[Paraview] zoom control

[Bryan Hinson]

Hello,

I am using Paraview 3.2.3 on Ubuntu Linux to visualize 3D CFD data for my master's thesis.  I would like to be able to take screenshots of multiple datasets at the exact same viewpoint for comparison purposes.  While I can accomplish this by loading more than one dataset and hiding all but one, taking a screenshot and repeating for the other datasets, this is not really a solution because I will run out of memory before I can load everything I want to capture.  

I am using pvsm files to save the state, which works fine, except that when the state loads, the camera settings are all exactly as I left them, but the view is zoomed way in on the dataset.  I cannot find any way to control the exact amount of zoom so as to take consistent screenshots between pvsm loads.  

I have played with lookmarks some, but they seem to suffer the same zooming issue I just mentioned.  

Aside from changing file and pathnames in the pvsm files to get exact Paraview states for multiple datasets, I have been using the program exclusively interactively.  

Any help would be much appreciated.  

Regards,
Bryan Hinson
