This directory contains software which can be used to display the GXDR        
images using version 11 of the X Window System.                               
                                                                              
Since the X Window interface is available on many hardware platforms,         
only C-language source code and documentation is provided. To create an       
executable program, it is necessary to compile the "xmgndisp.c" file and      
link it with the X11 library appropriate to the target machine. Since         
xmgndisp uses only the lowest level Xlib subroutine calls, it should be       
possible to install it on many flavors of X11, e.g. OpenWindows, Motif,       
etc. Assuming the GxDR CD-ROM has been mounted on /cdrom, a typical           
installation would go as follows:                                             
                                                                              
    cd /tmp                                                                   
    cp /cdrom/software/unix/xmgndisp.c .                                      
    cc -I/usr/include/X11 -o xmgndisp xmgndisp.c -lX11 -lm                    
    cp xmgndisp /usr/local/bin                                                
    cp /cdrom/software/unix/xmgndisp.man /usr/man/manl/xmgndisp.l             
                                                                              
Xmgndisp will also display the images on Magellan MIDR disks. It can          
translate between pixel address and latitude/longitude for most               
VICAR2 images in SINUSOIDAL, MERCATOR, and polar STEREOGRAPHIC                
projections.  It has been tested on the following platforms:
