Greetings all,
its been hours since a post about colors, so I
figured I volunteer a post.
I have IDL 5.5 on Redhat Linux 7.2 running KDE
in 24bit color mode.
I cannot get proper colors to show up on screen
(they are fine in postscript files though).
I have tried the conventional wisdom, ensuring I
am in 24 bit mode, setting the decomposed keyword, etc.
But nothing works. I have gone through every keyword
that device will take (true_color=24, direct_color=24,
translation, etc), and toggled all the relevant
sounding ones to no avail (it seems to be in Direct
Color mode no matter what I do, note below where I
set true_color = 24, but it is still in direct color).
Here is sample code, where I get a yellow rectangle over
the whole plot window, and the surface is blue.
Anyone have any ideas of what is going on here?
Cheers,
bob stockwell
; START CODE
DEVICE, true_color=24,decomposed=0
device,get_decomposed = getdecomp,get_graphics_function = getgrapfunc
device,get_visual_name = visname,get_visual_depth = visdepth
device,get_write_mask=writemask
device,translation = trans
print,' Decomposed = ',getdecomp
print,' graphics function = ',getgrapfunc
print,' get_visual_name = ',visname
print,' get_visual_depth = ',visdepth
print,' translation= ',trans
print,' writemask= ',writemask
window,0
image = dist(100)
loadct,13
shade_surf,image,shade=bytscl(image)
end
************************************
Result of running code:
Decomposed = 0
graphics function = 3
get_visual_name = DirectColor
get_visual_depth = 24
(and a freakin blue surface plot in a yello rectangle).
