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

[Gregory J. Ward]

Hi Oskar,

I have not had any other reports of any problems with the latest  
version of ximage in 8-bit mode, but it's difficult to find hardware  
these days that even supports 8-bit color lookups.  There may well be  
a bug, but I can't find it if I can't find hardware on which to  
reproduce the problem.

Maybe you can just continue to use the old binary for ximage, if  
that's working.  I can see no reason why not to -- it isn't as if the  
Radiance picture format has changed in any incompatible way.
