                               IMDISP 7.7

                           ==================

     Version 7.7 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 7.7 is available via anonymous ftp at ames.arc.nasa.gov
[128.102.18.3] in a file called imdisp77.zip in the pub/SPACE/SOFTWARE
subdirectory.  It will also be available through simtel [192.88.110.20] at
PD1:<MSDOS.GRAPHICS>IMDISP77.ZIP.

     IMDISP77.ZIP consists of the following files:

                IMDISP.EXE   - IMDISP program version 7.7
                IMDISP.DOC   - User's Guide for IMDISP 7.7
                PALETTES.ZIP - Color palette collection
                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.

     Any feedback to the IMDISP program is highly appreciates.  Any problems
encountered and suggestions for improvement can be sent to the IMDISP
programmers listed below.
