[Radiance-general] [Help] Problem with ximage in 7.3.2

[Gregory J. Ward]

Hi Oskar,

I'm moving this to the Radiance development list, since it is a code  
issue that's of limited use to others.  Please respond there rather  
than replying to this.  (You will need to subscribe first if you

Definitely run both versions of ximage on both machines after  
compiling with -DDEBUG, because the visual selection code changed  
considerably between 3.1.11 and 3.7.2.  It seems the color table code  
also changed, though, and the problem might be there.
