This is an encoder for JBIG2.
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
It uses the (Apache-ish licensed) Leptonica library: http://leptonica.com/
x86mph is an optimized library with vector, matrix, and vertex helpers (including an own TnL) It also contains memory helpers, and other stuff such as image processing (color inverting, changing bpp) taking advantage of x86's 3DNow!, MMX, and SSE
Do you think the Allegro blenders are too slow? Do you want to do special
effects in 15/16/32-bpp but can't? Then FBlend is for you! FBlend is
a series of super-fast color blenders for Allegro.
FBlend is anywhere from 4 to 13 times faster than Allegro,
