[Insight-users] Type problem with ImportImageFilter and GradientAnisotropicDiffusionImageFilter

[Bill Lorensen]

Looks like a typo in FiniteDifferenceImageFilter::CopyInputToOutput.

Change the declaration of the second ImageIterator to:
ImageRegionIterator<TOutputImage> out ...

We'll update the repository and thanks for the bug report,

Bill
