template<class sType , class dType >

void vimt_resample_bilin	(	const vimt_image_2d_of< sType > &	src_image,
		vimt_image_2d_of< dType > &	dest_image,
		const vgl_point_2d< double > &	p,
		const vgl_vector_2d< double > &	u,
		const vgl_vector_2d< double > &	v,
		int	n1,
		int	n2
	)		[inline]

Sample grid of points in one image and place in another, using bilinear interpolation.

dest_image(i,j,p) is sampled from the src_image at p+i.u+j.v, where i=[0..n1-1], j=[0..n2-1] in world co-ordinates.

dest_image resized to (n1,n2,src_image.nplanes())

dest_image.world2im() set up so that the world co-ordinates in src and dest match

Points outside image return zero.

dest_image.world2im() set up so that the world co-ordinates in src and dest match

Points outside image return the value of the nearest valid pixel.
