Image content may be compressed using a plurality of block truncation coding schemes resulting in a plurality of compressed versions of the image content. The plurality of compressed versions may be combined together into a single data structure. Prior to combining the plurality of compressed versions, each compressed version may be further compressed. In one embodiment, a data structure containing a plurality of block truncation encoded format versions of image content may be received. Rendering hardware-compatible block truncation encoded content from the plurality of compressed versions may be determined and provided to rendering hardware. The hardware may then decode the selected one block truncation encoded format for display. In one embodiment, each of the received plurality of block truncation encoded content versions may be further compressed. Before providing the selected version to the hardware for decoding, the further compression may be decompressed. |
