template<class imType , class vecType >

void vimt_sample_grid_bilin	(	vnl_vector< vecType > &	vec,
		const vimt_image_2d_of< imType > &	image,
		const vgl_point_2d< double > &	p0,
		const vgl_vector_2d< double > &	u,
		const vgl_vector_2d< double > &	v,
		int	n1,
		int	n2
	)

Sample grid from image, using bilinear interpolation.

Grid points are p+i.u+j.v where i=[0..n1-1], j=[0..n2-1] Vector vec is resized to n1*n2*np elements, where np=image.nplanes(). vec[0]..vec[np-1] are the values from point p0 Samples are taken along direction v first, then along u. Points outside image return zero.
