==================
                               IMDISP 7.9
                           ==================

     Version 7.9 of the IMDISP program has now been released.  IMDISP is an
interactive image processing program that runs on an IBM PC computer.  It was
written to be used with the Voyager and Magellan images which are available
on CD-ROM.  IMDISP has appeared on the GRIPS CDROM (version 4.4) and the
GRIPS 2 CDROM (version 5.6), and is currently distributed with the planetary
images CDROMs.

     IMDISP 7.9 is available via anonymous ftp at ames.arc.nasa.gov
[128.102.18.3] in a file called imdisp79.zip in the pub/SPACE/SOFTWARE
subdirectory.

     IMDISP79.ZIP consists of the following files:

                IMDISP.EXE   - IMDISP program version 7.9
                IMDISP.DOC   - User's Guide for IMDISP 7.9
                IMDISP.HLP   - IMDISP Help file
                PALETTES.ZIP - Collection of color palettes
                PAL.BAT      - Batch file to display each color palette
                CYCLE.BAT    - Batch file to color cycle each color palette
                COPIM.EXE    - Image copying program
                CONVERT.EXE  - Pixel conversion program

     The demo files have not changed but have been repackaged into two
files of more manageable sizes, IMDISPD1.ZIP and IMDISPD2.ZIP.  The demo
requires a minimum of a 800x600 graphics display, 3MB of memory, and 3MB of
hard disk space.

     Being one of the programmers for IMDISP, I would appreciate any
feedback on IMDISP, including any problems encountered and suggestions for
improvement.  The features of IMDISP are listed below.
