Circle.is_inside Circle.is_inside(point: tuple[ndarray, ndarray], delta: float = 0, for_all: bool = True) → bool Check whether one or several points lie inside the ellipse. Parameters: point (tuple[np.ndarray, np.ndarray] | np.ndarray) – Point or set of points to test. delta (float, optional) – Additional margin added to the semi-axis lengths. for_all (bool, optional) – If True, return a single boolean for all points. Returns: Inclusion test result. Return type: bool | np.ndarray
