Detailed Description

Sample grid of points with bicubic interpolation in one image and place in another.

The vil bicub source files were derived from the corresponding vil bilin files, thus the vil bilin/bicub source files are very similar. If you modify something in this file, there is a corresponding bilin file that would likely also benefit from the same change.

template<class sType , class dType >

void vil_resample_bicub	(	const vil_image_view< sType > &	src_image,
		vil_image_view< dType > &	dest_image,
		double	x0,
		double	y0,
		double	dx1,
		double	dy1,
		double	dx2,
		double	dy2,
		int	n1,
		int	n2
	)

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

dest_image(i,j,p) is sampled from the src_image at (x0+i.dx1+j.dx2,y0+i.dy1+j.dy2), where i=[0..n1-1], j=[0..n2-1] dest_image resized to (n1,n2,src_image.nplanes()) Points outside image return zero.
