| Changes since the last public release (1.4.1): |
| Restored the macro definition of png_check_sig(). |
| Conditionally compile an "else" statement in png_decompress_chunk(). |
| Documented the fact that png_set_dither() was disabled since libpng-1.4.0. |
| Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect |
| more accurately what it actually does. At the same time, renamed |
| the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to |
| PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS. |
| Added some "(long)" typecasts to printf calls in png_handle_cHRM(). |
| Relaxed the overly-restrictive permissions of some files. |
| Added the "vstudio" project to replace "visualc6" and "visualc71" which |
| will be removed from libpng-1.5.0. |
| Demonstrate in example.c that lang_key should be initialized. |
| Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in |
| contrib/pngminim/decoder/pngusr.h to make a smaller decoder application. |
| Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined. |
| Removed dummy_inflate.c and uncompr.c from contrib/pngminim/encoder |
| Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED |
| in gregbook/readpng2.c |
| Corrected protection of png_get_user_transform_ptr. The API declaration in |
| png.h is removed if both READ and WRITE USER_TRANSFORM are turned off |
| but was left defined in pngtrans.c |
| Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c |
