Hello,
I have the following macro which creates a ProgrammableSource in
ParaView. I'm wondering why the script seems to be called three
separate times:
script = """
import time
print 'Script was called.',
print time.strftime('%H:%M:%S')+'.%03d'%(time.time()%1.0*1000)
self.GetImageDataOutput().SetDimensions(100,100,1)
# ... do something expensive here ...
"""
script_request_information = """
from paraview import util
util.SetOutputWholeExtent(self, [0, 100, 0, 100, 0, 0])
"""
ps = ProgrammableSource(
OutputDataSetType='vtkImageData',
Script=script,
ScriptRequestInformation=script_request_information)
GetDisplayProperties(ps).Visibility = 1
Render()
It prints out once when I turn on visibility and two more times when I
Render(). How can I keep the script from running more than once?
Thanks!
