There are several groups of students here at the UofA who are just learning
Xview/OpenLook (etc.), and we are doing image processing type work where
we need to be able to set the color map to our own (GreyScale) color map
with *** 256 *** levels, i.e., the WHOLE COLORMAP. We realize that that will
wipe out any other colormaps being used currently by other programs. This is
OK (regrettable, but OK).
We are using SUN SparcStations (with and without the GFX board). We know
how to set the colormap but we can't figure out how to grab the entire
colormap of 256 values so that we can do our GreyScale images.
People have sent us source code to set the colormap but none of it set
the colormap to acquire all of the 256 levels to do with as we please.
Can anyone help us? We really need the whole 256 greyscale levels!!!
Any help would be DEEPLY appreciated as we are getting close to the end of
the semester and need to get our projects and homework finished.
Thanks a whole lot!
