[vtkusers] vtkXMLPUnstructuredGridWriter() howto?

I fixed the extent, but still only Test.pvti and Test_0.vti are generated:

You need to insert a streamer into your pipeline.

here is the Python code:

N = 4

drawing = vtkImageCanvasSource2D()
drawing.SetNumberOfScalarComponents(3)
drawing.SetScalarTypeToUnsignedChar()
drawing.SetExtent(0, 50, 0, 50, 0, 0)
drawing.SetDrawColor(255.0, 255.0, 255.0, 255.0)
drawing.DrawCircle(25, 25, 10)

streamer = vtkImageDataStreamer()
streamer.SetInputConnection(drawing.GetOutputPort())

writer = vtkXMLPImageDataWriter()
writer.SetInputConnection(streamer.GetOutputPort())
writer.SetFileName("Test.pvti")
writer.SetNumberOfPieces(N)
writer.SetEndPiece(N-1)
writer.SetStartPiece(0)
writer.Write()
