    IM Raster Toolkit, by Alan Paeth (awpaeth@watcgl.uwaterloo.ca).
    Provides a portable and efficient format and related toolkit.  The
    format is versatile in supporting pixels of arbitrary channels,
    components, and bit precisions while allowing compression and machine
    byte-order independence.  The kit contains more than 50 tools with
    extensive support of image manipulation, digital halftoning and format
    conversion.  Previously distributed on tape c/o the University of
    Waterloo, an FTP version will appear someday.

    manipulation and reads/writes GIF, xwd, xbm, tiff, rle, xim, and other
    formats.

    xloadimage, by Jim Frost <madd@std.com>.  Reads in images in various
    formats and displays them on an X11 screen.  Available via FTP as

    Khoros, a huge (~100 meg) graphical development environment based on
    X11R4.  Khoros components include a visual programming language, code
    generators for extending the visual language and adding new application
    packages to the system, an interactive user interface editor, an
    interactive image display package, an extensive library of image and
    signal processing routines, and 2D/3D plotting packages.  Available via
    FTP as pprg.unm.edu:pub/khoros/*.

    LaboImage, a SunView-based image processing and analysis package.  It
    includes more than 200 image manipulation, processing and measurement
