     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 a test version and is being released for evaluation.    
                                                                              
     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 is also available through simtel [192.88.110.20] at         
PD1:<MSDOS.GRAPHICS>IMDISP77.ZIP.                                             
                                                                              
     IMDISP77.ZIP consists of the following files:

     Also included in a separate file, IMDISPD.ZIP, which is a collection of  
images and batch files which are used to perform a demo for IMDISP.  This demo
is similiar to the one given during the JPL Expo on August 3-4, 1991. The demo
requires a minimum of a 800x600 graphics display and 2MB of memory.           
                                                                              
     Since we are the programmers for IMDISP, we would appreciate any feedback
on IMDISP, including any problems encountered and suggestions for improvement.
