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.
