Abstract
Systems and methods are provided for reducing data size of at least one bitmap image comprising at least one block, wherein the block comprises a plurality of image components, each image component being associated with a distinct color plane. The method may include compressing the plurality of image components of the at least one block. The method may further include ranking the plurality of image components using a dominance rank, wherein the dominance rank for an image component is based on a compression ratio for the image component. The method may also include reducing the resolution of at least one image component associated with the block, based on the dominance rank of the color plane associated with the image component.
