JBIG-KIT implements a highly effective data compression algorithm for
bi-level high-resolution images such as fax pages or scanned documents.
This is a portable library of compression and decompression functions
with a documented interface that can be included into your image or
document processing software. Also provided are ready-to-use compression
and decompression programs with a simple command line interface (similar
to the converters found in Jef Poskanzer's PBM conversion package).
JBIG-KIT implements the specification
International Standard ISO/IEC 11544:1993 and ITU-T Recommendation
T.82(1993), "Information technology - Coded representation of picture
and audio information - progressive bi-level image compression",
<http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>,
which is commonly referred to as the "JBIG standard". JBIG (Joint
Bi-level Image experts Group) is the committee which developed this
international standard for the lossless compression of images using
arithmetic coding. Like the well-known compression algorithms JPEG and
MPEG, also JBIG has been developed and published by the International
Organization for Standardization (ISO) and the International
Telecommunication Union (ITU) (see also <http://www.iso.ch/> and
<http://www.itu.ch/>).
