Abstract:
Systems and methods are provided for reducing data size of at least one bitmap image, wherein the bitmap image comprises a plurality of color blocks, wherein each color block is associated with a distinct color plane. In some embodiments, the bitmap image may be compressed. At least one compressed color block that is contained in a transfer frame may be determined, based on information pertaining to a physical offset between successive color planes when they are rendered on a print medium. Further, at least one compressed color block in the transfer frame may be tagged, if the size of the transfer frame exceeds a threshold, and the resolution of the at least one compressed color block that is tagged may be reduced.
