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%)ré) Úget_glyphs_texrÚget_glyphs_with_fontÚget_glyphs_mathtextÚlenÚnpÚarrayÚextendÚempty)rrr,r-Z glyph_infoÚ glyph_mapÚrectsrZvertsÚcodesZglyph_idZ xpositionZ ypositionr2Zverts1Zcodes1rrrÚ get_text_pathIs&(      zTextToPath.get_text_pathNc Cs°|dkrtƒ}|rtƒ}n|}g}g}xPt ||¡D]@}| |t|jƒ¡} | | ¡| |j¡| |kr4| ¡|| <q4Wdgt |ƒ} dgt |ƒ} g} t t ||| | ƒƒ|| 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. 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`. r)ÚTextN)Úusetex)r-T)Ú_interpolation_stepsÚreadonlyF)Zmatplotlib.textrvrZ _from_anyr)Ú_xyrÚ_cached_verticesZ_preprocess_mathÚsuperrÚ text_to_pathrCZ_should_simplify) rZxyr,rYrrxrwrvr-)Ú __class__rrrQs-    zTextPath.__init__cCs||_d|_dS)zSet the text size.TN)Ú_sizeÚ_invalid)rrYrrrrszTextPath.set_sizecCs|jS)zGet the text size.)r)rrrrÚget_size”szTextPath.get_sizecCs| ¡|jS)zH Return the cached path after updating it if necessary. )Ú_revalidate_pathr{)rrrrÚvertices˜szTextPath.verticescCs|jS)z" Return the codes )Ú_codes)rrrrrB szTextPath.codescCsN|js|jdkrJtƒ |jtj¡j|jŽ}|  |j ¡|_d|jj _ d|_dS)zÇ Update the path if necessary.
