Options - x and - y can be used to stop the decompression at a specified maximal output image size . The representation created and an associated string dictionary allow decompression at any random access point . The former technique involves the compression of data entering a communications link and its subsequent decompression at the other end . Furthermore , we also present a pattern matching method that allows for retrieving a small pattern in a larger compressed image without performing decompression at all .
