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 arrays containing the (x, y) coordinates of the vertices. codes : list A list of path codes.

NFcjddlm}tj|}||}||_||d|_|||\}}tj t ||||ddd|_ dS) a 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`. _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.text 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`. r)TextN)usetex)r;T)_interpolation_stepsreadonlyF)matplotlib.textrr _from_anyr4_xyr_cached_vertices_preprocess_mathsuperr text_to_pathrW_should_simplify) rxyr:rtr rrrr; __class__s rrzTextPath.__init__*sZ )((((('-- <**,,D d $D'''88;; 6  ' 'a ' ? ?!5    !&rc"||_d|_dS)zSet the text size.TN)_size_invalid)rrts rrzTextPath.set_sizehs  rc|jS)zGet the text size.)rrs rget_sizezTextPath.get_sizems zrc8||jS)zH Return the cached path after updating it if necessary. )_revalidate_pathrrs rverticeszTextPath.verticesqs $$rc|jS)z" Return the codes )_codesrs rrQzTextPath.codesys {rc|js|jyt|jt jz j|j}| |j |_d|jj _ d|_dSdS)z Update the path if necessary.
