Descriptions:

ASCII: as generated by the X utility bmtoa.  Useful for those
       closely bound to X.

Byrd: for local exchange with Vitria Byrd at UAB.  Very primitive hack.
      Input only. But, see Byrd2TIFF, which may be interesting.

CMRL: for local exchange with Qian from CMRL at UAB.  Primitive hack.
      Input only. 

Img: Paul Raveling's format.  Images at venera.isi.edu.
     Under development.  Note two sub-directories, mapped and rgb, for
     different flavors.  Input only

Proprinter: IBM Proprinters.  A printing hack.  Output only.
 
SunRaster: Sun's proprietary format.

UBC: so called because the images first came from Alain Fournier's group
     at UBC.  Now interpreted as "Universal Byte Code".  Raw y,x,z array
     of bytes.  Very useful format!

UBC2: similar, but accepts 16-bit inputs.  Input only.

UNC: UNC format.

VICAR: JPL format. images from 128.102.18.3.  Based on very limited info.

adage: format used on IKONAS Adage displays. obsolete. Output only.

confocal: for interchange with Jill Gemmill at UAB. Input only.

gif: Compu$erve's proprietary format. Input only.

ps: PostScript.  Output only.

sgi: Requires iristools libraries to build.

smalltalk: Smalltalk format. obsolete.

targa: ATT Targa format. needs to be updated and extended...

tex: for use with TeX image macros.  Output only. obsolete.

tiff: Aldus/Microsoft format. requires Leffler's library.  

urt: Utah Raster Toolkit RLE format. Requires the RLE library
     Try:
            anonymous ftp to cs.utah.edu
                get pub/urt-3.0.tar.Z

wf: Wiebe's Format.  A primitive bitmap.  Probably equivalent to lots
    of 1-bit formats.  obsolete.
