<big>Ok, the first message didn't seem to get through to the mailing
list, so I'll try this again :-)<br>

Hi Charles, thanx for the quick reply! :-)<br>
<br>
Yes, I tried offscreen rendering, but it didn't seem to make any difference
at all. Do I need to enable this "MESA" thing before offscreen rendering will
work?</big><br>

<pre wrap="">Hey Jared,
Have you tried using offscreen rendering? Something like this:
this->renWin->SetOffScreenRendering(1);
... take a snapshot of the render window here
this->renWin->SetOffScreenRendering(0);
I use this to output a series of snapshots (to later create an
animation) and it seems to work fine for me, although I do not have
multiple windows that overlap each other.
Hope this helps,
Charles

<pre wrap=""><!----> 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?
