Hi,
I'm trying to pass string arrays stored in vtkPolyData sets through the
pipeline, using Python programmable filters.
Below is a sample code :
In a ProgrammableSource1 :
/output=self.GetOutput()/
/
/
/points=vtk.vtkPoints()/
/points.SetNumberOfPoints(1)/
/points.SetPoint(0,0,0,0)/
/
/
/stra=vtk.vtkStringArray()/
/stra.SetName("hop")/
/stra.Allocate(1)/
/stra.InsertNextValue("hop")/
/
/
/output.SetPoints(points)/
/output.GetPointData().AddArray(stra)/
In a directly connected ProgrammableFilter1 :
/
// input=self.GetInput()/
//
/output=self.GetOutput()/
//
/
/
//
/output.SetPoints(input.GetPoints())/
//
/output.GetPointData().CopyStructure(input.GetPointData())/
//
/
/
//
/print input.GetPointData().GetArray("hop")/
The result of the 'print' call at the end is "None", but should not be
in my understanding. If we do the exact same thing with a
vtkDoubleArray, it works.
Any idea on this issue ?
Thanks,
Yves
