Hi,
I'm having a problem with color tables in IDL under Windows NT. Windows
is set to display 2^24 colors (16 million). The display settings seem to
be similar to IDL on our Silicon Graphics workstations
(!D.N_COLORS=2^24, !D.TABLE_SIZE=256). When I change the color table
(for example using XLOADCT), the new color table is loaded propperly
(verified using TVLCT,r,g,b,/GET) but images are still displayed in
greyscale. What should I change to overcome this problem? I've tried
this on two machines running WinNT and one running Win98 with the same
result. The IDL version is 5.2.
Thanks a lot!
Jacco
