Problems with visual depth of 24 in IDL 6.1 [message #56341]

Hello!

My problem, here we are:

I shall apply an IDL Program which produced perfectly good pictures
when using a graphic card of visual depth=16. However, my graphic Card
seems to be younger having a visual depth of 24. The pictures I get
are black, because IDL does not recognise the homemade colortables,
defined within the program. If I use the default colours , I can
produce black and white pictures. It has to be the setting of the
visual depth, because if I change the setting of my graphic card to a
depth of 16, I can reproduce the right graphics.

I tried to set the Visual Depth in IDL with
device, Visual_Depth=24
but IDL w'ont accept.

(Probably I should also mention that the visual name ist TrueColor.)

What can i do?

Regards, Vera
