[vtk-developers] vtkImageToStructuredPoints missing GetOutput function

[David Doria]

The GetOutput function is not overriden in vtkImageToStructuredPoints, so if
you try to do this:

vtkStructuredPoints* structuredPoints = i2sp->GetOutput();

it complains that it can't convert from vtkImageData* to
vtkStructuredPoints*

This is fixed by adding:

vtkStructuredPoints* GetOutput();

to vtkImageToStructuredPoints.h

and

vtkStructuredPoints* vtkImageToStructuredPoints::GetOutput()
{
  return vtkStructuredPoints::SafeDownCast(this->GetOutputDataObject(0));
}

to vtkImageToStructuredPoints.cxx

Any objections?

Thanks,

David
