[Paraview] Relation between magnitude and camera view angle in SaveScreenshot

[Gregory Zaccaro]

Hi Paraviewers,


I have a simple question regarding the screenshot saving feature within Paraview.


I wrote a python script that I run with pvbatch which basically :

1) Load a polydata

2) Create a render view

3) Set up the camera (position, focal point, view angle)

4) Take a screenshot with SaveScreenshot(file_name, renderView1, quality=100, magnification=magnification)


There is a correlation between the magnification and the allowed View Angle values, but I can't figure out what it is.


The scale changes a lot between 150 deg and 170 deg of View Angle if the magnification =1.
When magnification is superior to 1 (ex. 2), the scales doesn't change much between 150 and 170 deg of View Angle. Why ?


What did I miss to understand the relation between these two parameters ?
