Hi there. I do enjoy paraview simple to automatize some post-processing.  
When i make a screenshot or save animation of a renderview with the following line :  
SaveAnimation(’/tmp/test.png’, renderView1, ImageResolution=[1222, 627], FrameWindow=[0, len(frames)])

a GUI windows is appearing while the animation or screenshot is generated.

Is there a way to ovoid this ?  
Thanks by advance.

You want to use offscreen rendering.

`--use-offscreen-rendering`
