 654 monochrome) images at moderately high resolution, and in particular scanned
 655 paper documents.  In this domain it is very efficient, offering compression

 657
 658 This is a decoder only implementation, and currently is in the alpha

 660 maintaining parity with available encoders, so it is useful for real

 724 ISO/IEC 11544:1993), designed for bi-level (one bit per pixel) images such as
 725 black-and-white scanned documents.  It is widely used in fax products, printer
 726 firmware and drivers, document management systems, and imaging software.
 727
 728 This package provides a static C library of (de)compression functions and some
 729 simple command-line converters similar to those provided by netpbm.
 730
 731 Two JBIG1 variants are available.  One (@file{jbig.c}) implements nearly all
 732 options of the standard but has to keep the full uncompressed image in memory.
 733 The other (@file{jbig85.c}) implements just the ITU-T T.85 profile, with
 734 memory management optimized for embedded and fax applications.  It buffers
 735 only a few lines of the uncompressed image in memory and is able to stream
 736 images of initially unknown height.")
