◆ Vect_clean_small_angles_at_nodes()

int Vect_clean_small_angles_at_nodes	(	struct Map_info *	Map,
		int	otype,
		struct Map_info *	Err
	)

Clean small angles at nodes.

It may happen that even if the angle between 2 boundaries at node is very small, the calculated angle is 0 because of representation error. The map must be built at least on level GV_BUILD_BASE

Parameters

	Map	input map
	otype	feature type
[out]	Err	vector map where error line segments are written

Returns: number of line modifications
