[Paraview] pvpython: assigning a 2D texture image to an object that has TCords

[Grothausmann, Roman Dr.]

Dear mailing list members,


Is it possible to assign a 2D texture image to an object that has TCords in python?
I found quite a few people trying and reporting that it does not work nor does 
the Trace Option under paraview tell what happens if a texture is assigned in 
the GUI:
http://www.paraview.org/pipermail/paraview/2012-March/024255.html
http://www.paraview.org/Bug/view.php?id=12953

I've tried:

     import paraview.simple as pvs


     reader = pvs.OpenDataFile("test.png)
     #reader.UpdatePipelineInformation()
     reader.UpdatePipeline()
     print reader.GetDataInformation().GetBounds() # needs UpdatePipeline

     obj = pvs.Plane()
     plane1Display = pvs.Show(obj)
     plane1Display.Texture = reader

     dp = pvs.GetDisplayProperties(obj)
     dp.Representation = 'Surface With Edges'

     dp.Texture = reader


but neither plane1Display.Texture nor dp.Texture seem to allow to set the 
texture (see error below)

Any help or hints are very much appreciated
Roman
