Abstract

A method for performing image decompression. The method includes identifying a pixel in an image, wherein the image comprises a plurality of tiles including color data that is displayed by a plurality of pixels, wherein each tile is associated with a base value, a delta value, and a plurality of indices. One or more tiles associated with the pixel are identified. An interpolated base is determined by interpolating decompressed bases of the one or more tiles. An interpolated delta is determined by interpolating deltas of the one or more tiles. An index is determined for the pixel. A color value is determined for the pixel based on the interpolated base, interpolated delta, and the index.
