Libpng 1.2.0rc1 - August 25, 2001 This is a public release of libpng, intended for use in production codes. Changes since the last public release (1.0.12): Enabled PNG_MNG_FEATURES_SUPPORTED and enabled PNG_ASSEMBLER_CODE_SUPPORTED by default. Added runtime selection of MMX features. Added png_set_strip_error_numbers function and related macros. Enabled user memory function by default. Increased png_mng_features flag from png_byte to png_uint_32. Bumped shared-library (so-number) and dll-number to 3. Updated makefile.ibmc, makefile.gcmmx Added some typecasts to eliminate gcc 3.0 warnings. Changed prototypes of png_write_oFFS width and height from png_uint_32 to png_int_32. Updated example.c Revised prototypes for png_debug_malloc and png_debug_free in pngtest.c Revised pnggccrd.c to conditionally compile some thread-unsafe code only when PNG_THREAD_UNSAFE_OK is defined. Added tests to prevent pngwutil.c from writing a bKGD or tRNS chunk with value exceeding 2^bit_depth-1 Removed restriction that do_invert_mono only operate on 1-bit opaque files Replaced calls to fprintf(stderr,...) with png_warning() or png_debug() in pnggccrd.c Fixed contrib/gregbook/rpng-x.c, rpng2-x.c to avoid crash with XFreeGC().
