| Guy Schalnat | 0d58058 | 1995-07-20 02:43:20 -0500 | [diff] [blame] | 3 | |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 4 | Final bug fixes. |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 5 | Better C++ wrapper/full C++ implementation? |
| Glenn Randers-Pehrson | 61c32d9 | 2000-02-04 23:40:16 -0600 | [diff] [blame] | 6 | Fix problem with C++ and EXTERN "C". |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 7 | cHRM transformation. |
| Glenn Randers-Pehrson | b709c4a | 2010-03-08 11:34:41 -0600 | [diff] [blame] | 8 | Remove setjmp/longjmp usage in favor of returning error codes. |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 9 | Add "grayscale->palette" transformation and "palette->grayscale" detection. |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 10 | Improved dithering. |
| 11 | Multi-lingual error and warning message support. |
| 12 | Complete sRGB transformation (presently it simply uses gamma=0.45455). |
| 13 | Man pages for function calls. |
| 14 | Better documentation. |
| 15 | Better filter selection |
| 16 | (counting huffman bits/precompression? filter inertia? filter costs?). |
| Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 17 | Histogram creation. |
| 18 | Text conversion between different code pages (Latin-1 -> Mac and DOS). |
| Glenn Randers-Pehrson | bc7156d | 2009-07-06 09:11:54 -0500 | [diff] [blame] | 19 | Avoid building gamma tables whenever possible. |
| Glenn Randers-Pehrson | f05f803 | 2000-12-23 14:27:39 -0600 | [diff] [blame] | 20 | Use greater precision when changing to linear gamma for compositing against |
| 21 | background and doing rgb-to-gray transformation. |
| 22 | Investigate pre-incremented loop counters and other loop constructions. |
| Glenn Randers-Pehrson | 668af4e | 2009-06-24 06:35:59 -0500 | [diff] [blame] | 23 | Add interpolated method of handling interlacing. |
| Glenn Randers-Pehrson | bc7156d | 2009-07-06 09:11:54 -0500 | [diff] [blame] | 24 | Provide for conditional compilation of 16-bit support (except for the |
| 25 | initial stripping down to 8-bits when reading a 16-bit PNG datastream). |
| 26 | Switch to the simpler zlib (zlib/libpng) license if legally possible. |
