Utkarsh.

'Fraid not. This still only returns the same size as the renderwindow, setting the interactive subsample rate to N doesn't make the size smaller.

I'll keep trying. thanks anyway.

Look at  vtkSurfaceLICPainter (Perhaps PrepareForRendering() ). I believe you may be missing using the GetTiledSizeAndOrigin(). I cannot remember the details off the top of my head, but that should give you a starting point.
