Libpng 1.7.0beta23 - November 17, 2013
Libpng 1.7.0beta23 - November 18, 2013
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
@ -418,8 +418,12 @@ Version 1.7.0beta22 [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 1.7.0beta23 [November 17, 2013]
Added #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED/#endif in pngpread.c
Version 1.7.0beta23 [November 18, 2013]
Changed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpread.c to
#ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED to be consistent with
what is in pngpriv.h.
Moved prototype for png_handle_unknown() in pngpriv.h outside of
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
