PACKAGE DESCRIPTION:
jbigkit: jbigkit (highly effective lossless compression algorithm)
jbigkit:
jbigkit: JBIG is a highly effective lossless compression algorithm for
jbigkit: high-resolution bi-level images (one bit per pixel), which is
jbigkit: particularly suitable for scanned documents or fax pages.
jbigkit:
jbigkit: JBIG-KIT provides a portable library of compression and decompression
jbigkit: functions with a documented interface that you can easily include
jbigkit: into your image or document processing software. JBIG-KIT also
jbigkit: provides ready-to-use compression and decompression programs with a
jbigkit: simple command line interface.
