Is my radeon 9800pro a 8-bit card? //cry
I guess I will be the last person to understand how color works in IDL.:(
In general, I want something like this,
;**********************
pro myLOADCT, ct
ct=fix(ct) mod 41
bottom=ct*256
ncolors=256
new_LOADCT, ct, bottom=bottom, ncolors=ncolors
end
;***********************
;***********************
pro myTV, data, CT=ct
new_TV, data+256*ct
end
;***********************
;***********************
pro mainpro
...
for i=0,40 do myLOADCT, i
...
wset, draw_0
myTV, bytscl(data_1), CT=ct_1
...
wset, draw_2
myTV, bytscl(data_2), CT=ct_2
...
wset, draw_n
myTV, bytscl(data_n), CT=ct_n
...
end
;***********************
Please HELP if any of you understand what I'm trying to do. Thanks for reading.

Uh, get a 24-bit graphics display card? Then you can
have as many color tables working simultaneously as you
like.
