Hi Everybody!
I want to produce a filled contour with IDL as a
postscript file for a HP III Si - Laserprinter.
I have a 100x300 array containing only 0 and 1.
I want the 0 to be plottet white and the 1 black.
On the display it works fine by typing
contour,datavector,/fill
but producing a postscript file do not reproduce
the picture as a hardcopy. The black as the white
parts have the same color (white) being obly
divided by a small black border line. What do I
have to do to get the black-filled picture on
my printer?
Thanks for the help.

I can't be sure what caused the problem-- maybe a device, /color call
would have helped. Anyway, here is a simple example that produces a
contour plot with black and white shading. If using an idea from
this example doesn't help, then I am not quite sure what to try.
set_plot, 'ps'
device, /color
tvlct, [0,255], [0,255], [0,255]
black=0
white=1
contour, dist(20), nlevels=5, c_color=[black,white], /fill, /xs, /ys
device, /close
Hope this helps. :-)
