[Paraview] Screenshot sizes on pvbatch

[Magician]

Mirko and Gena,


Thanks for your reply.

I tried both advices.
I couldn't access vtkRenderLargeImage from pvbatch,
but the 'Magnification' option takes good results!

I always export large screenshots because of resizing
(for pseudo-antialiasing), so this technique is very nice for me.
