Hi, is it possible for me to draw a 24-bits color filled contour plot on a
24-bits screen or PS file? It is usually a 8-bits contour or grey contour.
Thanks. Tom

Yeah, but I don't think you do that in a PostScript
file, as Tom was asking about. :-)
Cheers,
David

Tom,
I use the hexadecimal format for colors in the contour functions simply
because it is easier for my brain to put a decent color together in
'r-g-b' format under 24-bit colors.
The colors in this call will be
purple 'ff00ff'xl
blue 'ff0000'xl
green '00ff00'xl
red '0000ff'xl

contour,image_array(*,*,image_info.counter), $
xrange = [0,cont_max],yrange = [0,cont_max],xstyle =5,ystyle=5,$
levels = [cont1_val,cont2_val,cont3_val,cont4_val],$
c_colors = ['ff00ff'xl,'ff0000'xl,'00ff00'xl,'0000ff'xl],$
pos = [0,0,611,611],noerase=cont_noerase
