Re: [Insight-users] problems using itkVectorResampleImageFilter

[Tomáš Kazmar]

It is kind of silly because there is already Size() and
GetNumberOfElements() that return the same information
and it is called statically from the filter:

  const unsigned int numberOfComponents = PixelType::GetNumberOfComponents();

...but it seems it would make it work:)

# It may be silly, but would it be possible to add a
