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 can be very efficient, offering compression ratios on the order of 100:1. This is a decoder only implementation, and its primary use is in Ghostscript and MuPDF for decoding JBIG2 streams in PDF files. Thus its primary focus is the set of JBIG2 features supported in PDF.
