Hi,

I have a simple problem that has been bugging me for a week and I
appreciate it if anyone out there could help me. (From my question it
should be obvious that I am not an experienced X programmer!)

I have a gray scale image (256 level) and all I want to do is to open
a window on my color display workstation (it has 8 color planes) with
that image. I don't know whether I need to define a new colormap or
just changing the visual will do the job. I wrote a program that will
open a window with a bitmap image so my problem is to go from 2 levels
to 256 levels)

I appreciate it if you let me know how I can do this or even better
send me sample code (if you already have one) for bringing up a gray-scale
image on a color display.

Thanks again,

Masoud Majidi(majidi@yoko.rutgers.edu)
