[Paraview] pvpython script to create a screen shot of a PVSM

[Grothausmann, Roman Dr.]

Dear mailing list members,


I'm trying to write a simple pvpython script that merely takes a screen shot of 
a loaded PVSM:
https://github.com/romangrothausmann/ParaView_scripts/blob/master/render-view.py

However, even if a voxel dataset is displayed as a volume when loaded in PV GUI, 
it does not get rendered by the script.
I've tried to explicitly set the rendering style to Volume and assigned a 
OpacityTransferFunction (as told here: 
http://www.paraview.org/pipermail/paraview/2013-November/029918.html)
Furthermore, the camera position stored in the PVSM does not seem to get loaded, 
nor whether an object is hidden.
What else do I need to do in the script to get PV GUI behaviour?

Also, what to do about this warning:
vtkSMProxyIterator (0x61ef820): ProxyManager is not set. Can not perform 
operation: Begin()


Any help or hints are very much appreciated
Roman
