[Insight-users] Compilation error: itkVectorResampleImageFilter.txx:169: error: ‘GetNumberOfComponents’ is not a member of ‘itk::FixedArray<double, 3u>’

[Andreas Schuh]

Hi Ricardo,

As the error message states, the type used as PixelType has to provide the static member GetNumberOfComponents() as the itk::VectorResampleImageFilter calls this method in order to determine the number of vector components. Thus, you have to use itk::Vector as PixelType instead of itk::FixedArray, as this type provides the GetNumberOfComponents() method.
