* a non-integer pixel position. This class is templated
* over the input image type and the coordinate representation type
* (e.g. float or double).
*
* This function works for N-dimensional images.
*
* \warning This function work only for images with scalar pixel
* types. For vector images use VectorLinearInterpolateImageFunction.
