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/>).
