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. Examples -------- Create a list of vertices and codes from a text, and create a `.Path` from those:: from matplotlib.path import Path from matplotlib.text import TextToPath from matplotlib.font_manager import FontProperties fp = FontProperties(family="Comic Neue", 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*)r)get_glyphs_texrget_glyphs_with_fontget_glyphs_mathtextextendnpempty)rrr3r4 glyph_info glyph_maprectsrvertscodesglyph_id xposition ypositionr6verts1codes1rrr get_text_pathHs"$        zTextToPath.get_text_pathNc Cs|durt}|r t}n|}g}g}t||D]"}||jt|j} || ||j| |vr;|j || <qdgt |} dgt |} g} t t ||| | || fS)zW Convert string *s* to vertices and codes using the provided ttf font.

NFc szddlm}t|}|dur|}||_||d|_||d|\}}t j t j |||d|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)r4T)_interpolation_stepsreadonlyF)matplotlib.textrr _from_anyr-_xyr_cached_vertices_preprocess_mathsuperr text_to_pathrO_should_simplify) rxyr3rjrrrrr4 __class__rrr*s -   zTextPath.__init__cCs||_d|_dS)zSet the text size.TN)_size_invalid)rrjrrrrhs zTextPath.set_sizecC|jS)zGet the text size.)rrrrrget_sizemszTextPath.get_sizecCs||jS)zH Return the cached path after updating it if necessary. )_revalidate_pathrrrrrverticesqszTextPath.verticescCr)z" Return the codes )_codesrrrrrIyszTextPath.codescCsR|js|jdur't|jtjj|j}| |j |_d|jj _ d|_dSdS)z Update the path if necessary.
