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. Avoid a compiler warning about unused png_ptr in translate_gamma_flags() Revise pngtest.c to skip tests of unsupported features. 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. Updated contrib/pngminus/pnm2png.c (Paul Stewart): Check for EOF Ignore "#" delimited comments </pre> Glenn Randers-Pehrson 2013-05-23T12:29:51 http://comments.gmane.org/gmane.comp.graphics.png.announce/75 <pre>Changes since the last public release (1.6.1): Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling. Fixed incorrect warning of excess deflate data. End condition - the warning would be produced if the end of the deflate stream wasn't read in the last row. The warning is harmless. Corrected the test on user transform changes on read. It was in the png_set of the transform function, but that doesn't matter unless the transform function changes the rowbuf size, and that is only valid if transform_info is called. Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c (Flavio Medeiros). Corrected length written to uncompressed iTXt chunks (Samuli Suominen). Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length written by libpng-1.6.0 and 1.6.1. Disallow storing sRGB information when the sRGB is not supported.

Also allow pngpriv.h to be included for preprocessor definitions only, so it can be used in non-C/C++ files. Back ported from libpng 1.7. Made sRGB check numbers consistent. Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug. Removed cc -E workround, corrected png_get_palette_max API Tested on SUN OS cc 5.9, which demonstrates the tokenization problem previously avoided by using /lib/cpp. Since all .dfn output is now protected in double quotes unless it is to be macro substituted the fix should work everywhere. Enabled parallel tests - back ported from libpng-1.7. scripts/pnglibconf.dfa formatting improvements back ported from libpng17. Fixed a race condition in the creation of the build 'scripts' directory while building with a parallel make.

Development of libpng16 began as a branch from libpng-1.5.7 in December 2011. Changes to Libpng from version 1.5.x to 1.6.x: A "simplified API" has been added (see documentation in png.h and a simple example in contrib/examples/pngtopng.c). The new publicly visible API includes the following: macros: PNG_FORMAT_* PNG_IMAGE_* structures: png_control png_image read functions png_image_begin_read_from_file() png_image_begin_read_from_stdio() png_image_begin_read_from_memory() png_image_finish_read() png_image_free() write functions png_image_write_to_file() png_image_write_to_stdio() Starting with libpng-1.6.0, you can configure libpng to prefix all exported symbols, using the PNG_PREFIX macro.

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.

Removed references to png_zalloc() and png_zfree() from the manual. Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating lone semicolons (patch ported from libpng-1.6.0beta11). Corrected handling of the image array and the row_pointers array in example.c When png_set_filler is used to strip a filler channel during write, the code prior to 1.5 would ignore the case where the output required an alpha channel or when the output was a palettized PNG. In libpng-1.5 the ignorance was lost and libpng proceeded to strip the channel resulting in a bad (potential memory overwrite) failure later. This reverts the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is expected to issue an error on the erroneous png_set_fille</pre> Glenn Randers-Pehrson 2012-09-27T12:02:01 http://comments.gmane.org/gmane.comp.graphics.png.announce/67 <pre>libpng-1.0.60, 1.2.50, 1.4.12, 1.5.12, and 1.6.0beta26 are available from ftp://ftp.simplesystems.org/pub/png/src and from http://libpng.sf.net version 1.0.60 and 1.2.50 [July 9, 2012] Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386. version 1.4.12 [July 10, 2012] Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale), and renamed three whose names were inconsistent with those in pngsuite/README.txt.

Changes since the last public release (1.5.10): Revised scripts/makefile.darwin: use system zlib; remove quotes around architecture list; add missing ppc architecture; add architecture options to shared library link; don't try to create a shared lib based on missing RELEASE variable. Enable png_set_check_for_invalid_index() for both read and write. Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED/#endif in pngpriv.h around declaration of png_handle_unknown().

Revised png_set_text_2() to avoid potential memory corruption (fixes CVE-2011-3048).

Fixed bug with png_handle_hIST with odd chunk length (Frank Busse). Fixed incorrect type (int copy should be png_size_t copy) in png_inflate(). Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic, causing out-of-bounds read in png_set_sCAL() because of failure to copy the string terminators. This bug was introduced in libpng-1.0.6 (Frank Busse). Removed the png_free() of unused png_ptr-&gt;current_text from pngread.c.

The purpose of these releases is to fix the dangerous CVE-2011-3026. The libpng patch is different from the one that was distributed earlier this week by Chromium, in that the libpng user limit feature is not crippled by the patch.

It's not needed and causes trouble for VPATH building. Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper location in configure.ac (Gilles Espinasse).

This would probably have led to a crash. The pngmem.c implementation of png_malloc() included a cast to png_size_t which would fail on large allocations on 16-bit systems. Fix for the preprocessor of the Intel C compiler. The preprocessor splits adjacent &lt; at &gt; signs with a space; this changes the concatentation token from &lt; at &gt;-&lt; at &gt;-&lt; at &gt; to PNG_JOIN; that should work with all compiler preprocessors.

The various interlace mask arrays have been made into arrays of bytes and made PNG_CONST and static (previously some arrays were marked PNG_CONST and some weren't). Additional checks have been added to the transform code to validate the pixel depths after the transforms on both read and write. Removed some redundant code from pngwrite.c, in png_desgtroy_write_struct(). Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4]. This removes the need to allocate temporary strings for chunk names on the stack in the read/write code. Unknown chunk handling still uses the string form because this is exposed in the API.

Updated contrib/pngminus/makefile.std (Samuli Souminen) Revised Makefile.am and Makefile.in to look in the right directory for pnglibconf.h.prebuilt Enabled compilation with g++ compiler. This compiler does not recognize the file extension, so it always compiles with C++ rules. Made minor changes to pngrutil.c to cast results where C++ expects it but C does not.

Also I added some filenames (CMakeLists.txt, projects/xcode, and pnggccrd.c) to the EXTRA_DIST list so "make distcheck" would work properly. I added "make distcheck" to my private build procedure for all versions to help prevent such errors in the future.
