ABSTRACT:
The present invention is a method and apparatus for the efficient processing of binary images represented as a run length encoded data stream. The system employs a CPU and cache or other memory for efficiently scaling or scaling and rotating parsed RLE date. Subsequently, the scaled RLE data can be decoded to produce a scaled image bitmap.
