Maybe I should have better elucidated what I want to do. I'm displaying
an image with overlaid annotation and ROIs. When I display this to a draw
widget, obviously anything that lays outside the window is not drawn. I
want this to extend to when I display on a postscript page, so that parts
of the image/ROI/annotation that lay outside a given area are not drawn.
For PLOTS and XYOUTS, you can specify a clipping window using the CLIP
keyword, so that graphics outside this window are not drawn. I was
wondering if there was a simple way to do this for images as well, because
(at least in IDL 5.4) the CLIP keyword does not apply to the TV procedure.
