Now that I can actually see the postscript output I've three more questions.
1. How do I get the picture to be black on white? If I try this trick
a(where(a eq 0B)) = 225B
then any plots that are with the picture disappear since plots are
done in black. This also makes the picture look very different! I've
also tried reloading the color arrays after set_plot,'ps' with and
without giving /COLOR in the call to DEVICE. What's the catch?
2. I would also like to use PLOTS to draw circles and things on the picture.
How can I position them correctly given that the position and size of the
picture is specified in centimeters (or inches) not NORMAL, DATA, or even
DEVICE coordinates?
3. Wouldn't it be nice if TV understood all of the !p variable especially
!p.multi. Has anyone developed or know of a procedure, say PTV, that works
like PLOT (or PLOTS) but draws an image instead of a graph? If you've only
one picture then things go smoothly, but if you what a graph with a picture
next to it or some other combination things get complicated.
I think that I can do what I want in the window, but the conversion to
postsrcipt does not reproduce what's in the window. I've tried using
TVRD but then you have the black-on-white problem again.
Any hints &/or suggestions are welcome.
Thanks, Roger
