IGES - Initial Graphics Exchange Specification
         Type: 
    Extension:
      Version: 
  Compression:
  Color Depth:
   Maintainer: 
Specification: IGES is a set of protocols for the transfer and display of graphical
               information on remote devices via a telephone or computer communications
               network. IGES does not define any new graphical file formats, but instead
               uses existing formats (such as CGM) to encapsulate graphical data.

               IGES is associated with the NCGA (National Computer Graphics Association) and
               is part of the U.S. Product Data Association (USPRO) and the IGES/PDES
               Organization (IGO). The NCGA administers the National IGES User Group (NIUG),
               which provides access to information on IGES.

JBIG - Joint Bilevel Image Group
         Type: Compression Method
    Extension: Not specified by specification
      Version: 
  Compression: JBIG
  Color Depth: 1-bit (see text)
   Maintainer: ISO, IEC and ITU
Specification: JBIG is a lossless method for compressing black and white (1-bit) raster
               image data. Its primary benefit is as a method for transmitting bi-level
               image data across a communications channel. JBIG's progressive encoding
               scheme allows lower resolution  version of  the image  to be sent first,
               followed by higher resolution  images which build  on the  previously
               transmitted  data (e.g.  75, 150, 300, 450, and 600 DPI). This  capability 
               makes JBIG ideal for replacing less-efficient document imaging transmissions
               methods, such as CCITT Group 3 & 4, but thus far JBIG has not been 
               marketed in such a way as to make this possible.

  Compression: None
  Color Depth: full spectral colors (i.e., infinite)
   Maintainer: Greg Ward <GJWard@lbl.gov>
Specification: http://radsite.lbl.gov/mgf/HOME.html

               MGF is an ASCII-based 3D rendering format designed to model surface geometry
               and materials for the purpose of visible-light simulation and rendering. The
               overall objective of this format is to provide a very simple yet fairly
               complete modeling language that does not place unreasonable demands on the
               applications programmer or the object library creator.

               The format specification is available bundled with an MGF file reader
               and is distributed in the file mgflib0.7.tar.Z on the following sites:
