[Insight-users] ResampleImageFilter flips origin

[Bill Lorensen]

I think Snap may use VTK as a viewer. A VTK has a flipped y axis
compared to ITK, but I would assume Snap handles that.

Can you "Print" the input and output images of the resample?

The outpupt would be:
resample->Update()
resample->GetOutput()->Prit(std::cout);

Likewise for the input.
