This is funny I got colors with your script too, but what is the
difference to my
script
if strlowcase(!version.os) eq 'linux' then device,
get_visual_depth=depth
if strlowcase(!version.os) eq 'linux' then device, true_color=depth
if strlowcase(!version.os) eq 'linux' then window, /free, /pixmap
if strlowcase(!version.os) eq 'linux' then wdelete, !d.window
if strlowcase(!version.os) eq 'linux' then device,bypass_translation=0
if strlowcase(!version.os) eq 'linux' then device, retain=2
if strlowcase(!version.os) eq 'linux' then decomposed=0
delvar,depth
I have added the line at the correct place and this didn't work!
My result is that it is forbidden to ask for the visual_depth!!!
If I exclude this line and set myself depth to 24 all is good, but how
will I determine now between 16bit and 24 bit ?
