Re: PostScript and pixmap

["Rick Towler" <rtowler(at)u.washington.edu>]

Why do you need to place the pixmap into a PS plot?  Can you just set the
plotting device (using SET_PLOT) to PS and re-plot your data?  If you put
your plotting commands in a subroutine you could easily save it in all sorts
of formats by using SET_PLOT and DEVICE and calling your plotting routine.

If you NEED to do it the hard way, you do something like this:

image = TVRD()
SET_PLOT, 'PS'
DEVICE, filename='plot.ps'
TV, image
DEVICE, /CLOSE

There are a lot of details I left out but this should get you started.


If you are new to PS output with IDL I suggest David Fanning's IDL book.
You might also want to check out Liam Gumley's new book too.  Both are
available thru Amazon.
