<div>I believe I ran into the a similar problem before, I wanted to</div>
<div>save what was currently being rendered to screen to an</div>
<div>image file using vtkWindowToimageFilter. This did not work </div>
<div>with the 3d texture volume mapper, but it did for the rest of the</div>
<div>volume renderers. I had to write some code to extract the pixel data</div>
<div>left in the screen buffer, and this worked ok. Sorry I can't be </div>
<div>more specific, this was about 2 months ago, but I posted a </div>
<div>better explanation of what I did to the mailing list at that point, </div>
<div>it should still be in the archives. Hopefully this can give you </div>
<div>some ideas if the general problems are the same,</div>
