| TODO - list of things to do for libpng: | |
| Final bug fixes. | |
| Better C++ wrapper/full C++ implementation? | |
| Fix problem with C++ and EXTERN "C". | |
| cHRM transformation. | |
| Remove setjmp/longjmp usage in favor of returning error codes. As a start on | |
| this, minimize the use of png_error(), replacing them with | |
| png_warning(); return(0); or similar. | |
| Palette creation. | |
| Add "grayscale->palette" transformation and "palette->grayscale" detection. | |
| Improved dithering. | |
| Multi-lingual error and warning message support. | |
| Complete sRGB transformation (presently it simply uses gamma=0.45455). | |
| Man pages for function calls. | |
| Better documentation. | |
| Better filter selection | |
| (counting huffman bits/precompression? filter inertia? filter costs?). | |
| Histogram creation. | |
| Text conversion between different code pages (Latin-1 -> Mac and DOS). | |
| Avoid building gamma tables whenever possible. | |
| Use greater precision when changing to linear gamma for compositing against | |
| background and doing rgb-to-gray transformation. | |
| Investigate pre-incremented loop counters and other loop constructions. | |
| Add interpolated method of handling interlacing. | |
| Extend pngvalid.c to validate more of the libpng transformations. | |
| Refactor preprocessor conditionals to compile entire statements | |
