Hi all,
this is another 8 bit /24 bit related problem which (I suspect) has
to do more with our graphics cards rather than IDL itself.
I put in the attached file the output from Liam's IDL programs
(colorset, colorinfo) and from running XDPYINFO on a SunSparc 5 with a
24bit display.
The problem is that IDL refuses to start in 8bit mode. Looking at
the xdpyinfo output I noticed that there is only ONE visual entry
(TrueColor, 24bit) for the display.
Is this the reason that IDL won't run in 8bit mode? Do I need to get
a different graphics card? Are there any other options?
Thank you for your help,
Angelos
