# The graphics/jbigkit port

## jbigkit-2.0 – lossless image compression library, with lightweight version

## Description

    JBIG-KIT implements a highly effective data compression algorithm for
    bi-level high-resolution images such as fax pages or scanned
    documents.

    JBIG-KIT provides a portable library of compression and decompression
    functions with a documented interface that you can very easily include
    into your image or document processing software. In addition, JBIG-KIT
    provides ready-to-use compression and decompression programs with a
    simple command line interface (similar to the converters found in Jef
    Poskanzer's PBM graphics file conversion package).

    New in version 2.0 is an additional 'lightweight' version of the jbig
    library, named jbig85. This implements only the T.85 profile of the
    the full standard in the ITU-T recommendation, but is far smaller
    and uses much less memory while encoding. See the homepage for more
    details: http://www.cl.cam.ac.uk/~mgk25/jbigkit/

    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/>).
