[Insight-users] Usage of WarpVectorImageFilter

[Karthik Krishnan]

Hi Greg:

itk::WarpVectorImageFilter is meant for use with input images of the type

   Image< Vector< T, D >, N >

rather than
   VectorImage< T, N >

Its looking for the trait Dimension in the pixel type of the image, which
exists only for pixels of the type Vector< T, D > etc.

We could make it work with itk::VectorImage also quite easily, but haven't
done that yet.

Thanks
