1*a67afe4dSAndroid Build Coastguard WorkerTODO - list of things to do for libpng:
2*a67afe4dSAndroid Build Coastguard Worker
3*a67afe4dSAndroid Build Coastguard Worker* Fix all defects (duh!)
4*a67afe4dSAndroid Build Coastguard Worker* Better C++ wrapper / full C++ implementation (?)
5*a67afe4dSAndroid Build Coastguard Worker* Fix the problems with C++ and 'extern "C"'.
6*a67afe4dSAndroid Build Coastguard Worker* cHRM transformation.
7*a67afe4dSAndroid Build Coastguard Worker* Palette creation.
8*a67afe4dSAndroid Build Coastguard Worker* "grayscale->palette" transformation and "palette->grayscale" detection.
9*a67afe4dSAndroid Build Coastguard Worker* Improved dithering.
10*a67afe4dSAndroid Build Coastguard Worker* Multi-lingual error and warning message support.
11*a67afe4dSAndroid Build Coastguard Worker* Complete sRGB transformation.  (Currently it simply uses gamma=0.45455.)
12*a67afe4dSAndroid Build Coastguard Worker* Man pages for function calls.
13*a67afe4dSAndroid Build Coastguard Worker* Better documentation.
14*a67afe4dSAndroid Build Coastguard Worker* Better filter selection
15*a67afe4dSAndroid Build Coastguard Worker  (e.g., counting huffman bits/precompression; filter inertia; filter costs).
16*a67afe4dSAndroid Build Coastguard Worker* Histogram creation.
17*a67afe4dSAndroid Build Coastguard Worker* Text conversion between different code pages (e.g., Latin-1 -> Mac).
18*a67afe4dSAndroid Build Coastguard Worker* Avoid building gamma tables whenever possible.
19*a67afe4dSAndroid Build Coastguard Worker* Greater precision in changing to linear gamma for compositing against
20*a67afe4dSAndroid Build Coastguard Worker  background, and in doing rgb-to-gray transformations.
21*a67afe4dSAndroid Build Coastguard Worker* Investigate pre-incremented loop counters and other loop constructions.
22*a67afe4dSAndroid Build Coastguard Worker* Interpolated method of handling interlacing.
23*a67afe4dSAndroid Build Coastguard Worker* More validations for libpng transformations.
