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 https://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. Enabling or disabling hardware optimizations

Certain hardware capabilities, such as the Intel SSE instructions,
are normally detected at run time. Enable them with configure options
such as one of

   --enable-arm-neon=yes
   --enable-mips-msa=yes
   --enable-intel-sse=yes
   --enable-powerpc-vsx=yes

or enable them all at once with

   --enable-hardware-optimizations=yes

or, if you are not using "configure", you can use one
or more of

   CPPFLAGS += "-DPNG_ARM_NEON"
   CPPFLAGS += "-DPNG_MIPS_MSA"
   CPPFLAGS += "-DPNG_INTEL_SSE"
   CPPFLAGS += "-DPNG_POWERPC_VSX"

See for example scripts/makefile.linux-opt

If you wish to avoid using them,
you can disable them via the configure option

   --disable-hardware-optimizations

to disable them all, or

   --enable-intel-sse=no

to disable a particular one,
or via compiler-command options such as

   CPPFLAGS += "-DPNG_ARM_NEON_OPT=0, -DPNG_MIPS_MSA_OPT=0,
   -DPNG_INTEL_SSE_OPT=0, -DPNG_POWERPC_VSX_OPT=0"

If you are using cmake, hardware optimizations are "on"
by default. To disable them, use

    cmake . -DPNG_ARM_NEON=no -DPNG_INTEL_SSE=no \
            -DPNG_MIPS_MSA=no -DPNG_POWERPC_VSX=no

or disable them all at once with

    cmake . -DPNG_HARDWARE_OPTIMIZATIONS=no

XV. 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.

XVI. 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.

XVII. 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.

XVIII. Other sources of information about libpng:

Further information can be found in the README and libpng-manual.txt
files, in the individual makefiles, in png.h, and the manual pages
libpng.3 and png.5.

README for libpng version 1.6.37 - April 14, 2019
=================================================

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 the 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.

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 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
https://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/pngdocs.html .

This code is currently being archived at libpng.sourceforge.io in the
[DOWNLOAD] area, and at http://libpng.download/src .

This release, based in a large way on Glenn's, Guy's and Andreas'
earlier work, was created and will be supported by myself and the PNG
development group.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory.  The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run.  This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
#    fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
#    fails if $ac_aux_dir is absolute,
#    fails when called from a subdirectory in a VPATH build with
#          a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir.  In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
#   MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH.  The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# Run 'autoreconf' to build 'configure', 'Makefile.in' and other configure
# control files.
#
# The first time this is run on a GIT checkout the only files that exist are
# configure.ac and Makefile.am; all of the autotools support scripts are
# missing.  They are instantiated with autoreconf --force --install.
#
# For regular ("tarball") distributions all the files should exist.  We do not
# want them to be updated *under any circumstances*.  It should never be
# necessary to run autogen.sh because ./configure --enable-maintainer-mode says
# what to do if Makefile.am or configure.ac are changed.
#
# It is *probably* OK to update the files on a GIT checkout, because they have
# come from the local tools, but leave that to the user who is assumed to know
# whether it is ok or required.
#
# This script is intended to work without arguments, there are, however, hidden
# arguments (a) for use while testing the script and (b) to fix up systems that

OPERATING SYSTEM SPECIFIC ARM NEON DETECTION
--------------------------------------------

Detection of the ability to execute ARM NEON on an ARM processor requires
operating system support.  (The information is not available in user mode.)

HOW TO USE THIS
---------------

This directory contains C code fragments that can be included in arm/arm_init.c
by setting the macro PNG_ARM_NEON_FILE to the file name in "" or <> at build
time.  This setting is not recorded in pnglibconf.h and can be changed simply by
rebuilding arm/arm_init.o with the required macro definition.

For any of this code to be used the ARM NEON code must be enabled and run time
checks must be supported.  I.e.:

#if PNG_ARM_NEON_OPT > 0
#ifdef PNG_ARM_NEON_CHECK_SUPPORTED

This is done in a 'configure' build by passing configure the argument:

   --enable-arm-neon=check

Apart from the basic Linux implementation in contrib/arm-neon/linux.c this code
is unsupported.  That means that it is not even compiled on a regular basis and
may be broken in any given minor release.

FILE FORMAT
-----------

Each file documents its testing status as of the last time it was tested (which
may have been a long time ago):

STATUS: one of:
   SUPPORTED: This indicates that the file is included in the regularly
         performed test builds and bugs are fixed when discovered.
   COMPILED: This indicates that the code did compile at least once.  See the
         more detailed description for the extent to which the result was
         successful.
   TESTED: This means the code was fully compiled into the libpng test programs
         and these were run at least once.

BUG REPORTS: an email address to which to send reports of problems

The file is a fragment of C code. It should not define any 'extern' symbols;
everything should be static.  It must define the function:

static int png_have_neon(png_structp png_ptr);

That function must return 1 if ARM NEON instructions are supported, 0 if not.
It must not execute png_error unless it detects a bug.  A png_error will prevent
the reading of the PNG and in the future, writing too.

BUG REPORTS
-----------

If you mail a bug report for any file that is not SUPPORTED there may only be
limited response.  Consider fixing it and sending a patch to fix the problem -
this is more likely to result in action.

CONTRIBUTIONS
-------------

You may send contributions of new implementations to
png-mng-implement@sourceforge.net.  Please write code in strict C90 C where
possible.  Obviously OS dependencies are to be expected.  If you submit code you
must have the authors permission and it must have a license that is acceptable
to the current maintainer; in particular that license must permit modification
and redistribution.

Please try to make the contribution a single file and give the file a clear and
unambiguous name that identifies the target OS.  If multiple files really are
required put them all in a sub-directory.

You must also be prepared to handle bug reports from users of the code, either
by joining the png-mng-implement mailing list or by providing an email for the
"BUG REPORTS" entry or both.  Please make sure that the header of the file
contains the STATUS and BUG REPORTS fields as above.

Please list the OS requirements as precisely as possible.  Ideally you should
also list the environment in which the code has been tested and certainly list
any environments where you suspect it might not work.

This directory contains test configuration files, currently always '.dfa' files
intended to be used in the build by setting the make macro DFA_XTRA to the name
of the file.

These files are used in release validation of the 'configure' builds of libpng
by building 'make check', or 'make all-am' for cross-builds, with each .dfa
file.

The files in this directory may change between minor releases, however
contributions describing specific builds of libpng are welcomed.  There is no
guarantee that libpng will continue to build with such configurations; support
for given configurations can be, and has been, dropped between successive minor
releases.  However if a .dfa file describing a configuration is not in this
directory it is very unlikely that it will be tested before a minor release!

You can use these .dfa files as the basis of new configurations.  Files in this
directory should not have any use restrictions or restrictive licenses.

This directory is not included in the .zip and .7z distributions, which do
not contain 'configure' scripts.

DOCUMENTATION
=============

Examples:
   ${srcdir}/pngusr.dfa
   ${srcdir}/contrib/pngminim/*/pngusr.dfa

Documentation of the options:
   ${srcdir}/scripts/pnglibconf.dfa

Documentation of the file format:
   ${srcdir}/scripts/options.awk

FILE NAMING
===========

File names in this directory may NOT contain any of the five characters:

   - , + * ?

Neither may they contain any space character.

While other characters may be used it is strongly suggested that file names be
limited to lower case Latiin alphabetic characters (a-z), digits (0-9) and, if
necessary the underscore (_) character.  File names should be about 8 characters
long (excluding the .dfa extension).  Submitted .dfa files should have names
between 7 and 16 characters long, shorter names (6 characters or less) are
reserved for standard tests.

			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 https://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. Enabling or disabling hardware optimizations

			Certain hardware capabilities, such as the Intel SSE instructions,
			are normally detected at run time. Enable them with configure options
			such as one of

			--enable-arm-neon=yes
			--enable-mips-msa=yes
			--enable-intel-sse=yes
			--enable-powerpc-vsx=yes

			or enable them all at once with

			--enable-hardware-optimizations=yes

			or, if you are not using "configure", you can use one
			or more of

			CPPFLAGS += "-DPNG_ARM_NEON"
			CPPFLAGS += "-DPNG_MIPS_MSA"
			CPPFLAGS += "-DPNG_INTEL_SSE"
			CPPFLAGS += "-DPNG_POWERPC_VSX"

			See for example scripts/makefile.linux-opt

			If you wish to avoid using them,
			you can disable them via the configure option

			--disable-hardware-optimizations

			to disable them all, or

			--enable-intel-sse=no

			to disable a particular one,
			or via compiler-command options such as

			CPPFLAGS += "-DPNG_ARM_NEON_OPT=0, -DPNG_MIPS_MSA_OPT=0,
			-DPNG_INTEL_SSE_OPT=0, -DPNG_POWERPC_VSX_OPT=0"

			If you are using cmake, hardware optimizations are "on"
			by default. To disable them, use

			cmake . -DPNG_ARM_NEON=no -DPNG_INTEL_SSE=no \
			-DPNG_MIPS_MSA=no -DPNG_POWERPC_VSX=no

			or disable them all at once with

			cmake . -DPNG_HARDWARE_OPTIMIZATIONS=no

			XV. 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.

			XVI. 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.

			XVII. 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.

			XVIII. Other sources of information about libpng:

			Further information can be found in the README and libpng-manual.txt
			files, in the individual makefiles, in png.h, and the manual pages
			libpng.3 and png.5.

			README for libpng version 1.6.37 - April 14, 2019
			=================================================

			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 the 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.

			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 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
			https://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/pngdocs.html .

			This code is currently being archived at libpng.sourceforge.io in the
			[DOWNLOAD] area, and at http://libpng.download/src .

			This release, based in a large way on Glenn's, Guy's and Andreas'
			earlier work, was created and will be supported by myself and the PNG
			development group.

			TODO - list of things to do for libpng:

			* Fix all defects (duh!)
			* Better C++ wrapper / full C++ implementation (?)
			* Fix the problems with C++ and 'extern "C"'.
			* cHRM transformation.
			* Palette creation.
			* "grayscale->palette" transformation and "palette->grayscale" detection.
			* Improved dithering.
			* Multi-lingual error and warning message support.
			* Complete sRGB transformation. (Currently it simply uses gamma=0.45455.)
			* Man pages for function calls.
			* Better documentation.
			* Better filter selection
			(e.g., counting huffman bits/precompression; filter inertia; filter costs).
			* Histogram creation.
			* Text conversion between different code pages (e.g., Latin-1 -> Mac).
			* Avoid building gamma tables whenever possible.
			* Greater precision in changing to linear gamma for compositing against
			background, and in doing rgb-to-gray transformations.
			* Investigate pre-incremented loop counters and other loop constructions.
			* Interpolated method of handling interlacing.
			* More validations for libpng transformations.
