        Convert text *s* to path (a tuple of vertices and codes for
        matplotlib.path.Path).

        Parameters
        ----------
        prop : `~matplotlib.font_manager.FontProperties`
            The font properties for the text.

        s : str
            The text to be converted.

        ismath : {False, True, "TeX"}
            If True, use mathtext parser.  If "TeX", use tex for rendering.

        Returns
        -------
        verts : list
            A list of numpy arrays containing the x and y coordinates of the
            vertices.

        codes : list
            A list of path codes.

        Examples
        --------
        Create a list of vertices and codes from a text, and create a `.Path`
        from those::

            from matplotlib.path import Path
            from matplotlib.textpath import TextToPath
            from matplotlib.font_manager import FontProperties

            fp = FontProperties(family="Humor Sans", style="italic")
            verts, codes = TextToPath().get_text_path(fp, "ABC")
            path = Path(verts, codes, closed=False)

        Also see `TextPath` for a more direct way to create a path from a text.

        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<customizing-with-dynamic-rc-settings>`.

        _interpolation_steps : int, optional
            (Currently ignored)

        usetex : bool, default: False
            Whether to use tex rendering.

        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`.
