[vtkusers] iterating through vtkImageStencilData

[David Gobbi]

Hi Prathamesh,

You can use the following method of vtkImageStencilData to do the iteration:

  int vtkImageStencilData::GetNextExtent(int &r1, int &r2, int xMin,
            int xMax, int yIdx, int zIdx, int &iter);

The documentation describes what each of the parameters is for.  I
started work on a proper iterator for vtkImageStencilData many, many
years ago but never found time to finish it.

  David
