I am using the 4.3.1 binary version downloaded from the website. I generated my script starting from the trace as you suggest. Uncommenting the ViewSize on your script works. The fact is that it does not work on mine and i really don't understand why. I guess it is related to the settings of the camera.
Have you tried to run my script on your machine? I would expect to have a square image with the data fitted perfectly into it, but as soon as I increase the ViewSize above 855x855, only the horizontal size increases. As you can see from the VTK the source data is 24x24. Thanks On 11 September 2015 at 08:51, Dan Lipsa <dan.li...@kitware.com> wrote: > What version of ParaView do you use?
