/**
* @file dispatch_common.c
*
* Implements common code shared by the generated GL/EGL/GLX dispatch code.
*
* A collection of some important specs on getting GL function pointers.
*
* From the linux GL ABI (http://www.opengl.org/registry/ABI/):
*
* "3.4. The libraries must export all OpenGL 1.2, GLU 1.3, GLX 1.3, and
* ARB_multitexture entry points statically.
*
* 3.5. Because non-ARB extensions vary so widely and are constantly
* increasing in number, it's infeasible to require that they all be
* supported, and extensions can always be added to hardware drivers
* after the base link libraries are released. These drivers are
* dynamically loaded by libGL, so extensions not in the base
* library must also be obtained dynamically.
*
* 3.6. To perform the dynamic query, libGL also must export an entry
* point called
*
* void (*glXGetProcAddressARB(const GLubyte *))();
*
* The full specification of this function is available separately. It
* takes the string name of a GL or GLX entry point and returns a pointer
* to a function implementing that entry point. It is functionally
* identical to the wglGetProcAddress query defined by the Windows OpenGL
* library, except that the function pointers returned are context
* independent, unlike the WGL query."
*
* From the EGL 1.4 spec:
*
* "Client API function pointers returned by eglGetProcAddress are
* independent of the display and the currently bound client API context,
* and may be used by any client API context which supports the extension.
*
* eglGetProcAddress may be queried for all of the following functions:
*
* • All EGL and client API extension functions supported by the
* implementation (whether those extensions are supported by the current
* client API context or not). This includes any mandatory OpenGL ES
* extensions.
*
* eglGetProcAddress may not be queried for core (non-extension) functions
* in EGL or client APIs 20 .
*
* For functions that are queryable with eglGetProcAddress,
* implementations may choose to also export those functions statically
* from the object libraries im- plementing those functions. However,
* portable clients cannot rely on this behavior.
*
* From the GLX 1.4 spec:
*
* "glXGetProcAddress may be queried for all of the following functions:
*
* • All GL and GLX extension functions supported by the implementation
* (whether those extensions are supported by the current context or
* not).
*
* • All core (non-extension) functions in GL and GLX from version 1.0 up
* to and including the versions of those specifications supported by

libpng-1.6.25-*.asc (armored detached GPG signatures)
Changes since the last public release (1.5.13):
Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
Warn about the incorrect runtime library setting for VS2010 debug DLL builds.
Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
pngrtran.c (Domani Hannes).
Check for png_ptr==NULL earlier in png_zalloc().
Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
Rearranged building of ARM NEON optimizations. The ARM specific code is
split out entirely to the arm subdirectory and changes to configure.ac and
Makefile.am to add new stuff are reduced. Now material code changes,
although for build test purposes, --enable-arm-neon now builds on non-ARM
systems.
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5.
Fixed cases of unquoted DESTDIR in Makefile.am
Fixed a minor bug in types to malloc and major bug in handling compressed
iTXt. Compressed iTXt could not be handled.
Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
Disassembled the version number in scripts/options.awk (necessary for
building on SunOs).
Fixed Windows build issues, enabled ARM compilation. Various warnings issued
by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
GCCs.) ARM support is enabled by default in zlib.props (unsupported by
Microsoft) and ARM compilation is made possible by deleting the check for
x86. The test programs cannot be run because they are not signed.
Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h])
in configure.ac
De-configured build fixes to make a range of deconfiguration options (such
as switching off read or write support) work in more cases. Also upgraded
pngtest and pngvalid to the libpng 1.6 versions (with some modifications)
which provide more extensive testing. Replaced pngtest.png because pngtest
writes the ancillary chunks in a different order.
Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
(Bug report from yuris).
Revised test for validity of "num_unknowns" to eliminate compiler warnings.
Check the validity of the "nentries" parameter of png_set_sPLT() and the
"num_text" parameter of png_set_text_2().
Changes since the last public release (1.6.24):
Reject oversized iCCP profile immediately.
Cleaned up PNG_DEBUG compile of pngtest.c.
Conditionally compile png_inflate().
Don't install pngcp; it conflicts with pngcp in the pngtools package.
Minor editing of INSTALL, (whitespace, added copyright line)
Added MIPS support (Mandar Sahastrabuddhe <Mandar.Sahastrabuddhe@imgtec.com>).
Rebased contrib/intel/intel_sse.patch after the MIPS implementation.

I. Simple installation
On Unix/Linux and similar systems, you can simply type

make install
and ignore the rest of this document.
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 configure does not work on your system and you have a reasonably
up-to-date set of tools, running ./autogen.sh before running ./configure
may fix the problem. You can also run the individual commands in
autogen.sh with the --force option, if supported by your version of
the tools. To be really sure that you aren't using any of the included
pre-built scripts, you can do this:
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
./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

Some also allow you to run "make test-installed" after you have

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.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) 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
this service 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 make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. 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.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
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
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the 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 a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
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
convey 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.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

PNG: The Definitive Guide
===========================
Source Code
Chapters 13, 14 and 15 of "PNG: The Definitive Guide" discuss three free,
cross-platform demo programs that show how to use the libpng reference
library: rpng, rpng2 and wpng. rpng and rpng2 are viewers; the first is
a very simple example that that shows how a standard file-viewer might use
libpng, while the second is designed to process streaming data and shows
how a web browser might be written. wpng is a simple command-line program
that reads binary PGM and PPM files (the ``raw'' grayscale and RGB subsets
of PBMPLUS/NetPBM) and converts them to PNG.
The source code for all three demo programs currently compiles under
Unix, OpenVMS, and 32-bit Windows. (Special thanks to Martin Zinser,
zinser@decus.de, for making the necessary changes for OpenVMS and for
providing an appropriate build script.) Build instructions can be found
below.

Note that, although the programs are designed to be functional, their
primary purpose is to illustrate how to use libpng to add PNG support to
other programs. As such, their user interfaces are crude and definitely
are not intended for everyday use.
Please see http://www.libpng.org/pub/png/pngbook.html for further infor-
mation and links to the latest version of the source code, and Chapters
13-15 of the book for detailed discussion of the three programs.

BUILD INSTRUCTIONS
- Prerequisites (in order of compilation):
- zlib http://zlib.net/
- libpng http://www.libpng.org/pub/png/libpng.html
- pngbook http://www.libpng.org/pub/png/book/sources.html
The pngbook demo programs are explicitly designed to demonstrate proper
coding techniques for using the libpng reference library. As a result,
you need to download and build both zlib (on which libpng depends) and
libpng. A common build setup is to place the zlib, libpng and pngbook
subdirectory trees ("folders") in the same parent directory. Then the
libpng build can refer to files in ../zlib (or ..\zlib or [-.zlib]),
and similarly for the pngbook build.
Note that all three packages are designed to be built from a command
line by default; those who wish to use a graphical or other integrated
development environments are on their own.
- Unix:
Unpack the latest pngbook sources (which should correspond to this
README file) into a directory and change into that directory.
Copy Makefile.unx to Makefile and edit the PNG* and Z* variables
appropriately (possibly also the X* variables if necessary).
make
There is no "install" target, so copy the three executables somewhere
in your path or run them from the current directory. All three will
print a basic usage screen when run without any command-line arguments;
see the book for more details.
- Windows:
Unpack the latest pngbook sources (which should correspond to this
README file) into a folder, open a "DOS shell" or "command prompt"
or equivalent command-line window, and cd into the folder where you
unpacked the source code.
For MSVC, set up the necessary environment variables by invoking
%devstudio%\vc\bin\vcvars32.bat
where where %devstudio% is the installation directory for MSVC /
DevStudio. If you get "environment out of space" errors under 95/98,
create a desktop shortcut with "c:\windows\command.com /e:4096" as
the program command line and set the working directory to the pngbook
directory. Then double-click to open the new DOS-prompt window with
a bigger environment and retry the commands above.
Copy Makefile.w32 to Makefile and edit the PNGPATH and ZPATH variables
appropriately (possibly also the "INC" and "LIB" variables if needed).
Note that the names of the dynamic and static libpng and zlib libraries
used in the makefile may change in later releases of the libraries.
Also note that, as of libpng version 1.0.5, MSVC DLL builds do not work.
This makefile therefore builds statically linked executables, but if
the DLL problems ever get fixed, uncommenting the appropriate PNGLIB
and ZLIB lines will build dynamically linked executables instead.
Do the build by typing
nmake
The result should be three executables: rpng-win.exe, rpng2-win.exe,
and wpng.exe. Copy them somewhere in your PATH or run them from the
current folder. Like the Unix versions, the two windowed programs
(rpng and rpng2) now display a usage screen in a console window when
invoked without command-line arguments; this is new behavior as of
the June 2001 release. Note that the programs use the Unix-style "-"
character to specify options, instead of the more common DOS/Windows
"/" character. (For example: "rpng2-win -bgpat 4 foo.png", not
"rpng2-win /bgpat 4 foo.png")
- OpenVMS:
Unpack the pngbook sources into a subdirectory and change into that
subdirectory.
Edit makevms.com appropriately, specifically the zpath and pngpath
variables.
@makevms
To run the programs, they probably first need to be set up as "foreign
symbols," with "disk" and "dir" set appropriately:
$ rpng == "$disk:[dir]rpng-x.exe"
$ rpng2 == "$disk:[dir]rpng2-x.exe"
$ wpng == "$disk:[dir]wpng.exe"
All three will print a basic usage screen when run without any command-
line arguments; see the book for more details. Note that the options
style is Unix-like, i.e., preceded by "-" rather than "/".
RUNNING THE PROGRAMS: (VERY) BRIEF INTRO
rpng is a simple PNG viewer that can display transparent PNGs with a
specified background color; for example,
rpng -bgcolor \#ff0000 toucan.png
would display the image with a red background. rpng2 is a progressive
viewer that simulates a web browser in some respects; it can display
images against either a background color or a dynamically generated
background image. For example:
rpng2 -bgpat 16 toucan.png
wpng is a purely command-line image converter from binary PBMPLUS/NetPBM
format (.pgm or .ppm) to PNG; for example,
wpng -time < toucan-notrans.ppm > toucan-notrans.png
would convert the specified PPM file (using redirection) to PNG, auto-
matically setting the PNG modification-time chunk.
All options can be abbreviated to the shortest unique value; for example,
"-bgc" for -bgcolor (versus "-bgp" for -bgpat), or "-g" for -gamma.

/*---------------------------------------------------------------------------
rpng - simple PNG display program rpng-win.c
This program decodes and displays PNG images, with gamma correction and
optionally with a user-specified background color (in case the image has
transparency). It is very nearly the most basic PNG viewer possible.
This version is for 32-bit Windows; it may compile under 16-bit Windows
with a little tweaking (or maybe not).
to do:
- handle quoted command-line args (especially filenames with spaces)
- have minimum window width: oh well
- use %.1023s to simplify truncation of title-bar string?
---------------------------------------------------------------------------
Changelog:
- 1.00: initial public release
- 1.01: modified to allow abbreviated options; fixed long/ulong mis-
match; switched to png_jmpbuf() macro
- 1.02: added extra set of parentheses to png_jmpbuf() macro; fixed
command-line parsing bug
- 1.10: enabled "message window"/console (thanks to David Geldreich)
- 2.00: dual-licensed (added GNU GPL)
- 2.01: fixed improper display of usage screen on PNG error(s)

rpng - simple PNG display program rpng-x.c
This program decodes and displays PNG images, with gamma correction and
optionally with a user-specified background color (in case the image has
transparency). It is very nearly the most basic PNG viewer possible.
This version is for the X Window System (tested by author under Unix and
by Martin Zinser under OpenVMS; may work under OS/2 with some tweaking).
to do:
- 8-bit (colormapped) X support
- use %.1023s to simplify truncation of title-bar string?
---------------------------------------------------------------------------
Changelog:
- 1.01: initial public release
- 1.02: modified to allow abbreviated options; fixed long/ulong mis-
match; switched to png_jmpbuf() macro
- 1.10: added support for non-default visuals; fixed X pixel-conversion
- 1.11: added extra set of parentheses to png_jmpbuf() macro; fixed
command-line parsing bug
- 1.12: fixed some small X memory leaks (thanks to François Petitjean)
- 1.13: fixed XFreeGC() crash bug (thanks to Patrick Welche)
- 1.14: added support for X resources (thanks to Gerhard Niklasch)
- 2.00: dual-licensed (added GNU GPL)
- 2.01: fixed improper display of usage screen on PNG error(s)

wpng - simple PNG-writing program wpng.c
This program converts certain NetPBM binary files (grayscale and RGB,
maxval = 255) to PNG. Non-interlaced PNGs are written progressively;
interlaced PNGs are read and written in one memory-intensive blast.
Thanks to Jean-loup Gailly for providing the necessary trick to read
interactive text from the keyboard while stdin is redirected. Thanks
to Cosmin Truta for Cygwin fixes.
NOTE: includes provisional support for PNM type "8" (portable alphamap)
images, presumed to be a 32-bit interleaved RGBA format; no pro-
vision for possible interleaved grayscale+alpha (16-bit) format.
THIS IS UNLIKELY TO BECOME AN OFFICIAL NETPBM ALPHA FORMAT!
to do:
- delete output file if quit before calling any writepng routines
- process backspace with -text option under DOS/Win? (currently get ^H)
---------------------------------------------------------------------------
Changelog:
- 1.01: initial public release
- 1.02: modified to allow abbreviated options
- 1.03: removed extraneous character from usage screen; fixed bug in
command-line parsing
- 1.04: fixed DOS/OS2/Win32 detection, including partial Cygwin fix
(see http://home.att.net/~perlspinr/diffs/GregBook_cygwin.diff)
- 2.00: dual-licensed (added GNU GPL)
[REPORTED BUG (win32 only): "contrib/gregbook/wpng.c - cmd line
dose not work! In order to do something useful I needed to redirect
both input and output, with cygwin and with bcc32 as well. Under
Linux, the same wpng appears to work fine. I don't know what is
the problem."]

This demonstrates the use of PNG_USER_CONFIG, pngusr.h and pngusr.dfa
The makefile builds a minimal read-only decoder with embedded libpng
and zlib.
Specify the location of the zlib source (1.2.1 or later) as ZLIBSRC
on the make command line.
If you prefer to use the shared libraries, go to contrib/pngminus
and build the png2pnm application there.

express or implied warranty.
Some history
------------
Soon after the creation of PNG in 1995, the need was felt for a set of
pnmtopng / pngtopnm utilities. Independantly Alexander Lehmann and I
(Willem van Schaik) started such a project. Luckily we discovered this
and merged the two together into pnmtopng.tar.gz, which is available
from a/o ftp://ftp.simplesystems.org/pub/libpng/png/.
These two utilities have many, many options and make use of most of the
features of PNG, like gamma, alpha, sbit, text-chunks, etc. This makes
the utilities quite complex and by now not anymore very maintainable.
When we wrote these programs, libpng was still in an early stage.
Therefore, lots of the functionality that we put in our software can now
be done using transform-functions in libpng.
Finally, to compile these programs, you need to have installed and
compiled three libraries: libpng, zlib and netpbm. Especially the latter
makes the whole setup a bit bulky. But that's unavoidable given the many
features of pnmtopng.
What now
--------
At this moment libpng is in a very stable state and can do much of the
work done in pnmtopng. Also, pnmtopng needs to be upgraded to the new
interface of libpng. Hence, it is time for a rewrite from the ground up
of pnmtopng and pngtopnm. This will happen in the near future (stay
tuned). The new package will get a different name to distinguish it from
the old one: PngPlus.
To experiment a bit with the new interface of libpng, I started off with
a small prototype that contains only the basic functionality. It doesn't
have any of the options to read or write special chunks and it will do
no gamma correction. But this makes it also a simple program that is
quite easy to understand and can serve well as a template for other
software developments. (By now there are of course a couple of programs,
like Greg Roelofs' rpng/wpng, that can be used just as good.)
Can and can not
---------------
As this is the small brother of the future PngPlus, I called this fellow
PngMinus. Because I started this development in good-old Turbo-C, I
avoided the use the netpbm library, which requires DOS extenders. Again,
another reason to call it PngMinus (minus netpbm :-). So, part of the
program are some elementary routines to read / write pgm- and ppm-files.
It does not read b&w pbm-files.
The downside of this approach is that you can not use them on images
that require blocks of memory bigger than 64k (the DOS version). For
larger images you will get an out-of-memory error.
As said before, PngMinus doesn't correct for gamma. When reading
png-files you can do this just as well by piping the output of png2pnm
to pnmgamma, one of the standard PbmPlus tools. This same scenario will
most probably also be followed in the full-blown future PngPlus, with
the addition of course of the possibility to create gamma-chunks when
writing png-files.
On the other hand it supports alpha-channels. When reading a png-image
you can write the alpha-channel into a pgm-file. And when creating an
RGB+A png-image, you just combine a ppm-file with a corresponding
pgm-file containing the alpha-channel. When reading, transparency chunks
are converted into an alpha-channel and from there on treated the same
way.
Finally you can opt for writing ascii or binary pgm- and ppm-files. When
the bit-depth is 16, the format will always be ascii.
Using it
--------
To distinguish them from pnmtopng and PngPlus, the utilities are named
png2pnm and pnm2png (2 instead of to). The input- and output-files can
be given as parameters or through redirection. Therefore the programs
can be part of a pipe.
To list the options type "png2pnm -h" or "pnm2png -h".
Just like Scandinavian furniture
--------------------------------
You have to put it together yourself. I did test the software under
MS-DOS with Turbo-C 3.0 and under RedHat Linux 4.2 with gcc. In both
cases I used libpng-1.0.4 and zlib-1.1.3. Later versions should be OK,
however some older libpng versions have a bug in pngmem.c when using
Turbo-C 3.0 (see below).
You can build it using one of the two makefiles (make -f makefile.###)
or use the batch/script files pngminus.bat / pngminus.sh. This assumes
that you have built the libraries in ../libpng and ../zlib. Using Linux,
make sure that you have built libpng with makefile.std and not
makefile.linux (also called .lnx in earlier versions of libpng). The
latter creates a .so shared-library, while the PngMinus makefile assumes
a normal .a static library.
If you create a ../pngsuite directory and then store the basn####.png
files from PngSuite (http://www.schaik.com/pngsuite/) in there, you can
test in one go the proper functioning of PngMinus, see png2pnm.bat and
pnm2png.bat (or the .sh versions).
Warranty
-------
Please, remember that this was just a small experiment to learn a few
things. It will have many unforeseen features <vbg>. Who said bugs? Use
it when you are in need for something simple or when you want to start
developing your own stuff.
The Turbo bug
-------------
** pngmem.old
hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L);
hptr += 16L;
** pngmem.c
hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L);
hptr = hptr + 16L;
**
** pngmem.old
png_ptr->offset_table_ptr[i] = (png_bytep)hptr;
hptr += (png_uint_32)65536L;
** pngmem.c
png_ptr->offset_table_ptr[i] = (png_bytep)hptr;
hptr = hptr + 65536L;
**
