[vtkusers] Closed vtkPolyLine to binary image

Mon Jul 12 05:11:02 EDT 2010

Hi,

I added a small example:

http://www.cmake.org/Wiki/VTK/Examples/PolyData/PolyDataContourToImageData

Hope that helps you.

However, please read the NOTE in the description. Maybe you could fix / verify the image origin problem.

regards,
lars
