A method for compressing digital documents with control of image quality and compression rate

摘要: A method and apparatus for compressing decompressing electronic documents, with maximum intradocument independence, flexibility in optimization of compression modes. The includes receiving documents containing unknown combinations a plural data types, including scanned data, computer rendered compressed and/or rendering tags; dividing the received image into strips blocks determining from itself, which types are present each block; type block optimized its type. Scanned may be further segmented where is said step If process include additional functions ratio thereof, accepting use as, or recompressing based on acceptability ration determination. An instruction set generated that allows detailed decompression to combined transmitted data. structure shown, segregates strip processing independence.
