JBIG2 encodes bi-level (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
