ABSTRACT:
A decoding technique that allows a compressed image to be constructed into a full color page for printing is disclosed. The technique employs a split-level image buffer. The image is divided into small blocks which can be individually compressed and decompressed, allowing the image to be constructed and modified in compressed form. Each small block is examined and labeled as being encoded from one of a plurality of predefined encoding processes. Each block is then decoded in response to the encoding processes in which the block was labeled as being.
