<div class="moz-text-html" lang="x-western"> <big>Hi all. I'm part
of a team that's building a large, multi-window GUI; one of the windows contains
the VTK RenderWindow. We implemented a function to save the scene as a PNG,
but there's a problem: if any of the other windows are in the way of the
RenderWindow, they get incorporated into the resulting PNG snapshot! What
I want to do is take a snapshot of ONLY the contents of the RenderWindow,
regardless of whether or not there are other windows in front of the RenderWindow.
Is there a way to do this?</big> </div>
