[Paraview] [ParaView] Problem with saving data from python

[Utkarsh Ayachit]

Ah, the box! The box API needs to cleaned up, I am afriad. Until then,
the following is the way to go.

from paraview.simple import *

w = Wavelet()
UpdatePipeline()
bds = w.GetDataInformation().GetBounds()
c = Clip()
c.ClipType="Box"
c.ClipType.Bounds = bds  #<----- NOTE THIS
c.ClipType.Scale = [0.5, 0.5, 1.0]
SaveData("/tmp/foo.vtu")
