摘要：A system and method for accepting raster data from a Postscript or equivalentimage data generator, identifying portions of the raster image which contain continuoustone data and linework data, dividing those portions into separate tiles and compressing
the data within each tile by a compression method optimized for the type of image datawithin the tile. The compression algorithms are based upon conventional JPEG or LZWtechniques, but enhanced to more efficiently process image data sets with large amountsof blank data.
