ABSTRACT:
A fast, raster-based, enhanced, data compression technique for the printing of compound documents, including pre-processing images in an original page description form of the data before the page data is rasterized, greatly improving compressibility. Unscaled image data is filtered before it is rasterized to the final printing resolution. The filtering specifically enables a separate, near loss-less, compression algorithm to operate on a rasterized page description with high compression ratios. A data compression technique enables a system to compress compound document using a relatively fast and simple algorithm with near loss-less print quality.
