Abstract
Systems and methods are provided for reducing data size of at least one bitmap image, wherein the bitmap image comprises a plurality of image components, wherein each image component is associated with a distinct color plane. The plurality of color planes may be ranked using a dominance rank, wherein the dominance rank for a color plane is based on data in its associated image component. The data size of the at least one image component may be reduced based on the dominance rank of the color plane associated with the image component.
