PPA description

JBIG2 encodes bitonal (1 bpp) images using a number of clever tricks to get better compression than G4. This encoder can:

* generate JBIG2 files, or fragments for embedding in PDFs,
* generic region encoding,
* perform symbol extraction, classification and text region coding,
* perform refinement coding and,
* compress multipage documents.
