[ITK-users] [ITK] Overload GenerateOutputInformation

[Matt McCormick]

Hi Gianna,

Yes, if the Size of the Output Image is different than the Size of the
Input Image, GenerateOutputInformation must be overloaded and that
information imparted there. For more information, see the section of
the ITK Software Guide [1] on creating your own filters.

Please let us know if you have other questions.

Thanks,
Matt
