                 *args, **kwargs):
        r"""
        Create a path from the text. Note that it simply is a path,
        not an artist. You need to use the `~.PathPatch` (or other artists)
        to draw this path onto the canvas.

        Parameters
        ----------
        xy : tuple or array of two float values
            Position of the text. For no offset, use ``xy=(0, 0)``.

        s : str
            The text to convert to a path.

        size : float, optional
            Font size in points. Defaults to the size specified via the font
            properties *prop*.

        prop : `matplotlib.font_manager.FontProperties`, optional
            Font property. If not provided, will use a default
            ``FontProperties`` with parameters from the
            :ref:`rcParams <matplotlib-rcparams>`.

        _interpolation_steps : integer, optional
            (Currently ignored)

        usetex : bool, optional
            Whether to use tex rendering. Defaults to ``False``.

        Examples
        --------
        The following creates a path from the string "ABC" with Helvetica
        font face; and another path from the latex fraction 1/2::

            from matplotlib.textpath import TextPath
            from matplotlib.font_manager import FontProperties

            fp = FontProperties(family="Helvetica", style="italic")
            path1 = TextPath((12,12), "ABC", size=12, prop=fp)
            path2 = TextPath((0,0), r"$\frac{1}{2}$", size=12, usetex=True)

        Also see :doc:`/gallery/text_labels_and_annotations/demo_text_path`.

        Notes
        -----

        Users can specify any arbitrary location for the legend using the
        *bbox_to_anchor* keyword argument. bbox_to_anchor can be an instance
        of BboxBase(or its derivatives) or a tuple of 2 or 4 floats.
        See :meth:`set_bbox_to_anchor` for more detail.

        The legend location can be specified by setting *loc* with a tuple of
        2 floats, which is interpreted as the lower-left corner of the legend
        in the normalized axes coordinate.
