Hi All,
We are having problems with image colours when running IDL5.4 through
xterms on Macs. I read an earlier reply that said that it could be due to
bugs in version 0.3 of X11 on Macs.
However, I am having the same problem with my Linux RH9.0 at home. I run
IDL through xterm on Linux and the colour plots to screen are always black
and white. When I print to file (e.g. postscript) the images are colour. I
had RH7.0 last year and this problem did not occur.
Any help would be grateful.
Thanks
Paul.

I tried changing graphics bit size but it did not work. I didn't
think
it would work anyway because I access IDL, which runs on a SunOs,
remotely using RH Linux. Could it be a bug in the X software on RH 9.0? I
did not have this color problem with RH 7.2.
In regards to the Macs has anyone tried changing to an earlier X11
version to see if this fixes the color problem? We can't find the
earlier version. Well actually we didn't try too hard because we want to
know if others have tried first to see if its worth the hassle.
Thanks

This may be a problem with handling 24-bit graphics.
This is what my startup.pro looks like on a RH Linux box:
; Let's deal with the 24-bit display issues.
if (!version.os_family eq 'unix') then device, true_color=24
window, /free, /pixmap, colors=-10
wdelete, !d.window
device, decomposed=0, retain=2, set_character_size=[8,10]
device, get_visual_depth=depth
; Print helpful information at login.
print, ' '
print, 'Display depth: ' + strtrim( depth, 2 )
print, 'Color table size: ' + strtrim( !d.table_size, 2 )
print, ' '
$pwd
$hostname
print, ' '
Try running with that, and see if it helps.
