IDL 5.4 has some new keywords for producing a PostScript preview
image: PRE_XSIZE, PRE_YSIZE, PRE_DEPTH. These are suppose to
allow you to create a preview, or thumbnail, image of a particular
size.

I just tried it with a screen snapshot:

snapshot = TVRD(True=1)
Set_Plot, 'PS'
Device, /Encapsulate, /Preview, Pre_XSize=100, Pre_YSize=100, $
Pre_Depth=8, Color=1
TV, snapshot, True=1
Device, /Close_File

IDL went away for 5-6 several seconds while the file was written.
But the resulting file was over 17 MBytes in size!

I think I'm going to stick to the tried and true way of
adding preview images in GhostView. :-(

Cheers,

David
