Function Documentation

BLI_ewa_filter()

void BLI_ewa_filter	(	int	width,
		int	height,
		bool	intpol,
		bool	use_alpha,
		const float	uv[2],
		const float	du[2],
		const float	dv[2],
		ewa_filter_read_pixel_cb	read_pixel_cb,
		void *	userdata,
		float	result[4] )

TODO(sergey): Consider making this function inlined, so the pixel read callback could also be inlined in order to avoid per-pixel function calls.
