Hi,  
is there a elegant way from the [CannyEdgeDetector example](https://vtk.org/Wiki/VTK/Examples/Cxx/Images/CannyEdgeDetector) vtkPolyData to vtkImageData? I would like to add the edge result to a  
vtkImageActor, to forces the camera to stay perpendicular to the x-y plane.

The vtkPolyDataToImageStencil seems to me inapproriate.

regards 🙂
