jbig2dec is a decoder library and example utility implementing the JBIG2 bi-level image compression spec. Also known as ITU T.88 and ISO IEC 14492, and included by reference in Adobe's PDF version 1.4 and later. The basic invocation is: jbig2dec [-o <output file>] file.jbig2 It also supports separate 'global' and 'page' streams, generally extracted from some embedded format: jbig2dec [-o <output file>] <global_stream> <page_stream> The program is only partially functional at this time, but should be useful in some limited contexts. We welcome files that the decoder can't handle, or renders incorrectly.
