I am trying to take a plot that I have created and make it so that the
user can save it in several formats. I was hoping to include Post script
the plot has been put into a pixmap window

You could ignore the whole rest of the world out there, but better keep
JD happy :-)

Oh, man, that little thing with the sizing of the
plot window over in the "PostScript" window is
the *heart* of this program. I wouldn't use it
without that neat little feature! :-)
(Not to mention it took me a LONG time
to figure out how to do that!)
But, the whole feature *is* confined to a
single PLOTWINDOW object, so it would be
easy enough to subclass the draw method,
I suppose, to allow for direct graphics.
But probably not worth it for the 2-3 people
still stuck with 8-bit graphics (Linux users?). :-)
Cheers,
David
P.S. Let's just say I've gone about 6 months now
without saying DEVICE, DECOMPOSED=0, which I took
to mean we had finally gotten the whole world
over into the 24-bit graphics world. I should have
known better.

So, given this difficulty, is Object Graphics really necessary in
PSConfig? It seems to draw some boxes, etc., but nothing requiring OG
(as far as my limited knowledge of the latter allows me to infer). Is
there a version laying around using DG?

Yes, for people still on the dark side, it is
a problem. There is no practical way to combine
direct graphics and object graphics in the same
program on an 8-bit display. The two graphics
systems just use colors in completely different
ways, which (by definition) will cause havoc
with the one physical color table.
Cheers,
David
