c.
-
-There are seven time-related functions:
-
- png_convert_to_rfc_1123() in png.c
- (formerly png_convert_to_rfc_1152() in error)
- png_convert_from_struct_tm() in pngwrite.c, called
- in pngwrite.c
- png_convert_from_time_t() in pngwrite.c
- png_get_tIME() in pngget.c
- png_handle_tIME() in pngrutil.c, called in pngread.c
- png_set_tIME() in pngset.c
- png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment. The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year. There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control. The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant. It contains
-no date-related code.

+ * derived values were recorded in the cHRM chunk;
+ * (red,green,blue,white)x(x,y). This loses one degree of freedom and
+ * therefore an arbitrary ninth value has to be introduced to undo the
+ * original transformations.
+ *
+ * Think of the original end-points as points in (X,Y,Z) space. The
+ * chromaticity values (c) have the property:
+ *
+ * C
+ * c = ---------
+ * X + Y + Z
+ *
+ * For each c (x,y,z) from the corresponding original C (X,Y,Z). Thus the
+ * three chromaticity values (x,y,z) for each end-point obey the
+ * relationship:
+ *
+ * x + y + z = 1
+ *
+ * This describes the plane in (X,Y,Z) space that intersects each axis at the
+ * value 1.0; call this the chromaticity plane. Thus the chromaticity
+ * calculation has scaled each end-point so that it is on the x+y+z=1 plane
+ * and chromaticity is the intersection of the vector from the origin to the
+ * (X,Y,Z) value with the chromaticity plane.
+ *
+ * To fully invert the chromaticity calculation we would need the three
+ * end-point scale factors, (red-scale, green-scale, blue-scale), but these
+ * were not recorded. Instead we calculated the reference white (X,Y,Z) and
+ * recorded the chromaticity of this. The reference white (X,Y,Z) would have
+ * given all three of the scale factors since:
+ *
+ * color-C = color-c * color-scale
+ * white-C = red-C + green-C + blue-C
+ * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+ *
+ * But cHRM records only white-x and white-y, so we have lost the white scale
+ * factor:
+ *
+ * white-C = white-c*white-scale
+ *
+ * To handle this the inverse transformation makes an arbitrary assumption
+ * about white-scale:
+ *
+ * Assume: white-Y = 1.0
+ * Hence: white-scale = 1/white-y
+ * Or: red-Y + green-Y + blue-Y = 1.0
+ *
+ * Notice the last statement of the assumption gives an equation in three of
+ * the nine values we want to calculate. 8 more equations come from the
+ * above routine as summarised at the top above (the chromaticity
+ * calculation):
+ *
+ * Given: color-x = color-X / (color-X + color-Y + color-Z)
+ * Hence: (color-x - 1)*color-X + color.x*color-Y + color.x*color-Z = 0
+ *
+ * This is 9 simultaneous equations in the 9 variables "color-C" and can be
+ * solved by Cramer's rule. Cramer's rule requires calculating 10 9x9 matrix
+ * determinants, however this is not as bad as it seems because only 28 of
+ * the total of 90 terms in the various matrices are non-zero. Nevertheless
+ * Cramer's rule is notoriously numerically unstable because the determinant
+ * calculation involves the difference of large, but similar, numbers. It is
+ * difficult to be sure that the calculation is stable for real world values
+ * and it is certain that it becomes unstable where the end points are close
+ * together.
+ *
+ * So this code uses the perhaps slighly less optimal but more understandable
+ * and totally obvious approach of calculating color-scale.
+ *
+ * This algorithm depends on the precision in white-scale and that is
+ * (1/white-y), so we can immediately see that as white-y approaches 0 the
+ * accuracy inherent in the cHRM chunk drops off substantially.
+ *
+ * libpng arithmetic: a simple invertion of the above equations
+ * ------------------------------------------------------------
+ *
+ * white_scale = 1/white-y
+ * white-X = white-x * white-scale
+ * white-Y = 1.0
+ * white-Z = (1 - white-x - white-y) * white_scale
+ *
+ * white-C = red-C + green-C + blue-C
+ * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+ *
+ * This gives us three equations in (red-scale,green-scale,blue-scale) where
+ * all the coefficients are now known:
+ *
+ * red-x*red-scale + green-x*green-scale + blue-x*blue-scale
+ * = white-x/white-y
+ * red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1
+ * red-z*red-scale + green-z*green-scale + blue-z*blue-scale
+ * = (1 - white-x - white-y)/white-y
+ *
+ * In the last equation color-z is (1 - color-x - color-y) so we can add all
+ * three equations together to get an alternative third:
+ *
+ * red-scale + green-scale + blue-scale = 1/white-y = white-scale
+ *
+ * So now we have a Cramer's rule solution where the determinants are just
+ * 3x3 - far more tractible. Unfortunately 3x3 determinants still involve
+ * multiplication of three coefficients so we can't guarantee to avoid
+ * overflow in the libpng fixed point representation. Using Cramer's rule in
+ * floating point is probably a good choice here, but it's not an option for
+ * fixed point. Instead proceed to simplify the first two equations by
+ * eliminating what is likely to be the largest value, blue-scale:
+ *
+ * blue-scale = white-scale - red-scale - green-scale
+ *
+ * Hence:
+ *
+ * (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale =
+ * (white-x - blue-x)*white-scale
+ *
+ * (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale =
+ * 1 - blue-y*white-scale
+ *
+ * And now we can trivially solve for (red-scale,green-scale):
+ *
+ * green-scale =
+ * (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale
+ * -----------------------------------------------------------
+ * green-x - blue-x
+ *
+ * red-scale =
+ * 1 - blue-y*white-scale - (green-y - blue-y) * green-scale
+ * ---------------------------------------------------------
+ * red-y - blue-y
+ *
+ * Hence:
+ *
+ * red-scale =
+ * ( (green-x - blue-x) * (white-y - blue-y) -
+ * (green-y - blue-y) * (white-x - blue-x) ) / white-y
+ * -------------------------------------------------------------------------
+ * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+ *
+ * green-scale =
+ * ( (red-y - blue-y) * (white-x - blue-x) -
+ * (red-x - blue-x) * (white-y - blue-y) ) / white-y
+ * -------------------------------------------------------------------------
+ * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+ *
+ * Accuracy:
+ * The input values have 5 decimal digits of accuracy. The values are all in
+ * the range 0 < value < 1, so simple products are in the same range but may
+ * need up to 10 decimal digits to preserve the original precision and avoid
+ * underflow. Because we are using a 32-bit signed representation we cannot
+ * match this; the best is a little over 9 decimal digits, less than 10.
+ *
+ * The approach used here is to preserve the maximum precision within the
+ * signed representation. Because the red-scale calculation above uses the
+ * difference between two products of values that must be in the range -1..+1
+ * it is sufficient to divide the product by 7; ceil(100,000/32767*2). The
+ * factor is irrelevant in the calculation because it is applied to both
+ * numerator and denominator.
+ *
+ * Note that the values of the differences of the products of the
+ * chromaticities in the above equations tend to be small, for example for
+ * the sRGB chromaticities they are:
+ *
+ * red numerator: -0.04751
+ * green numerator: -0.08788
+ * denominator: -0.2241 (without white-y multiplication)
+ *
+ * The resultant Y coefficients from the chromaticities of some widely used
+ * color space definitions are (to 15 decimal places):
+ *

+ * that will hold years up to 65535. The other holds the date in text
* format, and will hold years up to 9999.
*
* The integer is
* "png_uint_16 year" in png_time_struct.
*
- * The strings are
- * "png_charp time_buffer" in png_struct and
- * "near_time_buffer", which is a local character string in png.c.
+ * The string is
+ * "png_char time_buffer" in png_struct
*
* There are seven time-related functions:
* png.c: png_convert_to_rfc_1123() in png.c

+/* How the alpha channel is interpreted - this affects how the color channels of

+ * file, is present.
+ *
+ * This has no effect on the way pixels are written into a PNG output
+ * datastream. The color samples in a PNG datastream are never premultiplied
+ * with the alpha samples.
+ *
+ * The default is to return data according to the PNG specification: the alpha
+ * channel is a linear measure of the contribution of the pixel to the
+ * corresponding composited pixel. The gamma encoded color channels must be
+ * scaled according to the contribution and to do this it is necessary to undo
+ * the encoding, scale the color values, perform the composition and reencode
+ * the values. This is the 'PNG' mode.
+ *
+ * The alternative is to 'associate' the alpha with the color information by
+ * storing color channel values that have been scaled by the alpha. The
+ * advantage is that the color channels can be resampled (the image can be
+ * scaled) in this form. The disadvantage is that normal practice is to store
+ * linear, not (gamma) encoded, values and this requires 16-bit channels for
+ * still images rather than the 8-bit channels that are just about sufficient if
+ * gamma encoding is used. In addition all non-transparent pixel values,
+ * including completely opaque ones, must be gamma encoded to produce the final
+ * image. This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
+ * latter being the two common names for associated alpha color channels.)
+ *
+ * Since it is not necessary to perform arithmetic on opaque color values so
+ * long as they are not to be resampled and are in the final color space it is
+ * possible to optimize the handling of alpha by storing the opaque pixels in
+ * the PNG format (adjusted for the output color space) while storing partially
+ * opaque pixels in the standard, linear, format. The accuracy required for
+ * standard alpha composition is relatively low, because the pixels are
+ * isolated, therefore typically the accuracy loss in storing 8-bit linear
+ * values is acceptable. (This is not true if the alpha channel is used to
+ * simulate transparency over large areas - use 16 bits or the PNG mode in
+ * this case!) This is the 'OPTIMIZED' mode. For this mode a pixel is
+ * treated as opaque only if the alpha value is equal to the maximum value.
+ *
+ * The final choice is to gamma encode the alpha channel as well. This is
+ * broken because, in practice, no implementation that uses this choice
+ * correctly undoes the encoding before handling alpha composition. Use this
+ * choice only if other serious errors in the software or hardware you use
+ * mandate it; the typical serious error is for dark halos to appear around
+ * opaque areas of the composited PNG image because of arithmetic overflow.
+ *
+ * The API function png_set_alpha_mode specifies which of these choices to use
+ * with an enumerated 'mode' value and the gamma of the required output:

+/* The output_gamma value is a screen gamma in libpng terminology: it expresses
+ * how to decode the output values, not how they are encoded. The values used
+ * correspond to the normal numbers used to describe the overall gamma of a
+ * computer display system; for example 2.2 for an sRGB conformant system. The
+ * values are scaled by 100000 in the _fixed version of the API (so 220000 for
+ * sRGB.)
+ *
+ * The inverse of the value is always used to provide a default for the PNG file
+ * encoding if it has no gAMA chunk and if png_set_gamma() has not been called
+ * to override the PNG gamma information.
+ *
+ * When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
+ * opaque pixels however pixels with lower alpha values are not encoded,
+ * regardless of the output gamma setting.
+ *
+ * When the standard Porter Duff handling is requested with mode 1 the output
+ * encoding is set to be linear and the output_gamma value is only relevant
+ * as a default for input data that has no gamma information. The linear output
+ * encoding will be overridden if png_set_gamma() is called - the results may be
+ * highly unexpected!
+ *
+ * The following numbers are derived from the sRGB standard and the research
+ * behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
+ * 0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
+ * correction required to take account of any differences in the color
+ * environment of the original scene and the intended display environment; the
+ * value expresses how to *decode* the image for display, not how the original
+ * data was *encoded*.
+ *
+ * sRGB provides a peg for the PNG standard by defining a viewing environment.
+ * sRGB itself, and earlier TV standards, actually use a more complex transform
+ * (a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
+ * limited to simple power laws.) By saying that an image for direct display on
+ * an sRGB conformant system should be stored with a gAMA chunk value of 45455
+ * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+ * makes it possible to derive values for other display systems and
+ * environments.
+ *
+ * The Mac value is deduced from the sRGB based on an assumption that the actual
+ * extra viewing correction used in early Mac display systems was implemented as
+ * a power 1.45 lookup table.
+ *
+ * Any system where a programmable lookup table is used or where the behavior of
+ * the final display device characteristics can be changed requires system
+ * specific code to obtain the current characteristic. However this can be
+ * difficult and most PNG gamma correction only requires an approximate value.
+ *
+ * By default, if png_set_alpha_mode() is not called, libpng assumes that all
+ * values are unencoded, linear, values and that the output device also has a
+ * linear characteristic. This is only very rarely correct - it is invariably
+ * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+ * default if you don't know what the right answer is!
+ *
+ * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+ * 10.6) which used a correction table to implement a somewhat lower gamma on an
+ * otherwise sRGB system.
+ *
+ * Both these values are reserved (not simple gamma values) in order to allow
+ * more precise correction internally in the future.
+ *
+ * NOTE: the following values can be passed to either the fixed or floating
+ * point APIs, but the floating point API will also accept floating point
+ * values.

+ * This is the default libpng handling of the alpha channel - it is not
+ * pre-multiplied into the color components. In addition the call states
+ * that the output is for a sRGB system and causes all PNG files without gAMA
+ * chunks to be assumed to be encoded using sRGB.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ * In this case the output is assumed to be something like an sRGB conformant
+ * display preceeded by a power-law lookup table of power 1.45. This is how
+ * early Mac systems behaved.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
+ * This is the classic Jim Blinn approach and will work in academic
+ * environments where everything is done by the book. It has the shortcoming
+ * of assuming that input PNG data with no gamma information is linear - this
+ * is unlikely to be correct unless the PNG files where generated locally.
+ * Most of the time the output precision will be so low as to show
+ * significant banding in dark areas of the image.
+ *
+ * png_set_expand_16(pp);
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+ * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
+ * are assumed to have the sRGB encoding if not marked with a gamma value and
+ * the output is always 16 bits per component. This permits accurate scaling
+ * and processing of the data. If you know that your input PNG files were
+ * generated locally you might need to replace PNG_DEFAULT_sRGB with the
+ * correct value for your system.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+ * If you just need to composite the PNG image onto an existing background
+ * and if you control the code that does this you can use the optimization
+ * setting. In this case you just copy completely opaque pixels to the
+ * output. For pixels that are not completely transparent (you just skip
+ * those) you do the composition math using png_composite or png_composite_16
+ * below then encode the resultant 8-bit or 16-bit values to match the output
+ * encoding.
+ *
+ * Other cases
+ * If neither the PNG nor the standard linear encoding work for you because
+ * of the software or hardware you use then you have a big problem. The PNG
+ * case will probably result in halos around the image. The linear encoding
+ * will probably result in a washed out, too bright, image (it's actually too
+ * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+ * substantially reduce the halos. Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ * This option will also reduce the halos, but there will be slight dark
+ * halos round the opaque parts of the image where the background is light.
+ * In the OPTIMIZED mode the halos will be light halos where the background
+ * is dark. Take your pick - the halos are unavoidable unless you can get
+ * your hardware/software fixed! (The OPTIMIZED approach is slightly
+ * faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ * If you have PNG files with no gamma information png_set_alpha_mode allows
+ * you to provide a default gamma, but it also sets the ouput gamma to the
+ * matching value. If you know your PNG files have a gamma that doesn't
+ * match the output you can take advantage of the fact that
+ * png_set_alpha_mode always sets the output gamma but only sets the PNG
+ * default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ * The first call sets both the default and the output gamma values, the
+ * second call overrides the output gamma without changing the default. This
+ * is easier than achieving the same effect with png_set_gamma. You must use
+ * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ * fire if more than one call to png_set_alpha_mode and png_set_background is
+ * made in the same read operation, however multiple calls with PNG_ALPHA_PNG

+ *
+ * Poynton's current link (as of January 2003 through July 2011):
+ * <http://www.poynton.com/notes/colour_and_gamma/>
+ * has changed the numbers slightly:
*
- * Y = 0.21268 * R + 0.7151 * G + 0.07217 * B
+ * Y = 0.2126*R + 0.7152*G + 0.0722*B
*
* which can be expressed with integers as
*
- * Y = (6969 * R + 23434 * G + 2365 * B)/32768
+ * Y = (6966 * R + 23436 * G + 2366 * B)/32768
+ *
+ * Historically, however, libpng uses numbers derived from the ITU-R Rec 709
+ * end point chromaticities and the D65 white point. Depending on the
+ * precision used for the D65 white point this produces a variety of different
+ * numbers, however if the four decimal place value used in ITU-R Rec 709 is
+ * used (0.3127,0.3290) the Y calculation would be:
+ *
+ * Y = (6968 * R + 23435 * G + 2366 * B)/32768
+ *
+ * While this is correct the rounding results in an overflow for white, because
+ * the sum of the rounded coefficients is 32769, not 32768. Consequently
+ * libpng uses, instead, the closest non-overflowing approximation:
*
- * The calculation is to be done in a linear colorspace.
+ * Y = (6968 * R + 23434 * G + 2366 * B)/32768
*
- * Other integer coefficents can be used via png_set_rgb_to_gray().
+ * Starting with libpng-1.5.5, if the image being converted has a cHRM chunk
+ * (including an sRGB chunk) then the chromaticities are used to calculate the
+ * coefficients. See the chunk handling in pngrutil.c for more information.
+ *
+ * In all cases the calculation is to be done in a linear colorspace. If no
+ * gamma information is available to correct the encoding of the original RGB
+ * values this results in an implicit assumption that the original PNG RGB
+ * values were linear.
+ *
+ * Other integer coefficents can be used via png_set_rgb_to_gray(). Because
+ * the API takes just red and green coefficients the blue coefficient is
+ * calculated to make the sum 32768. This will result in different rounding
+ * to that used above.

+For 32-bit platforms, do not try to accelerate multiple neighboring

+
+The main target for this optimization is ARM, but 32-bit x86 gets

+Also, reactivate the 2 MB test for 64-bit platforms; there's no good
+reason why it shouldn't be.

+Fix public issue r57: Fix most warnings with -Wall, mostly signed/unsigned
+warnings. There are still some in the unit test, but the main .cc file should
+be clean. We haven't enabled -Wall for the default build, since the unit test
+is still not clean.
+
+This also fixes a real bug in the open-source implementation of
+ReadFileToStringOrDie(); it would not detect errors correctly.
+
+I had to go through some pains to avoid performance loss as the types
+were changed; I think there might still be some with 32-bit if and only if LFS
+is enabled (ie., size_t is 64-bit), but for regular 32-bit and 64-bit I can't
+see any losses, and I've diffed the generated GCC assembler between the old and
+new code without seeing any significant choices. If anything, it's ever so
+slightly faster.
+
+This may or may not enable compression of very large blocks (>2^32 bytes)
+when size_t is 64-bit, but I haven't checked, and it is still not a supported
+case.

+Speed up decompression by moving the refill check to the end of the loop.
+
+This seems to work because in most of the branches, the compiler can evaluate
+“ip_limit_ - ip” in a more efficient way than reloading ip_limit_ from memory
+(either by already having the entire expression in a register, or reconstructing
+it from “avail”, or something else). Memory loads, even from L1, are seemingly
+costly in the big picture at the current decompression speeds.

+Speed up decompression by making the fast path for literals faster.
+
+We do the fast-path step as soon as possible; in fact, as soon as we know the
+literal length. Since we usually hit the fast path, we can then skip the checks
+for long literals and available input space (beyond what the fast path check
+already does).
+
+Note that this changes the decompression Writer API; however, it does not
+change the ABI, since writers are always templatized and as such never
+cross compilation units. The new API is slightly more general, in that it
+doesn't hard-code the value 16. Note that we also take care to check
+for len <= 16 first, since the other two checks almost always succeed
+(so we don't want to waste time checking for them until we have to).
+
+The improvements are most marked on Nehalem, but are generally positive
+on other platforms as well. All microbenchmarks are 64-bit, opt.

+Snappy v1.0.5, February 24th 2012:
+
+ * More speed improvements. Exactly how big will depend on
+ the architecture:
+
+ - 3–10% faster decompression for the base case (x86-64).
+
+ - ARMv7 and higher can now use unaligned accesses,
+ and will see about 30% faster decompression and
+ 20–40% faster compression.
+
+ - 32-bit platforms (ARM and 32-bit x86) will see 2–5%
+ faster compression.
+
+ These are all cumulative (e.g., ARM gets all three speedups).
+
+ * Fixed an issue where the unit test would crash on system
+ with less than 256 MB address space available,
+ e.g. some embedded platforms.
+
+ * Added a framing format description, for use over e.g. HTTP,
+ or for a command-line compressor. We do not have any
+ implementations of this at the current point, but there seems
+ to be enough of a general interest in the topic.
+ Also make the format description slightly clearer.
+
+ * Remove some compile-time warnings in -Wall
+ (mostly signed/unsigned comparisons), for easier embedding
+ into projects that use -Wall -Werror.

There are many ways to call Snappy, but the simplest possible is
- snappy::Compress(input, &output);
+ snappy::Compress(input.data(), input.size(), &output);
and similarly
- snappy::Uncompress(input, &output);
+ snappy::Uncompress(input.data(), input.size(), &output);
where "input" and "output" are both instances of std::string.

This is not a formal specification, but should suffice to explain most
stored as a little-endian varint. Varints consist of a series of bytes,
where the lower 7 bits are data and the upper bit is set iff there are
more bytes to be read. In other words, an uncompressed length of 64 would
-be stored as 0x40, and an uncompressed length of 2097151 (0x1FFFFF)
-would be stored as 0xFF 0xFF 0x7F.
+be stored as 0x40, and an uncompressed length of 2097150 (0x1FFFFE)
+would be stored as 0xFE 0xFF 0x7F.
2. The compressed stream itself
--- /dev/null
+Snappy framing format description
+Last revised: 2011-12-15
+
+This format decribes a framing format for Snappy, allowing compressing to
+files or streams that can then more easily be decompressed without having
+to hold the entire stream in memory. It also provides data checksums to
+help verify integrity. It does not provide metadata checksums, so it does
+not protect against e.g. all forms of truncations.
+
+Implementation of the framing format is optional for Snappy compressors and
+decompressor; it is not part of the Snappy core specification.
+
+
+1. General structure
+
+The file consists solely of chunks, lying back-to-back with no padding
+in between. Each chunk consists first a single byte of chunk identifier,
+then a two-byte little-endian length of the chunk in bytes (from 0 to 65535,
+inclusive), and then the data if any. The three bytes of chunk header is not
+counted in the data length.
+
+The different chunk types are listed below. The first chunk must always
+be the stream identifier chunk (see section 4.1, below). The stream
+ends when the file ends -- there is no explicit end-of-file marker.
+
+
+2. File type identification
+
+The following identifiers for this format are recommended where appropriate.
+However, note that none have been registered officially, so this is only to
+be taken as a guideline. We use "Snappy framed" to distinguish between this
+format and raw Snappy data.
+
+ File extension: .sz
+ MIME type: application/x-snappy-framed
+ HTTP Content-Encoding: x-snappy-framed
+
+
+3. Checksum format
+
+Some chunks have data protected by a checksum (the ones that do will say so
+explicitly). The checksums are always masked CRC-32Cs.
+
+A description of CRC-32C can be found in RFC 3720, section 12.1, with
+examples in section B.4.
+
+Checksums are not stored directly, but masked, as checksumming data and
+then its own checksum can be problematic. The masking is the same as used
+in Apache Hadoop: Rotate the checksum by 15 bits, then add the constant
+0xa282ead8 (using wraparound as normal for unsigned integers). This is
+equivalent to the following C code:
+
+ uint32_t mask_checksum(uint32_t x) {
+ return ((x >> 15) | (x << 17)) + 0xa282ead8;
+ }
+
+Note that the masking is reversible.
+
+The checksum is always stored as a four bytes long integer, in little-endian.
+
+
+4. Chunk types
+
+The currently supported chunk types are described below. The list may
+be extended in the future.
+
+
+4.1. Stream identifier (chunk type 0xff)
+
+The stream identifier is always the first element in the stream.
+It is exactly six bytes long and contains "sNaPpY" in ASCII. This means that
+a valid Snappy framed stream always starts with the bytes
+
+ 0xff 0x06 0x00 0x73 0x4e 0x61 0x50 0x70 0x59
+
+The stream identifier chunk can come multiple times in the stream besides
+the first; if such a chunk shows up, it should simply be ignored, assuming
+it has the right length and contents. This allows for easy concatenation of
+compressed files without the need for re-framing.
+
+
+4.2. Compressed data (chunk type 0x00)
+
+Compressed data chunks contain a normal Snappy compressed bitstream;
+see the compressed format specification. The compressed data is preceded by
+the CRC-32C (see section 3) of the _uncompressed_ data.
+
+Note that the data portion of the chunk, i.e., the compressed contents,
+can be at most 65531 bytes (2^16 - 1, minus the checksum).
+However, we place an additional restriction that the uncompressed data
+in a chunk must be no longer than 32768 bytes. This allows consumers to
+easily use small fixed-size buffers.
+
+
+4.3. Uncompressed data (chunk type 0x01)
+
+Uncompressed data chunks allow a compressor to send uncompressed,
+raw data; this is useful if, for instance, uncompressible or
+near-incompressible data is detected, and faster decompression is desired.
+
+As in the compressed chunks, the data is preceded by its own masked
+CRC-32C (see section 3).
+
+An uncompressed data chunk, like compressed data chunks, should contain
+no more than 32768 data bytes, so the maximum legal chunk length with the
+checksum is 32772.
+
+
+4.4. Reserved unskippable chunks (chunk types 0x02-0x7f)
+
+These are reserved for future expansion. A decoder that sees such a chunk
+should immediately return an error, as it must assume it cannot decode the
+stream correctly.
+
+Future versions of this specification may define meanings for these chunks.
+
+
+4.5. Reserved skippable chunks (chunk types 0x80-0xfe)
+
+These are also reserved for future expansion, but unlike the chunks
+described in 4.4, a decoder seeing these must skip them and continue
+decoding.
+
+Future versions of this specification may define meanings for these chunks.

-of the library is given in the file example.c which also tests that the library
-is working correctly. Another example is given in the file minigzip.c. The
-compression library itself is composed of all source files except example.c and
