Libpng 1.6.17 - March 26, 2015
This is a public release of libpng, intended for use in production codes.
Files available for download:
Source files with LF line endings (for Unix/Linux) and with a
"configure" script
libpng-1.6.17.tar.xz (LZMA-compressed, recommended)
libpng-1.6.17.tar.gz
Source files with CRLF line endings (for Windows), without the
"configure" script
lpng1617.7z (LZMA-compressed, recommended)
lpng1617.zip
Other information:
libpng-1.6.17-README.txt
libpng-1.6.17-LICENSE.txt
libpng-1.6.17-*.asc (armored detached GPG signatures)
Changes since the last public release (1.6.16):
Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
Corrected the width limit calculation in png_check_IHDR().
Removed user limits from pngfix. Also pass NULL pointers to
png_read_row to skip the unnecessary row de-interlace stuff.
Added testing of png_set_packing() to pngvalid.c
Regenerated configure scripts in the *.tar distributions with libtool-2.4.4
Implement previously untested cases of libpng transforms in pngvalid.c
Fixed byte order in 2-byte filler, in png_do_read_filler().
Made the check for out-of-range values in png_set_tRNS() detect
values that are exactly 2^bit_depth, and work on 16-bit platforms.
Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
pngset.c to avoid warnings about dead code.
Do not build png_product2() when it is unused.
Display user limits in the output from pngtest.
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
and 1-million-row default limits in pnglibconf.dfa, that can be reset
by the user at build time or run time. This provides a more robust
defense against DOS and as-yet undiscovered overflows.
Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
of png.h.
Avoid runtime checks when converting integer to png_byte with
Visual Studio (Sergey Kosarevsky)
Removed some comments that the configure script did not handle
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
Free the unknown_chunks structure even when it contains no data.
Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
for consistency, and remove some useless tests (Alexey Petruchik).
Remove pnglibconf.h, pnglibconf.c, pnglibconf.pre, pnglibconf.dfn,
and pnglibconf.out instead of pnglibconf.* in "make clean" (Cosmin).
Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
value was wrong. It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).

1.6.3beta01.
Version 1.6.2 [April 25, 2013]
No changes.
Version 1.6.3beta01 [April 25, 2013]
Revised stack marking in arm/filter_neon.S and configure.ac.
Ensure that NEON filter stuff is completely disabled when switched 'off'.
Previously the ARM NEON specific files were still built if the option
was switched 'off' as opposed to being explicitly disabled.
Version 1.6.3beta02 [April 26, 2013]
Test for 'arm*' not just 'arm' in the host_cpu configure variable.
Rebuilt the configure scripts.
Version 1.6.3beta03 [April 30, 2013]
Expanded manual paragraph about writing private chunks, particularly
the need to call png_set_keep_unknown_chunks() when writing them.
Avoid dereferencing NULL pointer possibly returned from
png_create_write_struct() (Andrew Church).
Version 1.6.3beta05 [May 9, 2013]
Calculate our own zlib windowBits when decoding rather than trusting the
CMF bytes in the PNG datastream.
Added an option to force maximum window size for inflating, which was
the behavior of libpng15 and earlier.
Added png-fix-itxt and png-fix-too-far-back to the built programs and
removed warnings from the source code and timepng that are revealed as
a result.
Detect wrong libpng versions linked to png-fix-too-far-back, which currently
only works with libpng versions that can be made to reliably fail when
the deflate data contains an out-of-window reference. This means only
1.6 and later.
Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
message which it is easier to work round than ignore.
Updated contrib/pngminus/pnm2png.c (Paul Stewart):
Check for EOF
Ignore "#" delimited comments in input file to pnm2png.c.
Fixed whitespace handling
Added a call to png_set_packing()
Initialize dimension values so if sscanf fails at least we have known
invalid values.
Attempt to detect configuration issues with png-fix-too-far-back, which
requires both the correct libpng and the correct zlib to function
correctly.
Check ZLIB_VERNUM for mismatches, enclose #error in quotes
Added information in the documentation about problems with and fixes for
the bad CRC and bad iTXt chunk situations.
Version 1.6.3beta06 [May 12, 2013]
Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and
WRITE_PACK supported (writes error message that it can't read P1 or
P4 PBM files).
Improved png-fix-too-far-back usage message, added --suffix option.
Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the
right zlib header files.
Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile
Version 1.6.3beta07 [June 8, 2013]
Removed a redundant test in png_set_IHDR().
Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt)
Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt
Enclose the prototypes for the simplified write API in
#ifdef PNG_STDIO_SUPPORTED/#endif
Make ARM NEON support work at compile time (not just configure time).
This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
using a compiler that compiles for multiple architectures at one time.
Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from
pnglibconf.h, allowing more of the decisions to be made internally
(pngpriv.h) during the compile. Without this, symbol prefixing is broken
under certain circumstances on ARM platforms. Now only the API parts of
the optimizations ('check' vs 'api') are exposed in the public header files
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
decision about whether or not to use the optimizations.
Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage.
Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
on __ARM_NEON__ from configure time to compile time. This breaks symbol
prefixing because the definition of the special png_init_filter_functions
call was hidden at configure time if the relevant compiler arguments are
passed in CFLAGS as opposed to CC. This change attempts to avoid all
the confusion that would result by declaring the init function even when
it is not used, so that it will always get prefixed.
Version 1.6.3beta08 [June 18, 2013]
Revised libpng.3 so that "doclifter" can process it.
Version 1.6.3beta09 [June 27, 2013]
Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18
as parameters for png_set_gamma(). These have been available since
libpng-1.5.4.
Renamed contrib/tools/png-fix-too-far-back.c to pngfix.c and revised it
to check all compressed chunks known to libpng.
Version 1.6.3beta10 [July 5, 2013]
Updated documentation to show default behavior of benign errors correctly.
Only compile ARM code when PNG_READ_SUPPORTED is defined.
Fixed undefined behavior in contrib/tools/pngfix.c and added new strip
option. pngfix relied on undefined behavior and even a simple change from
gcc to g++ caused it to fail. The new strip option 'unsafe' has been
implemented and is the default if --max is given. Option names have
been clarified, with --strip=transform now stripping the bKGD chunk,
which was stripped previously with --strip=unused.
Added all documented chunk types to pngpriv.h
Unified pngfix.c source with libpng17.
Version 1.6.3rc01 [July 11, 2013]
No changes.
Version 1.6.3 [July 18, 2013]
Revised manual about changes in iTXt chunk handling made in libpng-1.6.0.
Added "/* SAFE */" comments in pngrutil.c and pngrtran.c where warnings
may be erroneously issued by code-checking applications.
Version 1.6.4beta01 [August 21, 2013]
Added information about png_set_options() to the manual.
Delay calling png_init_filter_functions() until a row with nonzero filter
is found.
Version 1.6.4beta02 [August 30, 2013]
Fixed inconsistent conditional compilation of png_chunk_unknown_handling()
prototype, definition, and usage. Made it depend on
PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.
Version 1.6.4rc01 [September 5, 2013]
No changes.
Version 1.6.4 [September 12, 2013]
No changes.
Version 1.6.5 [September 14, 2013]
Removed two stray lines of code from arm/arm_init.c.
Version 1.6.6 [September 16, 2013]
Removed two stray lines of code from arm/arm_init.c, again.
Version 1.6.7beta01 [September 30, 2013]
Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE
combination
Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also
fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of
Gentoo).
Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of
png_modifier are greater than that of png_store and as a consequence
compilation of pngvalid.c results in a warning about increased alignment
requirements because of the bare cast to (png_modifier*). The code is safe,
because the pointer is known to point to a stack allocated png_modifier,
but this change avoids the warning.
Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
compiled without the CHECK option it defaulted to on, not off.
Check user callback behavior in pngunknown.c. Previous versions compiled
if SAVE_UNKNOWN was not available but did nothing since the callback
was never implemented.
Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
Version 1.6.7beta02 [October 12, 2013]
Made changes for compatibility with automake 1.14:
1) Added the 'compile' program to the list of programs that must be cleaned
in autogen.sh
2) Added 'subdir-objects' which causes .c files in sub-directories to be
compiled such that the corresponding .o files are also in the
sub-directory. This is because automake 1.14 warns that the
current behavior of compiling to the top level directory may be removed
in the future.
3) Updated dependencies on pnglibconf.h to match the new .o locations and
added all the files in contrib/libtests and contrib/tools that depend
on pnglibconf.h
4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
way of handling the dependencies of sources that are machine generated;
unfortunately it only works if the user does 'make all' or 'make check',
so the dependencies (3) are still required.
Cleaned up (char*) casts of zlib messages. The latest version of the Intel C
compiler complains about casting a string literal as (char*), so copied the
treatment of z_const from the library code into pngfix.c
Simplified error message code in pngunknown. The simplification has the
useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always
removing the 1.14 'compile' script but never checking for it.
Version 1.6.7beta03 [October 19, 2013]
Added ARMv8 support (James Yu <james.yu at linaro.org>). Added file
arm/filter_neon_intrinsics.c; enable with -mfpu=neon.
Revised pngvalid to generate size images with as many filters as it can
manage, limited by the number of rows.
Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h
and detect the broken GCC compilers.
Version 1.6.7beta04 [October 26, 2013]
Allow clang derived from older GCC versions to use ARM intrinsics. This
causes all clang builds that use -mfpu=neon to use the intrinsics code,
not the assembler code. This has only been tested on iOS 7. It may be
necessary to exclude some earlier clang versions but this seems unlikely.
Changed NEON implementation selection mechanism. This allows assembler
or intrinsics to be turned on at compile time during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro
is undefined by default and the build type is selected in pngpriv.h.
Version 1.6.7rc01 [November 2, 2013]
No changes.
Version 1.6.7rc02 [November 7, 2013]
Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char
checking macros take an unsigned char argument, not a signed char.
Version 1.6.7 [November 14, 2013]
No changes.
Version 1.6.8beta01 [November 24, 2013]
Moved prototype for png_handle_unknown() in pngpriv.h outside of
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
Conditionally compile some unused functions reported by -Wall in
pngminim.
Fixed 'minimal' builds. Various obviously useful minimal configurations
don't build because of missing contrib/libtests test programs and
overly complex dependencies in scripts/pnglibconf.dfa. This change
adds contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.
Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().
Version 1.6.8beta02 [November 30, 2013]
Removed or marked PNG_UNUSED some harmless "dead assignments" reported
by clang scan-build.
Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
to '"%s" m' to improve portability among compilers.
Changed png_free_default() to free() in pngtest.c
Version 1.6.8rc01 [December 12, 2013]
Tidied up pngfix inits and fixed pngtest no-write builds.
Version 1.6.8rc02 [December 14, 2013]
Handle zero-length PLTE chunk or NULL palette with png_error()
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
and VU#650142. Libpng-1.6.1 through 1.6.7 are vulnerable.
Libpng-1.6.0 and earlier do not have this bug.
Version 1.6.8 [December 19, 2013]
No changes.
Version 1.6.9beta01 [December 26, 2013]
Bookkeeping: Moved functions around (no changes). Moved transform
function definitions before the place where they are called so that
they can be made static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c
Made transform implementation functions static. This makes the internal
functions called by png_do_{read|write}_transformations static. On an
x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.
Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
in the tar distributions.
Version 1.6.9beta02 [January 1, 2014]
Added checks for libpng 1.5 to pngvalid.c. This supports the use of
this version of pngvalid in libpng 1.5
Merged with pngvalid.c from libpng-1.7 changes to create a single
pngvalid.c
Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner).
Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0
Merged libpng-1.7.0 changes to make no-interlace configurations work
with test programs.
Revised pngvalid.c to support libpng 1.5, which does not support the
PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
pngvalid.c
Allow unversioned links created on install to be disabled in configure.
In configure builds 'make install' changes/adds links like png.h
and libpng.a to point to the newly installed, versioned, files (e.g.
libpng17/png.h and libpng17.a). Three new configure options and some
rearrangement of Makefile.am allow creation of these links to be disabled.
Version 1.6.9beta03 [January 10, 2014]
Removed potentially misleading warning from png_check_IHDR().
Version 1.6.9beta04 [January 20, 2014]
Updated scripts/makefile.* to use CPPFLAGS (Cosmin).
Added clang attribute support (Cosmin).
Version 1.6.9rc01 [January 28, 2014]
No changes.
Version 1.6.9rc02 [January 30, 2014]
Quiet an uninitialized memory warning from VC2013 in png_get_png().
Version 1.6.9 [February 6, 2014]
Version 1.6.10beta01 [February 9, 2014]
Backported changes from libpng-1.7.0beta30 and beta31:
Fixed a large number of instances where PNGCBAPI was omitted from
function definitions.
Added pngimage test program for png_read_png() and png_write_png()
with two new test scripts.
Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
png_set_packing() in png_read_png().
Fixed combination of ~alpha with shift. On read invert alpha, processing
occurred after shift processing, which causes the final values to be
outside the range that should be produced by the shift. Reversing the
order on read makes the two transforms work together correctly and mirrors
the order used on write.
Do not read invalid sBIT chunks. Previously libpng only checked sBIT
values on write, so a malicious PNG writer could therefore cause
the read code to return an invalid sBIT chunk, which might lead to
application errors or crashes. Such chunks are now skipped (with
chunk_benign_error).
Make png_read_png() and png_write_png() prototypes in png.h depend
upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
Support builds with unsupported PNG_TRANSFORM_* values. All of the
PNG_TRANSFORM_* values are always defined in png.h and, because they
are used for both read and write in some cases, it is not reliable
to #if out ones that are totally unsupported. This change adds error
detection in png_read_image() and png_write_image() to do a
png_app_error() if the app requests something that cannot be done
and it adds corresponding code to pngimage.c to handle such options
by not attempting to test them.
Version 1.6.10beta02 [February 23, 2014]
Moved redefines of png_error(), png_warning(), png_chunk_error(),
and png_chunk_warning() from pngpriv.h to png.h to make them visible
to libpng-calling applications.
Moved OS dependent code from arm/arm_init.c, to allow the included
implementation of the ARM NEON discovery function to be set at
build-time and provide sample implementations from the current code in the
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
compile and link on Android by using /proc/cpuinfo, and the old linux code
is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux
dependencies apart from opening /proc/cpuinfo and is C90 compliant.
Check for info_ptr == NULL early in png_read_end() so we don't need to
run all the png_handle_*() and depend on them to return if info_ptr == NULL.
This improves the performance of png_read_end(png_ptr, NULL) and makes
it more robust against future programming errors.
Check for __has_extension before using it in pngconf.h, to
support older Clang versions (Jeremy Sequoia).
Treat CRC error handling with png_set_crc_action(), instead of with
png_set_benign_errors(), which has been the case since libpng-1.6.0beta18.
Use a user warning handler in contrib/gregbook/readpng2.c instead of default,
so warnings will be put on stderr even if libpng has CONSOLE_IO disabled.
Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk
after recognizing the IDAT chunk, which avoids an infinite loop while
reading a datastream whose first IDAT chunk is of zero-length.
This fixes CERT VU#684412 and CVE-2014-0333.
Don't recognize known sRGB profiles as sRGB if they have been hacked,
but don't reject them and don't issue a copyright violation warning.
Version 1.6.10beta03 [February 25, 2014]
Moved some documentation from png.h to libpng.3 and libpng-manual.txt
Minor editing of contrib/arm-neon/README and contrib/examples/*.c
Version 1.6.10rc01 [February 27, 2014]
Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
and PNG_USR_CONFIG -> PNG_USER_CONFIG).
Version 1.6.10rc02 [February 28, 2014]
Removed unreachable return statement after png_chunk_error()
in pngrutil.c
Version 1.6.10rc03 [March 4, 2014]
Un-deprecated png_data_freer().
Version 1.6.10 [March 6, 2014]
No changes.
Version 1.6.11beta01 [March 17, 2014]
Use "if (value != 0)" instead of "if (value)" consistently.
Changed ZlibSrcDir from 1.2.5 to 1.2.8 in projects/vstudio.
Moved configuration information from the manual to the INSTALL file.
Version 1.6.11beta02 [April 6, 2014]
Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because
they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3
when using its "__builtin_pow()" function.
Silence 'unused parameter' build warnings (Cosmin Truta).
$(CP) is now used alongside $(RM_F). Also, use 'copy' instead of 'cp'
where applicable, and applied other minor makefile changes (Cosmin).
Don't warn about invalid dimensions exceeding user limits (Cosmin).
Allow an easy replacement of the default pre-built configuration
header with a custom header, via the make PNGLIBCONF_H_PREBUILT
macro (Cosmin).
Version 1.6.11beta03 [April 6, 2014]
Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes
with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss).
Optionally use __builtin_bswap16() in png_do_swap().
Version 1.6.11beta04 [April 19, 2014]
Made progressive reading of interlaced images consistent with the
behavior of the sequential reader and consistent with the manual, by
moving some code out of the PNG_READ_INTERLACING_SUPPORTED blocks. The
row_callback now receives the proper pass number and unexpanded rows, when
png_combine_row() isn't built or used, and png_set_interlace_handling()
is not called.
Allow PNG_sRGB_PROFILE_CHECKING = (-1) to mean no sRGB profile checking.
Version 1.6.11beta05 [April 26, 2014]
Do not reject ICC V2 profiles that lack padding (Kai-Uwe Behrmann).
Relocated closing bracket of the sRGB profile test loop to avoid getting
"Not recognizing known sRGB profile that has been edited" warning for
ICC V2 profiles that lack the MD5 signature in the profile header.
Version 1.6.11beta06 [May 19, 2014]
Added PNG_SKIP_sRGB_CHECK_PROFILE choice for png_set_option().
Version 1.6.11rc01 [May 27, 2014]
No changes.
Version 1.6.11rc02 [June 3, 2014]
Test ZLIB_VERNUM instead of PNG_ZLIB_VERNUM in contrib/tools/pngfix.c
Version 1.6.11 [June 5, 2014]
No changes.
Version 1.6.12rc01 [June 6, 2014]
Relocated new code from 1.6.11beta06 in png.c to a point after the
declarations (Max Stepin).
Version 1.6.12rc02 [June 7, 2014]
Changed file permissions of contrib/tools/intgamma.sh,
test-driver, and compile from 0644 to 0755 (Cosmin).
Version 1.6.12rc03 [June 8, 2014]
Ensure "__has_attribute()" macro exists before trying to use it with
old clang compilers (MacPorts Ticket #43939).
Version 1.6.12 [June 12, 2014]
No changes.
Version 1.6.13beta01 [July 4, 2014]
Quieted -Wsign-compare and -Wclobber compiler warnings in
contrib/pngminus/*.c
Added "(void) png_ptr;" where needed in contrib/gregbook to quiet
compiler complaints about unused pointers.
Split a long output string in contrib/gregbook/rpng2-x.c.
Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa,
Needed for write-only support (John Bowler).
Changed "if defined(__ARM_NEON__)" to
"if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu).
Fixed clang no-warning builds: png_digit was defined but never used.
Version 1.6.13beta02 [July 21, 2014]
Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32
(bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11.
Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and
makefile.tc3 similarly.
Version 1.6.13beta03 [August 3, 2014]
Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14
due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT
definitions from pngconf.h.
Ensure that CMakeLists.txt makes the target "lib" directory before making
symbolic link into it (SourceForge bug report #226 by Rolf Timmermans).
Version 1.6.13beta04 [August 8, 2014]
Added opinion that the ECCN (Export Control Classification Number) for
libpng is EAR99 to the README file.
Eliminated use of "$<" in makefile explicit rules, when copying
$PNGLIBCONF_H_PREBUILT. This does not work on some versions of make;
bug introduced in libpng version 1.6.11.
Version 1.6.13rc01 [August 14, 2014]
Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu
Version 1.6.13 [August 21, 2014]
No changes.
Version 1.6.14beta01 [September 14, 2014]
Guard usage of png_ptr->options with #ifdef PNG_SET_OPTION_SUPPORTED.
Do not build contrib/tools/pngfix.c when PNG_SETJMP_NOT_SUPPORTED,
to allow "make" to complete without setjmp support (bug report by
Claudio Fontana)
Add "#include <setjmp.h>" to contrib/tools/pngfix.c (John Bowler)
Version 1.6.14beta02 [September 18, 2014]
Use nanosleep() instead of usleep() in contrib/gregbook/rpng2-x.c
because usleep() is deprecated.
Define usleep() in contrib/gregbook/rpng2-x.c if not already defined
in unistd.h and nanosleep() is not available; fixes error introduced
in libpng-1.6.13.
Disable floating point exception handling in pngvalid.c when
PNG_FLOATING_ARITHMETIC is not supported (bug report by "zootus
at users.sourceforge.net").
Version 1.6.14beta03 [September 19, 2014]
Define FE_DIVBYZERO, FE_INVALID, and FE_OVERFLOW in pngvalid.c if not
already defined. Revert floating point exception handling in pngvalid.c
to version 1.6.14beta01 behavior.
Version 1.6.14beta04 [September 27, 2014]
Fixed incorrect handling of the iTXt compression flag in pngrutil.c
(bug report by Shunsaku Hirata). Bug was introduced in libpng-1.6.0.
Version 1.6.14beta05 [October 1, 2014]
Added "option READ_iCCP enables READ_COMPRESSED_TEXT" to pnglibconf.dfa
Version 1.6.14beta06 [October 5, 2014]
Removed unused "text_len" parameter from private function png_write_zTXt().
Conditionally compile some code in png_deflate_claim(), when
PNG_WARNINGS_SUPPORTED and PNG_ERROR_TEXT_SUPPORTED are disabled.
Replaced repeated code in pngpread.c with PNG_PUSH_SAVE_BUFFER_IF_FULL.
Added "chunk iTXt enables TEXT" and "chunk zTXt enables TEXT"
to pnglibconf.dfa.
Removed "option READ_COMPRESSED_TEXT enables READ_TEXT" from pnglibconf.dfa,
to make it possible to configure a libpng that supports iCCP but not TEXT.
Version 1.6.14beta07 [October 7, 2014]
Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa
Only mark text chunks as written after successfully writing them.
Version 1.6.14rc01 [October 15, 2014]
Fixed some typos in comments.
Version 1.6.14rc02 [October 17, 2014]
Changed png_convert_to_rfc_1123() to png_convert_to_rfc_1123_buffer()
in the manual, to reflect the change made in libpng-1.6.0.
Updated README file to explain that direct access to the png_struct
and info_struct members has not been permitted since libpng-1.5.0.
Version 1.6.14 [October 23, 2014]
No changes.
Version 1.6.15beta01 [October 29, 2014]
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
Simplified png_free_data().
Added missing "ptr = NULL" after some instances of png_free().
Version 1.6.15beta02 [November 1, 2014]
Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
Version 1.6.15beta03 [November 3, 2014]
Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz).
Version 1.6.15beta04 [November 4, 2014]
Removed new PNG_USE_ARM_NEON configuration flag and made a one-line
revision to configure.ac to support ARM on aarch64 instead (John Bowler).
Version 1.6.15beta05 [November 5, 2014]
Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in
example.c, pngtest.c, and applications in the contrib directory.
Avoid out-of-bounds memory access in png_user_version_check().
Simplified and future-proofed png_user_version_check().
Fixed GCC unsigned int->float warnings. Various versions of GCC
seem to generate warnings when an unsigned value is implicitly
converted to double. This is probably a GCC bug but this change
avoids the issue by explicitly converting to (int) where safe.
Free all allocated memory in pngimage. The file buffer cache was left
allocated at the end of the program, harmless but it causes memory
leak reports from clang.
Fixed array size calculations to avoid warnings. At various points
in the code the number of elements in an array is calculated using
sizeof. This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant. This adds appropriate, safe, casts to make the
warnings go away.
Version 1.6.15beta06 [November 6, 2014]
Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING
in the manual, example.c, pngtest.c, and applications in the contrib
directory. It was incorrect advice.
Version 1.6.15beta07 [November 7, 2014]
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
needed by png_reciprocal2().
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
png_do_swap().
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
Version 1.6.15beta08 [November 8, 2014]
More housecleaning in *.h
Version 1.6.15rc01 [November 13, 2014]
Version 1.6.15rc02 [November 14, 2014]
The macros passed in the command line to Borland make were ignored if
similarly-named macros were already defined in makefiles. This behavior
is different from POSIX make and other make programs. Surround the
macro definitions with ifndef guards (Cosmin).
Version 1.6.15rc03 [November 16, 2014]
Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
Removed the obsolete $ARCH variable from scripts/makefile.darwin.
Version 1.6.15 [November 20, 2014]
No changes.
Version 1.6.16beta01 [December 14, 2014]
Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that
don't do alignment correctly.
Revised Makefile.am and scripts/symbols.dfn to work with MinGW/MSYS
(Bob Friesenhahn).
Version 1.6.16beta02 [December 15, 2014]
Revised Makefile.am and scripts/*.dfn again to work with MinGW/MSYS;
renamed scripts/*.dfn to scripts/*.c (John Bowler).
Version 1.6.16beta03 [December 21, 2014]
Quiet a "comparison always true" warning in pngstest.c (John Bowler).
Version 1.6.16rc01 [December 21, 2014]
Restored a test on width that was removed from png.c at libpng-1.6.9
(Bug report by Alex Eubanks, CVE-2015-0973).
Version 1.6.16rc02 [December 21, 2014]
Undid the update to pngrutil.c in 1.6.16rc01.
Version 1.6.16rc03 [December 21, 2014]
Fixed an overflow in png_combine_row() with very wide interlaced images
(Bug report and fix by John Bowler, CVE-2014-9495).
Version 1.6.16 [December 22, 2014]
No changes.
Version 1.6.17beta01 [January 29, 2015]
Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
Corrected the width limit calculation in png_check_IHDR().
Removed user limits from pngfix. Also pass NULL pointers to
png_read_row to skip the unnecessary row de-interlace stuff.
Added testing of png_set_packing() to pngvalid.c
Regenerated configure scripts in the *.tar distributions with libtool-2.4.4
Implement previously untested cases of libpng transforms in pngvalid.c
Fixed byte order in 2-byte filler, in png_do_read_filler().
Made the check for out-of-range values in png_set_tRNS() detect
values that are exactly 2^bit_depth, and work on 16-bit platforms.
Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
pngset.c to avoid warnings about dead code.
Added "& 0xff" to many instances of expressions that are typecast
to (png_byte), to avoid Coverity gripes.
Version 1.6.17beta02 [February 7, 2015]
Work around one more Coverity-scan dead-code warning.
Do not build png_product2() when it is unused.
Version 1.6.17beta03 [February 17, 2015]
Display user limits in the output from pngtest.
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
and 1-million-row default limits in pnglibconf.dfa, that can be reset
by the user at build time or run time. This provides a more robust
defense against DOS and as-yet undiscovered overflows.
Version 1.6.17beta04 [February 21, 2015]
Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
Version 1.6.17beta05 [February 25, 2015]
Restored compiling of png_reciprocal2 with PNG_NO_16BIT.
Version 1.6.17beta06 [February 27, 2015]
Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
of png.h.
Avoid runtime checks when converting integer to png_byte with
Visual Studio (Sergey Kosarevsky)
Version 1.6.17rc01 [March 4, 2015]
No changes.
Version 1.6.17rc02 [March 9, 2015]
Removed some comments that the configure script did not handle
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
Free the unknown_chunks structure even when it contains no data.
Version 1.6.17rc03 [March 12, 2015]
Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
for consistency, and remove some useless tests (Alexey Petruchik).
Version 1.6.17rc04 [March 16, 2015]
Remove pnglibconf.h, pnglibconf.c, and pnglibconf.out instead of
pnglibconf.* in "make clean" (Cosmin).
Fix bug in calculation of maxbits, in png_write_sBIT, introduced
in libpng-1.6.17beta01 (John Bowler).
Version 1.6.17rc05 [March 21, 2015]
Define PNG_FILTER_* and PNG_FILTER_VALUE_* in png.h even when WRITE
is not supported (John Bowler). This fixes an error introduced in
libpng-1.6.17beta06.
Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes
the Coverity scan without them.
Version 1.6.17rc06 [March 23, 2015]
Remove pnglibconf.dfn and pnglibconf.pre with "make clean".
Reformatted some "&0xff" instances to "& 0xff".
Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
value was wrong. It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).
Version 1.6.17 [March 26, 2015]
No changes.

XVI. Other sources of information about libpng
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, you can do this:
./configure --enable-maintainer-mode
make maintainer-clean
./autogen.sh --maintainer --clean
./autogen.sh --maintainer
./configure [--prefix=/path] [other options]
make
make install
make check
III. Using scripts/makefile*
Instead, you can use one of the custom-built makefiles in the
"scripts" directory
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
cp scripts/makefile.system makefile
make test
make install
The files that are presently available in the scripts directory
are listed and described in scripts/README.txt.
Or you can use one of the "projects" in the "projects" directory.
Before installing libpng, you must first install zlib, if it
is not already on your system. zlib can usually be found
wherever you got libpng; otherwise go to http://zlib.net. You can place
zlib in in the same directory as libpng or in another directory.
If your system already has a preinstalled zlib you will still need
to have access to the zlib.h and zconf.h include files that
correspond to the version of zlib that's installed.
If you wish to test with a particular zlib that is not first in the
standard library search path, put ZLIBLIB, ZLIBINC, CPPFLAGS, LDFLAGS,
and LD_LIBRARY_PATH in your environment before running "make test"
or "make distcheck":
ZLIBLIB=/path/to/lib export ZLIBLIB
ZLIBINC=/path/to/include export ZLIBINC
CPPFLAGS="-I$ZLIBINC" export CPPFLAGS
LDFLAGS="-L$ZLIBLIB" export LDFLAGS
LD_LIBRARY_PATH="$ZLIBLIB:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH
If you are using one of the makefile scripts, put ZLIBLIB and ZLIBINC
in your environment and type "make ZLIBLIB=$ZLIBLIB ZLIBINC=$ZLIBINC test".
IV. Using cmake
If you want to use "cmake" (see www.cmake.org), type
cmake . -DCMAKE_INSTALL_PREFIX=/path
make
make install
As when using the simple configure method described above, "/path" points to
the installation directory where you want to put the libpng "lib", "include",
and "bin" subdirectories.
V. Directory structure
You can rename the directories that you downloaded (they
might be called "libpng-x.y.z" or "libpngNN" and "zlib-1.2.8"
or "zlib128") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
.. (the parent directory)
libpng (this directory)
INSTALL (this file)
README
*.h, *.c => libpng source files
CMakeLists.txt => "cmake" script
configuration files:
configure.ac, configure, Makefile.am, Makefile.in,
autogen.sh, config.guess, ltmain.sh, missing, libpng.pc.in,
libpng-config.in, aclocal.m4, config.h.in, config.sub,
depcomp, install-sh, mkinstalldirs, test-pngtest.sh
contrib
arm-neon, conftest, examples, gregbook, libtests, pngminim,
pngminus, pngsuite, tools, visupng
projects
cbuilder5, owatcom, visualc71, vstudio, xcode
scripts
makefile.*
*.def (module definition files)
etc.
pngtest.png
etc.
zlib
README, *.h, *.c contrib, etc.
If the line endings in the files look funny, you may wish to get the other
distribution of libpng. It is available in both tar.gz (UNIX style line
endings) and zip (DOS style line endings) formats.
VI. Building with project files
If you are building libpng with MSVC, you can enter the
libpng projects\visualc71 or vstudio directory and follow the instructions
in README.txt.
Otherwise enter the zlib directory and follow the instructions in zlib/README,
then come back here and run "configure" or choose the appropriate
makefile.sys in the scripts directory.
VII. Building with makefiles
Copy the file (or files) that you need from the
scripts directory into this directory, for example
MSDOS example: copy scripts\makefile.msc makefile
copy scripts\pnglibconf.h.prebuilt pnglibconf.h
UNIX example: cp scripts/makefile.std makefile
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
Read the makefile to see if you need to change any source or
target directories to match your preferences.
Then read pnglibconf.dfa to see if you want to make any configuration
changes.
Then just run "make" which will create the libpng library in
this directory and "make test" which will run a quick test that reads
the "pngtest.png" file and writes a "pngout.png" file that should be
identical to it. Look for "9782 zero samples" in the output of the
test. For more confidence, you can run another test by typing
"pngtest pngnow.png" and looking for "289 zero samples" in the output.
Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare
your output with the result shown in contrib/pngsuite/README.
Most of the makefiles will allow you to run "make install" to
put the library in its final resting place (if you want to
do that, run "make install" in the zlib directory first if necessary).
Some also allow you to run "make test-installed" after you have
run "make install".
VIII. Configuring libpng for 16-bit platforms
You will want to look into zconf.h to tell zlib (and thus libpng) that
it cannot allocate more than 64K at a time. Even if you can, the memory
won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
IX. Configuring for DOS
For DOS users who only have access to the lower 640K, you will
have to limit zlib's memory usage via a png_set_compression_mem_level()
call. See zlib.h or zconf.h in the zlib library for more information.
X. Configuring for Medium Model
Libpng's support for medium model has been tested on most of the popular
compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
defined, and FAR gets defined to far in pngconf.h, and you should be
all set. Everything in the library (except for zlib's structure) is
expecting far data. You must use the typedefs with the p or pp on
the end for pointers (or at least look at them and be careful). Make
note that the rows of data are defined as png_bytepp, which is
an "unsigned char far * far *".
XI. Prepending a prefix to exported symbols
Starting with libpng-1.6.0, you can configure libpng (when using the
"configure" script) to prefix all exported symbols by means of the
configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any
string beginning with a letter and containing only uppercase
and lowercase letters, digits, and the underscore (i.e., a C language
identifier). This creates a set of macros in pnglibconf.h, so this is
transparent to applications; their function calls get transformed by
the macros to use the modified names.
XII. Configuring for compiler xxx:
All includes for libpng are in pngconf.h. If you need to add, change
or delete an include, this is the place to do it.
The includes that are not needed outside libpng are placed in pngpriv.h,
which is only used by the routines inside libpng itself.
The files in libpng proper only include pngpriv.h and png.h, which
in turn includes pngconf.h and, as of libpng-1.5.0, pnglibconf.h.
As of libpng-1.5.0, pngpriv.h also includes three other private header
files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material
that previously appeared in the public headers.
XIII. Removing unwanted object code
There are a bunch of #define's in pngconf.h that control what parts of
libpng are compiled. All the defines end in _SUPPORTED. If you are
never going to use a capability, you can change the #define to #undef
before recompiling libpng and save yourself code and data space, or
you can turn off individual capabilities with defines that begin with
PNG_NO_.
In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead.
You can also turn all of the transforms and ancillary chunk capabilities
off en masse with compiler directives that define
PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
or all four, along with directives to turn on any of the capabilities that
you do want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the
extra transformations but still leave the library fully capable of reading
and writing PNG files with all known public chunks. Use of the
PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
that is incapable of reading or writing ancillary chunks. If you are
not using the progressive reading capability, you can turn that off
with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
capability, which you'll still have).
All the reading and writing specific code are in separate files, so the
linker should only grab the files it needs. However, if you want to
make sure, or if you are building a stand alone library, all the
reading files start with "pngr" and all the writing files start with "pngw".
The files that don't match either (like png.c, pngtrans.c, etc.)
are used for both reading and writing, and always need to be included.
The progressive reader is in pngpread.c
If you are creating or distributing a dynamically linked library (a .so
or DLL file), you should not remove or disable any parts of the library,
as this will cause applications linked with different versions of the
library to fail if they call functions not available in your library.
The size of the library itself should not be an issue, because only
those sections that are actually used will be loaded into memory.
XIV. Changes to the build and configuration of libpng in libpng-1.5.x
Details of internal changes to the library code can be found in the CHANGES
file and in the GIT repository logs. These will be of no concern to the vast
majority of library users or builders; however, the few who configure libpng
to a non-default feature set may need to change how this is done.
There should be no need for library builders to alter build scripts if
these use the distributed build support - configure or the makefiles -
however, users of the makefiles may care to update their build scripts
to build pnglibconf.h where the corresponding makefile does not do so.
Building libpng with a non-default configuration has changed completely.
The old method using pngusr.h should still work correctly even though the
way pngusr.h is used in the build has been changed; however, library
builders will probably want to examine the changes to take advantage of
new capabilities and to simplify their build system.
A. Specific changes to library configuration capabilities
The exact mechanism used to control attributes of API functions has
changed. A single set of operating system independent macro definitions
is used and operating system specific directives are defined in
pnglibconf.h
As part of this the mechanism used to choose procedure call standards on
those systems that allow a choice has been changed. At present this only
affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems
running on Intel processors. As before, PNGAPI is defined where required
to control the exported API functions; however, two new macros, PNGCBAPI
and PNGCAPI, are used instead for callback functions (PNGCBAPI) and
(PNGCAPI) for functions that must match a C library prototype (currently
only png_longjmp_ptr, which must match the C longjmp function.) The new
approach is documented in pngconf.h
Despite these changes, libpng 1.5.0 only supports the native C function
calling standard on those platforms tested so far (__cdecl on Microsoft
Windows). This is because the support requirements for alternative
calling conventions seem to no longer exist. Developers who find it
necessary to set PNG_API_RULE to 1 should advise the mailing list
(png-mng-implement) of this and library builders who use Openwatcom and
therefore set PNG_API_RULE to 2 should also contact the mailing list.
B. Changes to the configuration mechanism
Prior to libpng-1.5.0 library builders who needed to configure libpng
had either to modify the exported pngconf.h header file to add system
specific configuration or had to write feature selection macros into
pngusr.h and cause this to be included into pngconf.h by defining
PNG_USER_CONFIG. The latter mechanism had the disadvantage that an
application built without PNG_USER_CONFIG defined would see the
unmodified, default, libpng API and thus would probably fail to link.
These mechanisms still work in the configure build and in any makefile
build that builds pnglibconf.h, although the feature selection macros
have changed somewhat as described above. In 1.5.0, however, pngusr.h is
processed only once, at the time the exported header file pnglibconf.h is
built. pngconf.h no longer includes pngusr.h; therefore, pngusr.h is ignored
after the build of pnglibconf.h and it is never included in an application
build.
The formerly used alternative of adding a list of feature macros to the
CPPFLAGS setting in the build also still works; however, the macros will be
copied to pnglibconf.h and this may produce macro redefinition warnings
when the individual C files are compiled.
All configuration now only works if pnglibconf.h is built from
scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
(the original author of awk) maintains C source code of that awk and this
and all known later implementations (often called by subtly different
names - nawk and gawk for example) are adequate to build pnglibconf.h.
The Sun Microsystems (now Oracle) program 'awk' is an earlier version
and does not work; this may also apply to other systems that have a
functioning awk called 'nawk'.
Configuration options are now documented in scripts/pnglibconf.dfa. This
file also includes dependency information that ensures a configuration is
consistent; that is, if a feature is switched off, dependent features are
also switched off. As a recommended alternative to using feature macros in
pngusr.h a system builder may also define equivalent options in pngusr.dfa
(or, indeed, any file) and add that to the configuration by setting
DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate
how to do this, and also illustrate a case where pngusr.h is still required.
After you have built libpng, the definitions that were recorded in
pnglibconf.h are available to your application (pnglibconf.h is included
in png.h and gets installed alongside png.h and pngconf.h in your
$PREFIX/include directory). Do not edit pnglibconf.h after you have built
libpng, because than the settings would not accurately reflect the settings
that were used to build libpng.
XV. Setjmp/longjmp issues
Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp()
is known to be not thread-safe on some platforms and we don't know of
any platform where it is guaranteed to be thread-safe. Therefore, if
your application is going to be using multiple threads, you should
configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with
-DPNG_NO_SETJMP on your compile line, or with
#undef PNG_SETJMP_SUPPORTED
in your pnglibconf.h or pngusr.h.
Starting with libpng-1.6.0, the library included a "simplified API".
This requires setjmp/longjmp, so you must either build the library
with PNG_SETJMP_SUPPORTED defined, or with PNG_SIMPLIFIED_READ_SUPPORTED
and PNG_SIMPLIFIED_WRITE_SUPPORTED undefined.
XVI. 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.

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

* point APIs, but the floating point API will also accept floating point

/* Compile time options.
* =====================
* In a multi-arch build the compiler may compile the code several times for the
* same object module, producing different binaries for different architectures.
* When this happens configure-time setting of the target host options cannot be
* done and this interferes with the handling of the ARM NEON optimizations, and
* possibly other similar optimizations. Put additional tests here; in general
* this is needed when the same option can be changed at both compile time and
* run time depending on the target OS (i.e. iOS vs Android.)
*
* NOTE: symbol prefixing does not pass $(CFLAGS) to the preprocessor, because
* this is not possible with certain compilers (Oracle SUN OS CC), as a result
* it is necessary to ensure that all extern functions that *might* be used
* regardless of $(CFLAGS) get declared in this file. The test on __ARM_NEON__
* below is one example of this behavior because it is controlled by the
* presence or not of -mfpu=neon on the GCC command line, it is possible to do
* this in $(CC), e.g. "CC=gcc -mfpu=neon", but people who build libpng rarely
* do this.

* with GCC) then the compiler will define __ARM_NEON__ and we can rely
* unconditionally on NEON instructions not crashing, otherwise we must
* disable use of NEON instructions.
*
* NOTE: at present these optimizations depend on 'ALIGNED_MEMORY', so they
* can only be turned on automatically if that is supported too. If
* PNG_ARM_NEON_OPT is set in CPPFLAGS (to >0) then arm/arm_init.c will fail
* to compile with an appropriate #error if ALIGNED_MEMORY has been turned

/* Constants for known chunk types.
*
* MAINTAINERS: If you need to add a chunk, define the name here.
* For historical reasons these constants have the form png_<name>; i.e.
* the prefix is lower case. Please use decimal values as the parameters to
* match the ISO PNG specification and to avoid relying on the C locale
* interpretation of character values. Please keep the list sorted.
*
* Notice that PNG_U32 is used to define a 32-bit value for the 4 byte chunk
* type. In fact the specification does not express chunk types this way,
* however using a 32-bit value means that the chunk type can be read from the
* stream using exactly the same code as used for a 32-bit unsigned value and
* can be examined far more efficiently (using one arithmetic compare).
*
* Prior to 1.5.6 the chunk type constants were expressed as C strings. The
* libpng API still uses strings for 'unknown' chunks and a macro,
* PNG_STRING_FROM_CHUNK, allows a string to be generated if required. Notice
* that for portable code numeric values must still be used; the string "IHDR"
* is not portable and neither is PNG_U32('I', 'H', 'D', 'R').
*
* In 1.7.0 the definitions will be made public in png.h to avoid having to
* duplicate the same definitions in application code.
