Convert float colors to unsigned char colors
The Transform filter converts any colors to floats, which Paraview cannot handle. To convert them back, you can use this: <source lang="python"> inp = self.GetInput() out = self.GetOutput()
numCells = inp.GetNumberOfCells() data = inp.GetCellData().GetArray("Colors")
newData = vtk.vtkUnsignedCharArray() newData.SetName('Colors_converted') newData.SetNumberOfComponents(3) for i in range(0, 3*numCells):
val = int(data.GetValue(i)) newData.InsertNextValue(val)
out.GetCellData().AddArray(newData) </source>
