template<class imType , class vecType >

void vimt_sample_profile_bilin	(	vnl_vector< vecType > &	vec,
		const vimt_image_2d_of< imType > &	image,
		const vgl_point_2d< double > &	p0,
		const vgl_vector_2d< double > &	u,
		int	n
	)

Sample along profile, using bilinear interpolation.

Profile points are p+iu, where i=[0..n-1] (world co-ordinates). Vector v is resized to n*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p

Profile points are p+i*u, where i=[0..n-1]. Vector v is resized to n*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p
