[vtkusers] Screenshot of a particular region of a window (inside a vtkImageSlice)

[David Doria]

I know that vtkWindowToImageFilter essentially allows you to take a
screenshot of a RenderWindow. However, I would like to only save the
part of the window that is inside the bounds of a vtkImageSlice. For
example, if I have an ImageSlice displayed and then do something like
draw on it with a tracer, I want to save the result, but not the
"background" of the render window.

Is there anything in place to do this?

Thanks,

David
