porting from SGIs to Linux?

[Peter Bismuti]

I'd like to port some applications from SGIs which use a Motif/ViewKit
UI to Linux machines running RedHat.
 These applications rely on pseudo-colors.   My first question is: is
there a simple way of doing this?  Is there some last simple function that 
can be applied to the final pixmap that can alter the colors of
ehe drawing?

I don't particularly understand the question. If you are using
pseudo-color to recolorize images dynamically, computers have been
fast enough to do this by simply rewriting the image with the
new colors for a decade or so. (Remote display is going to be
more of an issue, if you need that.)

It can be done of course, but that means rewriting the code.  The hope was 
to port it as-is with as little messing around as necessary, particularly 
because the GUI has to be ripped out and rewritten removing the ViewKit 
code, unless a license can be purchased.
