ABSTRACT:
In accordance with an embodiment of the present invention, a fax decoding/re-encoding system for transferring fax images between a sending fax machine and a receiving fax machine includes a decoder responsive to an encoded fax image defined by rows of scan lines. The decoder decodes the scan lines of the encoded fax image and generates run-length representation of the encoded fax image. A scanline manipulation device is responsive to the run-length representation for manipulating the same and generating a manipulated fax image without generating a bitmap of the encoded fax image. The fax decoding/re-encoding system further including a re-encoder responsive to said manipulated fax image and adaptive to generate a re-encoded fax image that is substantially the same as the encoded fax image, wherein the fax decoding/re-encoding system avoids the need for a bitmap for generating a re-encoded fax image thereby substantially reducing re-encoding time.
