Hello,
I'm developing a colour editor for use with an image display program for
Linux and Sun Solaris. I've found that when I update the colour table for
an RGB image, the image display isn't updated. However, when I run the same
program under Windows 2000, the image IS updated as expected.
I'm running IDL 6.0 set with
Device, Decomposed=0
The display is 24-bit in each case for Windows, Linux and Solaris platforms.
When I alter the colour table I re-display the image using
TV, image, True=3
The image has dimensions (m, n, 3)
As a test, I tried adapting one of Dave Fanning's programs (thank you for
this!), "color_example.pro" to run loading the RGB image. Again, it works
under Windows but not Linux or Solaris.
Has anyone come across anything like this? Any ideas?
With thanks,
Phil
