        Convert an `(N,M,2)` ndarray to a LineStringsOnImage object.

        This is the inverse of

        Parameters
        ----------
        xy : (N,M,2) ndarray or iterable of (M,2) ndarray
            Array containing the point coordinates ``N`` line strings
            with each ``M`` points given as ``(x,y)`` coordinates.
            ``M`` may differ if an iterable of arrays is used.
            Each array should usually be of dtype ``float32``.

        shape : tuple of int
            ``(H,W,[C])`` shape of the image on which the line strings are
            placed.

        Returns
        -------
        imgaug.augmentables.lines.LineStringsOnImage
            Object containing a list of ``LineString`` objects following the
            provided point coordinates.
