|
|---|
| [2] | 2 | TODO - list of things to do for libpng:
|
|---|
| 3 |
|
|---|
| 4 | Final bug fixes.
|
|---|
| 5 | Improve API by hiding the png_struct and png_info structs.
|
|---|
| 6 | Finish work on the no-floating-point version (including gamma compensation)
|
|---|
| 7 | Better C++ wrapper/full C++ implementation?
|
|---|
| 8 | Fix problem with C++ and EXTERN "C".
|
|---|
| 9 | cHRM transformation.
|
|---|
| 10 | Improve setjmp/longjmp usage or remove it in favor of returning error codes.
|
|---|
| 11 | Add "grayscale->palette" transformation and "palette->grayscale" detection.
|
|---|
| 12 | Improved dithering.
|
|---|
| 13 | Multi-lingual error and warning message support.
|
|---|
| 14 | Complete sRGB transformation (presently it simply uses gamma=0.45455).
|
|---|
| 15 | Man pages for function calls.
|
|---|
| 16 | Better documentation.
|
|---|
| 17 | Better filter selection
|
|---|
| 18 | (counting huffman bits/precompression? filter inertia? filter costs?).
|
|---|
| 19 | Histogram creation.
|
|---|
| 20 | Text conversion between different code pages (Latin-1 -> Mac and DOS).
|
|---|
| 21 | Build gamma tables using fixed point (and do away with floating point entirely).
|
|---|
| [846] | 22 | Avoid building gamma tables whenever possible.
|
|---|
| [2] | 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.
|
|---|
| [561] | 26 | Add interpolated method of handling interlacing.
|
|---|
| [846] | 27 | Provide for conditional compilation of 16-bit support (except for the
|
|---|
| 28 | initial stripping down to 8-bits when reading a 16-bit PNG datastream).
|
|---|
| 29 | Switch to the simpler zlib (zlib/libpng) license if legally possible.
