Abstract

A system and method for scaling raster image data in multiple directions. One embodiment of the present invention comprises obtaining input scan lines containing a raster image and obtaining at least one scalingvalue. The method involves a process for altering the length of the scan lines to produce modified scan lines.The method also involves the generation of a plurality of masks, wherein the masks comprise a number of selected bits, and wherein the number of selected bits is based on the scaling value. The method processes sequences of the modified scan lines with individual masks to produce a plurality of output scan lines. The output scan lines are configured to form a raster image having a modified scale in multiple directions.
