-
-    Parameters
-    ----------
-    r, c : int
-        Center coordinate of the circle.
-    radius : int
-        Radius of the circle.
-    shape : tuple
-        Image shape which is used to determine the maximum extent of output
-        pixel coordinates.  This is useful for circles that exceed the image
-        size.  If None, the full extent of the circle is used.
-
-    Returns
-    -------
-    rr, cc : integer `~numpy.ndarray`
-        Pixel coordinates of the circle.
-        May be used to directly index into an array, e.g.
-        ``img[rr, cc] = 1``.
-
-    Examples
-    --------
-    >>> from fg21sim.utils.draw import circle
-    >>> img = np.zeros((10, 10), dtype=np.uint8)
-    >>> rr, cc = circle(4, 4, 5)
