Conditionally compile an "else" statement in png_decompress_chunk(). version 1.4.2rc01 [April 10, 2010] No changes. version 1.4.2rc02 [April 16, 2010] 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. version 1.4.2rc03 [April 24, 2010] Added some "(long)" typecasts to printf calls in png_handle_cHRM(). Relaxed the overly-restrictive permissions of some files. version 1.4.2rc04 [April 28, 2010] 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. version 1.4.2rc05 [April 29, 2010] 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 version 1.4.2rc06 [May 3, 2010] Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c Send comments/corrections/commendations to glennrp at users.sourceforge.net or to png-mng-implement at lists.sf.net (subscription required; visit https://lists.sourceforge.net/lists/listinfo/png-mng-implement).
