The answer to this question has eluded me for some time now, and I'm wondering
if some kind IDL guru could point me in the right direction.
I have an 8-bit image (satellite data) which is being displayed on a 24-bit
system. I'm currently using
device, true_color=24, decomposed=0
to do this, since I have the 8-bit image and corresponding r-g-b arrays.
I also have some bitplane data, in another 8-bit 2D array, where each of
the 8 bitplanes correspond to a cloud type. (For example, any pixel containing
cirrus would have a bit set in plane number 5.)
What I would like to do is to display any one of these 8 masks, in its own distinct
color, over the original satellite data. I don't need to see the underlying imagery,
so a solid color would be fine, but I do need the capability of toggling the mask on
and off with reasonable speed (less than a second.)
Is this possible using IDL?
