| The Android Open Source Project | 893912b | 2009-03-03 19:30:05 -0800 | [diff] [blame] | 2 | TODO - list of things to do for libpng: |
| 3 | |
| 4 | Final bug fixes. |
| The Android Open Source Project | 893912b | 2009-03-03 19:30:05 -0800 | [diff] [blame] | 5 | Better C++ wrapper/full C++ implementation? |
| 6 | Fix problem with C++ and EXTERN "C". |
| 7 | cHRM transformation. |
| Alex Naidis | 7a055fd | 2016-10-01 12:23:07 +0200 | [diff] [blame] | 8 | Remove setjmp/longjmp usage in favor of returning error codes. As a start on |
| 9 | this, minimize the use of png_error(), replacing them with |
| Leon Scroggins III | 3cc83ac | 2017-10-06 11:02:56 -0400 | [diff] [blame] | 10 | png_warning(); return(0); or similar. |
| Matt Sarett | 9b1fe63 | 2015-11-25 10:21:17 -0500 | [diff] [blame] | 11 | Palette creation. |
| The Android Open Source Project | 893912b | 2009-03-03 19:30:05 -0800 | [diff] [blame] | 12 | Add "grayscale->palette" transformation and "palette->grayscale" detection. |
| 13 | Improved dithering. |
| 14 | Multi-lingual error and warning message support. |
| 15 | Complete sRGB transformation (presently it simply uses gamma=0.45455). |
| 16 | Man pages for function calls. |
| 17 | Better documentation. |
| 18 | Better filter selection |
| 19 | (counting huffman bits/precompression? filter inertia? filter costs?). |
| 20 | Histogram creation. |
| 21 | Text conversion between different code pages (Latin-1 -> Mac and DOS). |
| Chris Craik | b50c217 | 2013-07-29 15:28:30 -0700 | [diff] [blame] | 22 | Avoid building gamma tables whenever possible. |
| The Android Open Source Project | 893912b | 2009-03-03 19:30:05 -0800 | [diff] [blame] | 23 | Use greater precision when changing to linear gamma for compositing against |
| 24 | background and doing rgb-to-gray transformation. |
| 25 | Investigate pre-incremented loop counters and other loop constructions. |
| Patrick Scott | a0bb96c | 2009-07-22 11:50:02 -0400 | [diff] [blame] | 26 | Add interpolated method of handling interlacing. |
| Chris Craik | b50c217 | 2013-07-29 15:28:30 -0700 | [diff] [blame] | 27 | Extend pngvalid.c to validate more of the libpng transformations. |
| Leon Scroggins III | 3cc83ac | 2017-10-06 11:02:56 -0400 | [diff] [blame] | 28 | Refactor preprocessor conditionals to compile entire statements |
