I have an IDL 5 program that uses polyline objects to draw orbits of
bodies in the solar system. Typically, I have a dozen or so objects,
and each one has 120 vertices. This produces great output on the
screen, but I'm having quite a bit of trouble getting decent printed
copy. I can use IDLgrWindow::Read() and write_jpeg to get mediocre
output, but I'd like to do better. When I use an IDLgrPrinter object
and produce postscript output, the resulting ps file is about 15 megs.
The printers and programs like powerpoint die trying to do anyting
with it. Any ideas?

I got a brand new printer today, having been thinking for
awhile that my printer problems were related to my extremely
reliable, but hopelessly outdated Apple Personal Laserwriter.
This one has 36 MBytes of RAM, and is fast, fast, fast.
Imagine my surprise, then, when I tried to print out a simple
little object graphics program as the first "test case".
I waited for about 5 minutes before windows started to shut
down, my virtual memory was overflowing, and I started getting
cryptic error messages from IDL. I finally had to leave to
go get the kids. I never did get anything out of the damn
printer.
Frankly, I've just about given up on the PRINTER device. :-(
Cheers,
David

I don't know a darn thing about object graphics, but in direct graphics
you could try creating a large pixmap window (say 2000x2000 pixels),
drawing your graphic elements in the pixmap, and saving it as a GIF/JPEG.
Or else you could wait for IDL 5.0.3 (any day now) which might fix the
large Postscript file problem.
Cheers,
Liam.
