ABSTRACT:
A method for decompressing a job in a document management system, such as a printer, scanner or display device, is provided. The method includes buffering the compressed image data, and decompressing the buffered compressed image data such that the decompressing varies as a function of a resolution level and either a first set of quality layers or a second set of quality layers. The number of quality layers in the first quality layer set is greater than the number of quality layers in the second quality set and, pursuant to the decompressing, the resolution level is corresponded with the second quality layer set so that the compressed image data is decompressed with less quality layers than in the first quality layer set.
