Libpng 1.0.1a April 21, 1998
|
|
|
|
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.
|
|
|
|
Changes since the last release:
|
|
|
|
Optimized Paeth calculations by replacing abs() function calls with intrinsics
|
|
plus other loop optimizations. Improves avg decoding speed by about 20 percent.
|
|
Commented out i386istic "align" compiler flags in makefile.lnx.
|
|
Reduced the default warning level in some makefiles, to make them consistent.
|
|
Removed references to IJG and JPEG in the ansi2knr.c copyright statement.
|
|
Fixed a bug in png_do_strip_filler with XXRRGGBB => RRGGBB transformation.
|
|
Added grayscale and 16-bit capability to png_do_read_filler().
|
|
Fixed a bug in pngset.c, introduced in version 0.99c, that sets rowbytes
|
|
too large when writing an image with bit_depth < 8 (Bob Dellaca).
|
|
Corrected some bugs in the experimental weighted filtering heuristics.
|
|
Moved a misplaced pngrutil code block that truncates tRNS if it has more
|
|
than num_palette entries -- test was done before num_palette was defined.
|
|
Fixed a png_convert_to_rfc1123() bug that converts day 31 to 0 (Steve Eddins).
