Changes since the last public release (1.4.0):
|
|
|
|
version 1.4.1 [February 25, 2010]
|
|
|
|
Updated CMakeLists.txt for consistent indentation and to avoid an
|
|
unclosed if-statement warning (Philip Lowman).
|
|
Revised Makefile.am and Makefile.in to remove references to Y2KINFO,
|
|
KNOWNBUG, and libpng.la (Robert Schwebel).
|
|
Revised the makefiles to install the same files and symbolic
|
|
except for libpng.la and libpng14.la.
|
|
Make png_set|get_compression_buffer_size() available even when
|
|
PNG_WRITE_SUPPORTED is not enabled.
|
|
Revised Makefile.am and Makefile.in to simplify their maintenance.
|
|
Revised the makefiles to install a link to libpng14.so.14.1
|
|
Removed png_set_premultiply_alpha() from scripts/*.def
|
|
Revised png_decompress_chunk() to improve speed and memory usage when
|
|
decoding large chunks, using a two-pass method suggested by John Bowler.
|
|
Added png_set|get_chunk_malloc_max() functions.
|
|
Relocated "int k" declaration in pngtest.c to minimize its scope.
|
|
Folded some long lines in the source files.
|
|
Added defineable PNG_USER_CHUNK_CACHE_MAX and PNG_USER_CHUNK_MALLOC_MAX
|
|
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
|
|
png_ptr->png_user_chunk_malloc_max.
|
|
Return allocated "old_buffer" in png_push_save_buffer() before calling
|
|
png_error(), to avoid a potential memory leak.
|
|
Removed the cbuilder5 project, which has not been updated to 1.4.0.
|
|
Complete rewrite of two-pass png_decompress_chunk() by John Bowler.
|
|
Removed obsolete unused MMX-querying support from contrib/gregbook
|
|
Removed the AIX redefinition of jmpbuf in png.h
|
|
Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
|
|
when using AIX compiler.
|
|
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
