- Libpng 1.5.14 - January 24, 2013
- 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-1.5.14.tar.xz (LZMA-compressed, recommended)
- libpng-1.5.14.tar.gz
- libpng-1.5.14.tar.bz2
- Source files with CRLF line endings (for Windows), without the
- "configure" script
- lpng1514.7z (LZMA-compressed, recommended)
- lpng1514.zip
- Other information:
- libpng-1.5.14-README.txt
- libpng-1.5.14-LICENSE.txt
- Changes since the last public release (1.5.13):
- Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
- Warn about the incorrect runtime library setting for VS2010 debug DLL builds.
- Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
- pngrtran.c (Domani Hannes).
- Check for png_ptr==NULL earlier in png_zalloc().
- Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
- Rearranged building of ARM NEON optimizations. The ARM specific code is
- split out entirely to the arm subdirectory and changes to configure.ac and
- Makefile.am to add new stuff are reduced. Now material code changes,
- although for build test purposes, --enable-arm-neon now builds on non-ARM
- systems.
- Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5.
- Fixed cases of unquoted DESTDIR in Makefile.am
- Fixed a minor bug in types to malloc and major bug in handling compressed
- iTXt. Compressed iTXt could not be handled.
- Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
- Disassembled the version number in scripts/options.awk (necessary for
- building on SunOs).
- Fixed Windows build issues, enabled ARM compilation. Various warnings issued
- by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
- GCCs.) ARM support is enabled by default in zlib.props (unsupported by
- Microsoft) and ARM compilation is made possible by deleting the check for
- x86. The test programs cannot be run because they are not signed.
- Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
- Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h])
- in configure.ac
- De-configured build fixes to make a range of deconfiguration options (such
- as switching off read or write support) work in more cases. Also upgraded
- pngtest and pngvalid to the libpng 1.6 versions (with some modifications)
- which provide more extensive testing. Replaced pngtest.png because pngtest
- writes the ancillary chunks in a different order.
- Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
- (Bug report from yuris).
- Revised test for validity of "num_unknowns" to eliminate compiler warnings.
- Check the validity of the "nentries" parameter of png_set_sPLT() and the
- "num_text" parameter of png_set_text_2().
