+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.
