Hi John,

Is it view.ViewSize you are looking for?
http://www.paraview.org/Wiki/ParaView/Python_Scripting#Take_a_Screenshot_of_a_VTP_File
That is in my "outside paraview" area, which means I've only tried it from a
terminal, running the script with
pvpython ./script.py

I'm not sure if it will work inside python, but let me know if it does / if
that's what you needed.


Thanks,
Dave
