2008-12-24Documenting the dither code a bit more and removing SierraLight's not needed ↵Sven Hesse
height argument svn-id: r35530
2008-12-24Moving the dither code to graphics/Sven Hesse
svn-id: r35526
2008-12-17Added support for caching the palette LUT to a fileSven Hesse
svn-id: r35412
2008-12-16Experimental semi-transparency for fillRect, used in the green/red menu ↵Sven Hesse
areas of Urban Runner svn-id: r35406
2008-12-11Changing the Urban Runner sprite drawer to work more correctly. It does use ↵Sven Hesse
YUV data, but I can use the ditherer there svn-id: r35308
2008-12-11On second thought, an octree only works if the color to look up is in the ↵Sven Hesse
palette. So using a table-based approach to find the nearest color now, using only the upper 6 bits to stop the table from getting too large. It still takes noticeable time to build it. :/ But as a result, the video actually looks okay now... svn-id: r35298
2008-12-09Experimental support for VMD frames encoded in Indeo 3 (Indeo 3 decoder ↵Sven Hesse
closely based on the one in ffmpeg). Since Indeo 3 uses full 24bit colors (in YUV-space), frame data is mapped to the current palette (using an octree, should be the fasted way, methinks) and dithered with the Sierra-2-4A ("Filter Light") error distribution algorithm. svn-id: r35290
