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. r-)get_glyphs_texrget_glyphs_with_fontget_glyphs_mathtextlennparrayextend)rrr8r9 glyph_info glyph_maprectsrvertscodesglyph_id xposition ypositionr?verts1codes1rrr get_text_pathRs$(        zTextToPath.get_text_pathNcCs|durt}|r t}n|}g}g}t|t||D]"\}\} } ||t|} || || | |vr>||| <qdgt|} dgt|} g}t t||| | ||fS)zW Convert string *s* to vertices and codes using the provided ttf font.

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.
