I have tested Fanning's 'xplot' routine, which plots a damped sine into
an object graphics window. When I ouput this data to my printer the
resulting image is distorted (indepent of the screen image). How can I
change the properties of my print output to equal length ratio ?
Bad enough, the IDLgrPrinter Object has no DIMENSIONS property !

Humm. I don't think you are using the latest version, because
I recently (several months ago now, I think) added the capability
in all these object graphics programs to produce printer output
that has exactly the same aspect ratio as the plot in the
display window. I just tested the latest XPLOT and it worked
perfectly.
I do this, of course, by obtaining the DIMENSIONS property of
both the display window and the printer. :-)
Perhaps an IDL upgrade should be on your Christmas list.
Cheers,
David
