Update to 1.6.3: Changes since the last public release (1.6.2): 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. Test for 'arm' not just 'arm' in the host_cpu configure variable. Rebuilt the configure scripts. 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). 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. Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and WRITE_PACK supported (writes error message that it can't read P1 or 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 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. Revised libpng.3 so that "doclifter" can process it. 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. 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. 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. 2013-07-18 08:26:51 +02:00			$NetBSD: distinfo,v 1.105 2013/07/18 06:26:51 wiz Exp $

Update to 1.5.14: Changes since the last public release (1.5.13): Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7 Warn about the incorrect runtime library setting for VS2010 debug DLL builds. Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in pngrtran.c (Domani Hannes). Check for png_ptr==NULL earlier in png_zalloc(). Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS(). Rearranged building of ARM NEON optimizations. The ARM specific code is split out entirely to the arm subdirectory and changes to configure.acand Makefile.am to add new stuff are reduced. Now material code changes, although for build test purposes, --enable-arm-neon now builds on non-ARM systems. Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5. Fixed cases of unquoted DESTDIR in Makefile.am Fixed a minor bug in types to malloc and major bug in handling compressed iTXt. Compressed iTXt could not be handled. Cleaned up whitespace in the synopsis portion of the manpage "libpng.3" Disassembled the version number in scripts/options.awk (necessary for building on SunOs). Fixed Windows build issues, enabled ARM compilation. Various warnings issued by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old GCCs.) ARM support is enabled by default in zlib.props (unsupported by Microsoft) and ARM compilation is made possible by deleting the check for x86. The test programs cannot be run because they are not signed. Fixed 'make distcheck' on SUN OS - libpng.so was not being removed Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h]) in configure.ac De-configured build fixes to make a range of deconfiguration options (such as switching off read or write support) work in more cases. Also upgraded pngtest and pngvalid to the libpng 1.6 versions (with some modifications) which provide more extensive testing. Replaced pngtest.png because pngtest writes the ancillary chunks in a different order. Check validity of "num_unknowns" parameter of png_set_unknown_chunks() (Bug report from yuris). Check the validity of the "nentries" parameter of png_set_sPLT() and the "num_text" parameter of png_set_text_2(). 2013-01-24 09:15:50 +01:00			`SHA1 (patch-aa) = 080c890ee48923db959fcdeeb12e4a5a27845138`
