You can now use the CREATE_PS keyword with cgControl
to pass the name of a PostScript file. Using this keyword
will automatically and programmatically cause the cgWindow
app to create a PostScript file of its commands.

IDL> cgPlot, cgDemoData(1), /Window
IDL> cgControl, Create_PS='test.ps'

Get an updated Library, because I found an odd problem in
cgDefCharsize that I still don't understand. I modified
cdDefCharsize recently to use Str_Size to create default
character sizes for the Coyote Graphics routines. This
allows the text to get bigger when the window gets bigger,
and vice versa. But, for reasons I don't fully understand,
using Str_Size in a PostScript context causes an extra
page of PostScript to be produced. For the moment, I've
disabled its use in PostScript, which--as it happens--I
didn't need anyway. So, the problem is fixed, although I
don't completely understand why. :-)

Cheers,

David
