| 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). |
