Hi!
I am real beginner in paraview scripting. Up to now, I used the paraview
graphic platform, but since the tasks are getting more complex, I wanted
to use paraview scripting with python.... and failed.
What I want to do:
- Load .vts-data
- Create Contour
- Set Data Range
- Save State/Save Picture
I wrote the following script:
>from paraview.simple import *
>
>reader = OpenDataFile(PATH+'lfff00300000p_QC.vts')
>contourFilter = Contour(reader)
>contourFilter.ContourBy = 'velocity'
>contourFilter.Isosurfaces = [0.0005, 0.001]
>Show(contourFilter)
>ResetCamera()
>WriteImage('picture.png')
>servermanager.SaveState('pythonstate.pvsm')
If I run the script, two errors occur, probably with the same reason.
The writer says:
vtkSMRenderViewProxy (0x1e6da30): Disabling offscreen rendering since
empty image was detected.
When I open the state, there is nothing displayed. in order to see
anything, I do have to press "Apply" for the Contour filter and "Reset"
for the Camera, then everything looks fine.
How can I implement, that these two operations are conducted?
Thanks, Hartwig
