void vil_warp	(	const vil_image_view< sType > &	in,
		vil_image_view< dType > &	out,
		MapFunctor	mapper,
		InterpFunctor	interp
	)

Warp an image under a 2D map.

The size of the output map and the mapper defines the region of the input image to be scanned.

Parameters:

mapper,is	the inverse of the mapping from the input image's co-ordinate frame to the output image's frame. i.e. out() = in(mapper(x,y)). It should be a functor with a signature void mapper(double x_in, double y_in, double* x_out, double* y_out);
interp,is	an interpolator, with a signature similar to S vil_bilin_interp_safe(const vil_image_view<T>&, double, double, unsigned)

Note that if you want to store a warp with an image to create a registered image, the vimt library (in contrib/mul/vimt) provides efficient registered images with transforms up to projective.
