- 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.
