Libpng 1.6.28 - January 5, 2017
|
|
||||||
|
|
||||||
This is a public release of libpng, intended for use in production codes.
|
|
||||||
|
|
||||||
Files available for download:
|
|
||||||
|
|
||||||
Source files with LF line endings (for Unix/Linux) and with a
|
|
||||||
"configure" script
|
|
||||||
|
|
||||||
libpng-1.6.28.tar.xz (LZMA-compressed, recommended)
|
|
||||||
libpng-1.6.28.tar.gz
|
|
||||||
|
|
||||||
Source files with CRLF line endings (for Windows), without the
|
|
||||||
"configure" script
|
|
||||||
|
|
||||||
lpng1628.7z (LZMA-compressed, recommended)
|
|
||||||
lpng1628.zip

|
|
||||||
libpng-1.6.28-*.asc (armored detached GPG signatures)
|
|
||||||
|
|
||||||
Changes since the last public release (1.6.27):
|
|
||||||
Fixed arm/aarch64 detection in CMakeLists.txt (Gianfranco Costamagna).
|
|
||||||
Added option to Cmake build allowing a custom location of zlib to be
|
|
||||||
specified in a scenario where libpng is being built as a subproject
|
|
||||||
alongside zlib by another project (Sam Serrels).
|
|
||||||
Changed png_ptr->options from a png_byte to png_uint_32, to accomodate
|
|
||||||
up to 16 options.

|
||||||
|
|
||||||
I. Simple installation
|
|
||||||
|
|
||||||
On Unix/Linux and similar systems, you can simply type
|
|
||||||
|
|
||||||
./configure [--prefix=/path]
|
|
||||||
make check
|
|
||||||
make install
|
|
||||||
|
|
||||||
and ignore the rest of this document. "/path" is the path to the directory
|
|
||||||
where you want to install the libpng "lib", "include", and "bin"
|
|
||||||
subdirectories.
|
|
||||||
|
|
||||||
If you downloaded a GIT clone, you will need to run ./autogen.sh before
|
|
||||||
running ./configure, to create "configure" and "Makefile.in" which are
|
|
||||||
not included in the GIT repository.
|
|
||||||
|
|
||||||
Note that "configure" is only included in the "*.tar" distributions and not
|
|
||||||
in the "*.zip" or "*.7z" distributions. If you downloaded one of those
|
|
||||||
distributions, see "Building with project files" or "Building with makefiles",
|
|
||||||
below.
|
|
||||||
|
|
||||||
II. Rebuilding the configure scripts
|
|
||||||
|
|
||||||
If configure does not work on your system, or if you have a need to
|
|
||||||
change configure.ac or Makefile.am, and you have a reasonably
|
|
||||||
up-to-date set of tools, running ./autogen.sh in a git clone before
|
|
||||||
running ./configure may fix the problem. To be really sure that you
|
|
||||||
aren't using any of the included pre-built scripts, especially if you
|
|
||||||
are building from a tar distribution instead of a git distribution,
|
|
||||||
do this:
|
|
||||||
|
|
||||||
./configure --enable-maintainer-mode
|
|
||||||
make maintainer-clean
|
|
||||||
./autogen.sh --maintainer --clean
|
|
||||||
./autogen.sh --maintainer
|
|
||||||
./configure [--prefix=/path] [other options]
|
|
||||||
make
|
|
||||||
make install
|
|
||||||
make check
|
|
||||||
|
|
||||||
III. Using scripts/makefile*
|
|
||||||
|
|
||||||
Instead, you can use one of the custom-built makefiles in the
|
|
||||||
"scripts" directory
|
|
||||||
|
|
||||||
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
|
|
||||||
cp scripts/makefile.system makefile
|
|
||||||
make test
|
|
||||||
make install
|
|
||||||
|
|
||||||
The files that are presently available in the scripts directory
|
|
||||||
are listed and described in scripts/README.txt.
|
|
||||||
|
|
||||||
Or you can use one of the "projects" in the "projects" directory.
|
|
||||||
|
|
||||||
Before installing libpng, you must first install zlib, if it
|
|
||||||
is not already on your system. zlib can usually be found
|
|
||||||
wherever you got libpng; otherwise go to http://zlib.net. You can place
|
|
||||||
zlib in the same directory as libpng or in another directory.
|
|
||||||
|
|
||||||
If your system already has a preinstalled zlib you will still need
|
|
||||||
to have access to the zlib.h and zconf.h include files that
|
|
||||||
correspond to the version of zlib that's installed.
|
|
||||||
|
|
||||||
If you wish to test with a particular zlib that is not first in the
|
|
||||||
standard library search path, put ZLIBLIB, ZLIBINC, CPPFLAGS, LDFLAGS,
|
|
||||||
and LD_LIBRARY_PATH in your environment before running "make test"
|
|
||||||
or "make distcheck":
|
|
||||||
|
|
||||||
ZLIBLIB=/path/to/lib export ZLIBLIB
|
|
||||||
ZLIBINC=/path/to/include export ZLIBINC
|
|
||||||
CPPFLAGS="-I$ZLIBINC" export CPPFLAGS
|
|
||||||
LDFLAGS="-L$ZLIBLIB" export LDFLAGS
|
|
||||||
LD_LIBRARY_PATH="$ZLIBLIB:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH
|
|
||||||
|
|
||||||
If you are using one of the makefile scripts, put ZLIBLIB and ZLIBINC
|
|
||||||
in your environment and type
|
|
||||||
|
|
||||||
make ZLIBLIB=$ZLIBLIB ZLIBINC=$ZLIBINC test
|
|
||||||
|
|
||||||
IV. Using cmake
|
|
||||||
|
|
||||||
If you want to use "cmake" (see www.cmake.org), type
|
|
||||||
|
|
||||||
cmake . -DCMAKE_INSTALL_PREFIX=/path
|
|
||||||
make
|
|
||||||
make install
|
|
||||||
|
|
||||||
As when using the simple configure method described above, "/path" points to
|
|
||||||
the installation directory where you want to put the libpng "lib", "include",
|
|
||||||
and "bin" subdirectories.
|
|
||||||
|
|
||||||
V. Directory structure
|
|
||||||
|
|
||||||
You can rename the directories that you downloaded (they
|
|
||||||
might be called "libpng-x.y.z" or "libpngNN" and "zlib-1.2.8"
|
|
||||||
or "zlib128") so that you have directories called "zlib" and "libpng".
|
|
||||||
|
|
||||||
Your directory structure should look like this:
|
|
||||||
|
|
||||||
.. (the parent directory)
|
|
||||||
libpng (this directory)
|
|
||||||
INSTALL (this file)
|
|
||||||
README
|
|
||||||
*.h, *.c => libpng source files
|
|
||||||
CMakeLists.txt => "cmake" script
|
|
||||||
configuration files:
|
|
||||||
configure.ac, configure, Makefile.am, Makefile.in,
|
|
||||||
autogen.sh, config.guess, ltmain.sh, missing, libpng.pc.in,
|
|
||||||
libpng-config.in, aclocal.m4, config.h.in, config.sub,
|
|
||||||
depcomp, install-sh, mkinstalldirs, test-pngtest.sh
|
|
||||||
contrib
|
|
||||||
arm-neon, conftest, examples, gregbook, libtests, pngminim,
|
|
||||||
pngminus, pngsuite, tools, visupng
|
|
||||||
projects
|
|
||||||
cbuilder5, owatcom, visualc71, vstudio, xcode
|
|
||||||
scripts
|
|
||||||
makefile.*
|
|
||||||
*.def (module definition files)
|
|
||||||
etc.
|
|
||||||
pngtest.png
|
|
||||||
etc.
|
|
||||||
zlib
|
|
||||||
README, *.h, *.c contrib, etc.
|
|
||||||
|
|
||||||
If the line endings in the files look funny, you may wish to get the other
|
|
||||||
distribution of libpng. It is available in both tar.gz (UNIX style line
|
|
||||||
endings) and zip (DOS style line endings) formats.
|
|
||||||
|
|
||||||
VI. Building with project files
|
|
||||||
|
|
||||||
If you are building libpng with MSVC, you can enter the
|
|
||||||
libpng projects\visualc71 or vstudio directory and follow the instructions
|
|
||||||
in README.txt.
|
|
||||||
|
|
||||||
Otherwise enter the zlib directory and follow the instructions in zlib/README,
|
|
||||||
then come back here and run "configure" or choose the appropriate
|
|
||||||
makefile.sys in the scripts directory.
|
|
||||||
|
|
||||||
VII. Building with makefiles
|
|
||||||
|
|
||||||
Copy the file (or files) that you need from the
|
|
||||||
scripts directory into this directory, for example
|
|
||||||
|
|
||||||
MSDOS example:
|
|
||||||
|
|
||||||
copy scripts\makefile.msc makefile
|
|
||||||
copy scripts\pnglibconf.h.prebuilt pnglibconf.h
|
|
||||||
|
|
||||||
UNIX example:
|
|
||||||
|
|
||||||
cp scripts/makefile.std makefile
|
|
||||||
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
|
|
||||||
|
|
||||||
Read the makefile to see if you need to change any source or
|
|
||||||
target directories to match your preferences.
|
|
||||||
|
|
||||||
Then read pnglibconf.dfa to see if you want to make any configuration
|
|
||||||
changes.
|
|
||||||
|
|
||||||
Then just run "make" which will create the libpng library in
|
|
||||||
this directory and "make test" which will run a quick test that reads
|
|
||||||
the "pngtest.png" file and writes a "pngout.png" file that should be
|
|
||||||
identical to it. Look for "9782 zero samples" in the output of the
|
|
||||||
test. For more confidence, you can run another test by typing
|
|
||||||
"pngtest pngnow.png" and looking for "289 zero samples" in the output.
|
|
||||||
Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare
|
|
||||||
your output with the result shown in contrib/pngsuite/README.
|
|
||||||
|
|
||||||
Most of the makefiles will allow you to run "make install" to
|
|
||||||
put the library in its final resting place (if you want to
|
|
||||||
do that, run "make install" in the zlib directory first if necessary).
|
|
||||||
Some also allow you to run "make test-installed" after you have
|
|
||||||
run "make install".
|
|
||||||
|
|
||||||
VIII. Configuring libpng for 16-bit platforms
|
|
||||||
|
|
||||||
You will want to look into zconf.h to tell zlib (and thus libpng) that
|
|
||||||
it cannot allocate more than 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.
|
|
||||||
|
|
||||||
IX. 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.
|
|
||||||
|
|
||||||
X. 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 *".
|
|
||||||
|
|
||||||
XI. Prepending a prefix to exported symbols
|
|
||||||
|
|
||||||
Starting with libpng-1.6.0, you can configure libpng (when using the
|
|
||||||
"configure" script) to prefix all exported symbols by means of the
|
|
||||||
configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any
|
|
||||||
string beginning with a letter and containing only uppercase
|
|
||||||
and lowercase letters, digits, and the underscore (i.e., a C language
|
|
||||||
identifier). This creates a set of macros in pnglibconf.h, so this is
|
|
||||||
transparent to applications; their function calls get transformed by
|
|
||||||
the macros to use the modified names.
|
|
||||||
|
|
||||||
XII. 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 and, as of libpng-1.5.0, pnglibconf.h.
|
|
||||||
As of libpng-1.5.0, pngpriv.h also includes three other private header
|
|
||||||
files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material
|
|
||||||
that previously appeared in the public headers.
|
|
||||||
|
|
||||||
XIII. 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_".
|
|
||||||
|
|
||||||
In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead.
|
|
||||||
|
|
||||||
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.
|
|
||||||
|
|
||||||
XIV. Changes to the build and configuration of libpng in libpng-1.5.x
|
|
||||||
|
|
||||||
Details of internal changes to the library code can be found in the CHANGES
|
|
||||||
file and in the GIT repository logs. These will be of no concern to the vast
|
|
||||||
majority of library users or builders; however, the few who configure libpng
|
|
||||||
to a non-default feature set may need to change how this is done.
|
|
||||||
|
|
||||||
There should be no need for library builders to alter build scripts if
|
|
||||||
these use the distributed build support - configure or the makefiles -
|
|
||||||
however, users of the makefiles may care to update their build scripts
|
|
||||||
to build pnglibconf.h where the corresponding makefile does not do so.
|
|
||||||
|
|
||||||
Building libpng with a non-default configuration has changed completely.
|
|
||||||
The old method using pngusr.h should still work correctly even though the
|
|
||||||
way pngusr.h is used in the build has been changed; however, library
|
|
||||||
builders will probably want to examine the changes to take advantage of
|
|
||||||
new capabilities and to simplify their build system.
|
|
||||||
|
|
||||||
A. Specific changes to library configuration capabilities
|
|
||||||
|
|
||||||
The exact mechanism used to control attributes of API functions has
|
|
||||||
changed. A single set of operating system independent macro definitions
|
|
||||||
is used and operating system specific directives are defined in
|
|
||||||
pnglibconf.h
|
|
||||||
|
|
||||||
As part of this the mechanism used to choose procedure call standards on
|
|
||||||
those systems that allow a choice has been changed. At present this only
|
|
||||||
affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems
|
|
||||||
running on Intel processors. As before, PNGAPI is defined where required
|
|
||||||
to control the exported API functions; however, two new macros, PNGCBAPI
|
|
||||||
and PNGCAPI, are used instead for callback functions (PNGCBAPI) and
|
|
||||||
(PNGCAPI) for functions that must match a C library prototype (currently
|
|
||||||
only png_longjmp_ptr, which must match the C longjmp function.) The new
|
|
||||||
approach is documented in pngconf.h
|
|
||||||
|
|
||||||
Despite these changes, libpng 1.5.0 only supports the native C function
|
|
||||||
calling standard on those platforms tested so far ("__cdecl" on Microsoft
|
|
||||||
Windows). This is because the support requirements for alternative
|
|
||||||
calling conventions seem to no longer exist. Developers who find it
|
|
||||||
necessary to set PNG_API_RULE to 1 should advise the mailing list
|
|
||||||
(png-mng-implement) of this and library builders who use Openwatcom and
|
|
||||||
therefore set PNG_API_RULE to 2 should also contact the mailing list.
|
|
||||||
|
|
||||||
B. Changes to the configuration mechanism
|
|
||||||
|
|
||||||
Prior to libpng-1.5.0 library builders who needed to configure libpng
|
|
||||||
had either to modify the exported pngconf.h header file to add system
|
|
||||||
specific configuration or had to write feature selection macros into
|
|
||||||
pngusr.h and cause this to be included into pngconf.h by defining
|
|
||||||
PNG_USER_CONFIG. The latter mechanism had the disadvantage that an
|
|
||||||
application built without PNG_USER_CONFIG defined would see the
|
|
||||||
unmodified, default, libpng API and thus would probably fail to link.
|
|
||||||
|
|
||||||
These mechanisms still work in the configure build and in any makefile
|
|
||||||
build that builds pnglibconf.h, although the feature selection macros
|
|
||||||
have changed somewhat as described above. In 1.5.0, however, pngusr.h is
|
|
||||||
processed only once, at the time the exported header file pnglibconf.h is
|
|
||||||
built. pngconf.h no longer includes pngusr.h; therefore, pngusr.h is ignored
|
|
||||||
after the build of pnglibconf.h and it is never included in an application
|
|
||||||
build.
|
|
||||||
|
|
||||||
The formerly used alternative of adding a list of feature macros to the
|
|
||||||
CPPFLAGS setting in the build also still works; however, the macros will be
|
|
||||||
copied to pnglibconf.h and this may produce macro redefinition warnings
|
|
||||||
when the individual C files are compiled.
|
|
||||||
|
|
||||||
All configuration now only works if pnglibconf.h is built from
|
|
||||||
scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
|
|
||||||
(the original author of awk) maintains C source code of that awk and this
|
|
||||||
and all known later implementations (often called by subtly different
|
|
||||||
names - nawk and gawk for example) are adequate to build pnglibconf.h.
|
|
||||||
The Sun Microsystems (now Oracle) program 'awk' is an earlier version
|
|
||||||
and does not work; this may also apply to other systems that have a
|
|
||||||
functioning awk called 'nawk'.
|
|
||||||
|
|
||||||
Configuration options are now documented in scripts/pnglibconf.dfa. This
|
|
||||||
file also includes dependency information that ensures a configuration is
|
|
||||||
consistent; that is, if a feature is switched off, dependent features are
|
|
||||||
also switched off. As a recommended alternative to using feature macros in
|
|
||||||
pngusr.h a system builder may also define equivalent options in pngusr.dfa
|
|
||||||
(or, indeed, any file) and add that to the configuration by setting
|
|
||||||
DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate
|
|
||||||
how to do this, and also illustrate a case where pngusr.h is still required.
|
|
||||||
|
|
||||||
After you have built libpng, the definitions that were recorded in
|
|
||||||
pnglibconf.h are available to your application (pnglibconf.h is included
|
|
||||||
in png.h and gets installed alongside png.h and pngconf.h in your
|
|
||||||
$PREFIX/include directory). Do not edit pnglibconf.h after you have built
|
|
||||||
libpng, because than the settings would not accurately reflect the settings
|
|
||||||
that were used to build libpng.
|
|
||||||
|
|
||||||
XV. Setjmp/longjmp issues
|
|
||||||
|
|
||||||
Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp()
|
|
||||||
is known to be not thread-safe on some platforms and we don't know of
|
|
||||||
any platform where it is guaranteed to be thread-safe. Therefore, if
|
|
||||||
your application is going to be using multiple threads, you should
|
|
||||||
configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with
|
|
||||||
-DPNG_NO_SETJMP on your compile line, or with
|
|
||||||
|
|
||||||
#undef PNG_SETJMP_SUPPORTED
|
|
||||||
|
|
||||||
in your pnglibconf.h or pngusr.h.
|
|
||||||
|
|
||||||
Starting with libpng-1.6.0, the library included a "simplified API".
|
|
||||||
This requires setjmp/longjmp, so you must either build the library
|
|
||||||
with PNG_SETJMP_SUPPORTED defined, or with PNG_SIMPLIFIED_READ_SUPPORTED
|
|
||||||
and PNG_SIMPLIFIED_WRITE_SUPPORTED undefined.
|
|
||||||
|
|
||||||
XVI. Common linking failures
|
|
||||||
|
|
||||||
If your application fails to find libpng or zlib entries while linking:
|
|
||||||
|
|
||||||
Be sure "-lz" appears after "-lpng" on your linking command.
|
|
||||||
|
|
||||||
Be sure you have built libpng, zlib, and your application for the
|
|
||||||
same platform (e.g., 32-bit or 64-bit).
|
|
||||||
|
|
||||||
If you are using the vstudio project, observe the WARNING in
|
|
||||||
project/vstudio/README.txt.

README for libpng version 1.6.28 - January 5, 2017 (shared library 16.0)
|
|
||||||
See the note about version numbers near the top of png.h
|
|
||||||
|
|
||||||
See INSTALL for instructions on how to install libpng.
|
|
||||||
|
|
||||||
Libpng comes in several distribution formats. Get libpng-*.tar.gz or
|
|
||||||
libpng-*.tar.xz or if you want UNIX-style line endings in the text files,
|
|
||||||
or lpng*.7z or lpng*.zip if you want DOS-style line endings.
|
|
||||||
|
|
||||||
Version 0.89 was the first official release of libpng. Don't let the
|
|
||||||
fact that it's the first release fool you. The libpng library has been in
|
|
||||||
extensive use and testing since mid-1995. By late 1997 it had
|
|
||||||
finally gotten to the stage where there hadn't been significant
|
|
||||||
changes to the API in some time, and people have a bad feeling about
|
|
||||||
libraries with versions < 1.0. Version 1.0.0 was released in
|
|
||||||
March 1998.
|
|
||||||
|
|
||||||
****
|
|
||||||
Note that some of the changes to the png_info structure render this
|
|
||||||
version of the library binary incompatible with libpng-0.89 or
|
|
||||||
earlier versions if you are using a shared library. The type of the
|
|
||||||
"filler" parameter for png_set_filler() has changed from png_byte to
|
|
||||||
png_uint_32, which will affect shared-library applications that use
|
|
||||||
this function.
|
|
||||||
|
|
||||||
To avoid problems with changes to the internals of png info_struct,
|
|
||||||
new APIs have been made available in 0.95 to avoid direct application
|
|
||||||
access to info_ptr. These functions are the png_set_<chunk> and
|
|
||||||
png_get_<chunk> functions. These functions should be used when
|
|
||||||
accessing/storing the info_struct data, rather than manipulating it
|
|
||||||
directly, to avoid such problems in the future.
|
|
||||||
|
|
||||||
It is important to note that the APIs did not make current programs
|
|
||||||
that access the info struct directly incompatible with the new
|
|
||||||
library, through libpng-1.2.x. In libpng-1.4.x, which was meant to
|
|
||||||
be a transitional release, members of the png_struct and the
|
|
||||||
info_struct can still be accessed, but the compiler will issue a
|
|
||||||
warning about deprecated usage. Since libpng-1.5.0, direct access
|
|
||||||
to these structs is not allowed, and the definitions of the structs
|
|
||||||
reside in private pngstruct.h and pnginfo.h header files that are not
|
|
||||||
accessible to applications. It is strongly suggested that new
|
|
||||||
programs use the new APIs (as shown in example.c and pngtest.c), and
|
|
||||||
older programs be converted to the new format, to facilitate upgrades
|
|
||||||
in the future.
|
|
||||||
****
|
|
||||||
|
|
||||||
Additions since 0.90 include the ability to compile libpng as a
|
|
||||||
Windows DLL, and new APIs for accessing data in the info struct.
|
|
||||||
Experimental functions include the ability to set weighting and cost
|
|
||||||
factors for row filter selection, direct reads of integers from buffers
|
|
||||||
on big-endian processors that support misaligned data access, faster
|
|
||||||
methods of doing alpha composition, and more accurate 16->8 bit color
|
|
||||||
conversion.
|
|
||||||
|
|
||||||
The additions since 0.89 include the ability to read from a PNG stream
|
|
||||||
which has had some (or all) of the signature bytes read by the calling
|
|
||||||
application. This also allows the reading of embedded PNG streams that
|
|
||||||
do not have the PNG file signature. As well, it is now possible to set
|
|
||||||
the library action on the detection of chunk CRC errors. It is possible
|
|
||||||
to set different actions based on whether the CRC error occurred in a
|
|
||||||
critical or an ancillary chunk.
|
|
||||||
|
|
||||||
The changes made to the library, and bugs fixed are based on discussions
|
|
||||||
on the PNG-implement mailing list and not on material submitted
|
|
||||||
privately to Guy, Andreas, or Glenn. They will forward any good
|
|
||||||
suggestions to the list.
|
|
||||||
|
|
||||||
For a detailed description on using libpng, read libpng-manual.txt. For
|
|
||||||
examples of libpng in a program, see example.c and pngtest.c. For usage
|
|
||||||
information and restrictions (what little they are) on libpng, see
|
|
||||||
png.h. For a description on using zlib (the compression library used by
|
|
||||||
libpng) and zlib's restrictions, see zlib.h
|
|
||||||
|
|
||||||
I have included a general makefile, as well as several machine and
|
|
||||||
compiler specific ones, but you may have to modify one for your own needs.
|
|
||||||
|
|
||||||
You should use zlib 1.0.4 or later to run this, but it MAY work with
|
|
||||||
versions as old as zlib 0.95. Even so, there are bugs in older zlib
|
|
||||||
versions which can cause the output of invalid compression streams for
|
|
||||||
some images. You will definitely need zlib 1.0.4 or later if you are
|
|
||||||
taking advantage of the MS-DOS "far" structure allocation for the small
|
|
||||||
and medium memory models. You should also note that zlib is a
|
|
||||||
compression library that is useful for more things than just PNG files.
|
|
||||||
You can use zlib as a drop-in replacement for fread() and fwrite() if
|
|
||||||
you are so inclined.
|
|
||||||
|
|
||||||
zlib should be available at the same place that libpng is, or at zlib.net.
|
|
||||||
|
|
||||||
You may also want a copy of the PNG specification. It is available
|
|
||||||
as an RFC, a W3C Recommendation, and an ISO/IEC Standard. You can find
|
|
||||||
these at http://www.libpng.org/pub/png/documents/
|
|
||||||
|
|
||||||
This code is currently being archived at libpng.sf.net in the
|
|
||||||
[DOWNLOAD] area, and at ftp://ftp.simplesystems.org. If you can't find it
|
|
||||||
in any of those places, e-mail me, and I'll help you find it.
|
|
||||||
|
|
||||||
I am not a lawyer, but I believe that the Export Control Classification
|
|
||||||
Number (ECCN) for libpng is EAR99, which means not subject to export
|
|
||||||
controls or International Traffic in Arms Regulations (ITAR) because it
|
|
||||||
is open source, publicly available software, that does not contain any
|
|
||||||
encryption software. See the EAR, paragraphs 734.3(b)(3) and 734.7(b).
|
|
||||||
|
|
||||||
If you have any code changes, requests, problems, etc., please e-mail
|
|
||||||
them to me. Also, I'd appreciate any make files or project files,
|
|
||||||
and any modifications you needed to make to get libpng to compile,
|
|
||||||
along with a #define variable to tell what compiler/system you are on.
|
|
||||||
If you needed to add transformations to libpng, or wish libpng would
|
|
||||||
provide the image in a different way, drop me a note (and code, if
|
|
||||||
possible), so I can consider supporting the transformation.
|
|
||||||
Finally, if you get any warning messages when compiling libpng
|
|
||||||
(note: not zlib), and they are easy to fix, I'd appreciate the
|
|
||||||
fix. Please mention "libpng" somewhere in the subject line. Thanks.
|
|
||||||
|
|
||||||
This release was created and will be supported by myself (of course
|
|
||||||
based in a large way on Guy's and Andreas' earlier work), and the PNG
|
|
||||||
development group.

to me. Send me any questions that start with "I was using libpng,

to others, if necessary.
|
|

Please do not send suggestions on how to change PNG. We have

gladly listen. Even if your suggestion is not used immediately,
|
|

it may be used later.

/*
|

TODO - list of things to do for libpng:
|
|
||||||
|
|
||||||
Final bug fixes.
|
|
||||||
Better C++ wrapper/full C++ implementation?
|
|
||||||
Fix problem with C++ and EXTERN "C".
|
|
||||||
cHRM transformation.
|
|
||||||
Remove setjmp/longjmp usage in favor of returning error codes. As a start on
|
|
||||||
this, minimize the use of png_error(), replacing them with
|
|
||||||
png_warning(); return(0); or similar.
|
|
||||||
Palette creation.
|
|
||||||
Add "grayscale->palette" transformation and "palette->grayscale" detection.
|
|
||||||
Improved dithering.
|
|
||||||
Multi-lingual error and warning message support.
|
|
||||||
Complete sRGB transformation (presently it simply uses gamma=0.45455).
|
|
||||||
Man pages for function calls.
|
|
||||||
Better documentation.
|
|
||||||
Better filter selection
|
|
||||||
(counting huffman bits/precompression? filter inertia? filter costs?).
|
|
||||||
Histogram creation.
|
|
||||||
Text conversion between different code pages (Latin-1 -> Mac and DOS).
|
|
||||||
Avoid building gamma tables whenever possible.
|
|
||||||
Use greater precision when changing to linear gamma for compositing against
|
|
||||||
background and doing rgb-to-gray transformation.
|
|
||||||
Investigate pre-incremented loop counters and other loop constructions.
|
|
||||||
Add interpolated method of handling interlacing.
|
|
||||||
Extend pngvalid.c to validate more of the libpng transformations.
|
|
||||||

## (see the conditional assignment to $gccflag above).
|

## There are various ways to get dependency output from gcc. Here's
|
|
||||||
## why we pick this rather obscure method:
|
|
||||||
## - Don't want to use -MD because we'd like the dependencies to end
|
|
||||||
## up in a subdir. Having to rename by hand is ugly.
|
|
||||||
## (We might end up doing this anyway to support other compilers.)
|
|
||||||
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
|
|
||||||
## -MM, not -M (despite what the docs say). Also, it might not be
|
|
||||||
## supported by the other compilers which use the 'gcc' depmode.
|
|
||||||
## - Using -M directly means running the compiler twice (even worse
|
|
||||||
## than renaming).

||||||

|
|
||||||
## This next piece of magic avoids the "deleted header file" problem.
|
|
||||||
## The problem is that when a header file which appears in a .P file
|
|
||||||
## is deleted, the dependency causes make to die (because there is
|
|
||||||
## typically no way to rebuild the header). We avoid this by adding
|
|
||||||
## dummy dependencies for each header file. Too bad gcc doesn't do
|
|
||||||
## this for us directly.
|
|
||||||
## Some versions of gcc put a space before the ':'. On the theory
|
|
||||||
## that the space means something, we add a space to the output as
|
|
||||||
## well. hp depmode also adds that space, but also prefixes the VPATH
|
|
||||||
## to the object. Take care to not repeat it in the output.
|
|

## Some versions of the HPUX 10.20 sed can't process this invocation

## correctly. Breaking it into two sed invocations is a workaround.

.SH NAME
|
|
||||||
png \- Portable Network Graphics (PNG) format
|
|
||||||
.SH DESCRIPTION
|
|
||||||
PNG (Portable Network Graphics) is an extensible file format for the
|
|
||||||
lossless, portable, well-compressed storage of raster images. PNG provides
|
|
||||||
a patent-free replacement for GIF and can also replace many
|
|
||||||
common uses of TIFF. Indexed-color, grayscale, and truecolor images are
|
|
||||||
supported, plus an optional alpha channel. Sample depths range from
|
|
||||||
1 to 16 bits.
|
|
||||||
.br
|
|
||||||
|
|
||||||
PNG is designed to work well in online viewing applications, such as the
|
|
||||||
World Wide Web, so it is fully streamable with a progressive display
|
|
||||||
option. PNG is robust, providing both full file integrity checking and
|
|
||||||
fast, simple detection of common transmission errors. Also, PNG can store
|
|
||||||
gamma and chromaticity data for improved color matching on heterogeneous
|
|
||||||
platforms.

|
||||||
* Normally it is not necessary to specify to the compiler how to call
|
|
||||||
* a function - it just does it - however on x86 systems derived from
|
|
||||||
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
|
|
||||||
* and some others) there are multiple ways to call a function and the
|
|
||||||
* default can be changed on the compiler command line. For this reason
|
|
||||||
* libpng specifies the calling convention of every exported function and
|
|
||||||
* every function called via a user supplied function pointer. This is
|
|
||||||
* done in this file by defining the following macros:
|
|
||||||
*
|
|
||||||
* PNGAPI Calling convention for exported functions.
|
|
||||||
* PNGCBAPI Calling convention for user provided (callback) functions.
|
|
||||||
* PNGCAPI Calling convention used by the ANSI-C library (required
|
|
||||||
* for longjmp callbacks and sometimes used internally to
|
|
||||||
* specify the calling convention for zlib).
|
|
||||||
*
|
|
||||||
* These macros should never be overridden. If it is necessary to
|
|
||||||
* change calling convention in a private build this can be done
|
|
||||||
* by setting PNG_API_RULE (which defaults to 0) to one of the values
|
|
||||||
* below to select the correct 'API' variants.
|
|
||||||
*
|
|
||||||
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
|
|
||||||
* This is correct in every known environment.
|
|
||||||
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
|
|
||||||
* the 'C' calling convention (from PNGCAPI) for
|
|
||||||
* callbacks (PNGCBAPI). This is no longer required
|
|
||||||
* in any known environment - if it has to be used
|
|
||||||
* please post an explanation of the problem to the
|
|
||||||
* libpng mailing list.
|
|
||||||
*
|
|
||||||
* These cases only differ if the operating system does not use the C
|
|
||||||
* calling convention, at present this just means the above cases
|
|
||||||
* (x86 DOS/Windows sytems) and, even then, this does not apply to
|
|
||||||
* Cygwin running on those systems.
|
|
||||||
*
|
|
||||||
* Note that the value must be defined in pnglibconf.h so that what
|
|
||||||
* the application uses to call the library matches the conventions
|
|
||||||
* set when building the library.

/* Symbol export
|
|
||||||
* =============
|
|
||||||
* When building a shared library it is almost always necessary to tell
|
|
||||||
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
|
|
||||||
* is used to mark the symbols. On some systems these symbols can be
|
|
||||||
* extracted at link time and need no special processing by the compiler,
|
|
||||||
* on other systems the symbols are flagged by the compiler and just
|
|
||||||
* the declaration requires a special tag applied (unfortunately) in a
|
|
||||||
* compiler dependent way. Some systems can do either.
|
|
||||||
*
|
|
||||||
* A small number of older systems also require a symbol from a DLL to
|
|
||||||
* be flagged to the program that calls it. This is a problem because
|
|
||||||
* we do not know in the header file included by application code that
|
|
||||||
* the symbol will come from a shared library, as opposed to a statically
|
|
||||||
* linked one. For this reason the application must tell us by setting
|
|
||||||
* the magic flag PNG_USE_DLL to turn on the special processing before
|
|
||||||
* it includes png.h.
|
|
||||||
*
|
|
||||||
* Four additional macros are used to make this happen:
|
|
||||||
*
|
|
||||||
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
|
|
||||||
* the build or imported if PNG_USE_DLL is set - compiler
|
|
||||||
* and system specific.
|
|
||||||
*
|
|
||||||
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
|
|
||||||
* 'type', compiler specific.
|
|
||||||
*
|
|
||||||
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
|
|
||||||
* make a symbol exported from the DLL. Not used in the
|
|
||||||
* public header files; see pngpriv.h for how it is used
|
|
||||||
* in the libpng build.
|
|
||||||
*
|
|
||||||
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
|
|
||||||
* from a DLL - used to define PNG_IMPEXP when
|
|
||||||
* PNG_USE_DLL is set.
|
|
||||||
*/
|
|
||||||
|
|
||||||
/* System specific discovery.
|
|
||||||
* ==========================
|
|
||||||
* This code is used at build time to find PNG_IMPEXP, the API settings
|
|
||||||
* and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
|
|
||||||
* import processing is possible. On Windows systems it also sets
|
|
||||||
* compiler-specific macros to the values required to change the calling
|
|
||||||
* conventions of the various functions.

/* png_info is a structure that holds the information in a PNG file so
|
|
||||||
* that the application can find out the characteristics of the image.
|
|
||||||
* If you are reading the file, this structure will tell you what is
|
|
||||||
* in the PNG file. If you are writing the file, fill in the information
|
|
||||||
* you want to put into the PNG file, using png_set_*() functions, then
|
|
||||||
* call png_write_info().
|
|
||||||
*
|
|
||||||
* The names chosen should be very close to the PNG specification, so
|
|
||||||
* consult that document for information about the meaning of each field.
|
|
||||||
*
|
|
||||||
* With libpng < 0.95, it was only possible to directly set and read the
|
|
||||||
* the values in the png_info_struct, which meant that the contents and
|
|
||||||
* order of the values had to remain fixed. With libpng 0.95 and later,
|
|
||||||
* however, there are now functions that abstract the contents of
|
|
||||||
* png_info_struct from the application, so this makes it easier to use
|
|
||||||
* libpng with dynamic libraries, and even makes it possible to use
|
|
||||||
* libraries that don't have all of the libpng ancillary chunk-handing
|
|
||||||
* functionality. In libpng-1.5.0 this was moved into a separate private
|
|
||||||
* file that is not visible to applications.
|
|
||||||
*
|
|
||||||
* The following members may have allocated storage attached that should be
|
|
||||||
* cleaned up before the structure is discarded: palette, trans, text,
|
|
||||||
* pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
|
|
||||||
* splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
|
|
||||||
* are automatically freed when the info structure is deallocated, if they were
|
|
||||||
* allocated internally by libpng. This behavior can be changed by means
|
|
||||||
* of the png_data_freer() function.
|
|
||||||
*
|
|
||||||
* More allocation details: all the chunk-reading functions that
|
|
||||||
* change these members go through the corresponding png_set_*
|
|
||||||
* functions. A function to clear these members is available: see
|
|
||||||
* png_free_data(). The png_set_* functions do not depend on being
|
|
||||||
* able to point info structure members to any of the storage they are
|
|
||||||
* passed (they make their own copies), EXCEPT that the png_set_text
|
|
||||||
* functions use the same storage passed to them in the text_ptr or
|
|
||||||
* itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
|
|
||||||
* functions do not make their own copies.

# serial 5 lt~obsolete.m4
|
|
||||||
|
|
||||||
# These exist entirely to fool aclocal when bootstrapping libtool.
|
|
||||||
#
|
|
||||||
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
|
|
||||||
# which have later been changed to m4_define as they aren't part of the
|
|
||||||
# exported API, or moved to Autoconf or Automake where they belong.
|
|
||||||
#
|
|
||||||
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
|
|
||||||
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
|
|
||||||
# using a macro with the same name in our local m4/libtool.m4 it'll
|
|
||||||
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
|
|
||||||
# and doesn't know about Autoconf macros at all.)
|
|
||||||
#
|
|
||||||
# So we provide this file, which has a silly filename so it's always
|
|
||||||
# included after everything else. This provides aclocal with the
|
|
||||||
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
|
|
||||||
# because those macros already exist, or will be overwritten later.
|
|
||||||
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
|
|
||||||
#
|
|
||||||
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
|
|
||||||
# Yes, that means every name once taken will need to remain here until
|
|
||||||
# we give up compatibility with versions before 1.7, at which point
|
|
||||||
# we need to keep only those names which we still refer to.
|
|
||||||
|
|
||||||
# This is to help aclocal find these macros, as it can't see m4_define.
