I just got the latest version of the NCSA XImage binary off of ftp.ncsa.uiuc.edu. It was apparently compiled under 3.3.1, so it should work with my system. I have two questions for anyone who uses this system: (1) The animate option always dumps core when I try to use a wildcard file specification. Is there some way around this? (2) The palette option allows me to fiddle with the RGB values of the X color table, but does not actually change the colors! Is there some option that I need to employ on the X server to make the color table modifiable? Thanks for any help.... -- John D.

Context diffs are at the end of this article if you feel like recompiling the source. Its a lousy program for an sgi machine since it doesn't exploit any of the more advanced parts of the geometry engine (its adequate for your basic 8 bit X workstation). >(2) The palette option allows me to fiddle with the RGB values of the >X color table, but does not actually change the colors!

Tim Hall's is reasonable for this (ftp from swedishchef.lerc.nasa.gov its called Ctedit). >Thanks for any help.... >-- >John D.

The default window manager used for GL windows and X windows is a non-ICCC window manager. ximage assumes as a default that your are using an ICCC compliant wm. If you are not you need to tell ximage. In your .Xdefaults placing a ximage*installCMap: True will tell ximage to use the old method of installing color maps because your window manager won't.
