Abstract: A method and apparatus is provided for block based compression of a texture using hardware supported compression formats. The method comprises dividing a texture into a plurality of blocks, for each block, determining a transform for use with the block to minimize an error metric, encoding at least one characteristic of the transform into a plurality of bits otherwise available to represent reference component values, and compressing the block.
