SUMMARY="JBIG2 image decoder"
DESCRIPTION="jbig2dec is a decoder implementation of the JBIG2 image compression
format. JBIG2 is designed for lossy or lossless encoding of 'bilevel' (1-bit
monochrome) images at moderately high resolution, and in particular scanned
paper documents. In this domain it is very efficient, offering compression
ratios on the order of 100:1."
