Abstract

See full text

When a tile is evicted from the cache, an attempt is made to compress the tile using any compression algorithm. The difference is that the colors of the tile are compressed as they are, but the colors can also be transformed with a color transform (for example, lossless YCoCg), and after that those colors are compressed with the same compression algorithm. Several different color transforms may be tried, and selection of which one to use can be done in several ways.
