class matplotlib.textpath.TextPath(xy, s, size=None, prop=None, _interpolation_steps=1, usetex=False, *args, **kwargs) [source]

Bases: matplotlib.path.Path

Create a path from the 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.

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 rcParams.

_interpolation_steps : integer, optional

(Currently ignored)

usetex : bool, optional

Whether to use tex rendering. Defaults to False.


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 Demo Text Path.


Return the codes

get_size(self) [source]

Get the text size.

is_math_text(self, s) [source]

[Deprecated] Returns True if the given string s contains any mathtext.


Deprecated since version 3.1.

set_size(self, size) [source]

Set the text size.

text_get_vertices_codes(self, prop, s, usetex) [source]

[Deprecated] Convert string s to a (vertices, codes) pair using font property prop.


Deprecated since version 3.1.


Return the cached path after updating it if necessary.

class matplotlib.textpath.TextToPath [source]

Bases: object

A class that converts strings to paths.

DPI = 72
FONT_SCALE = 100.0
get_glyphs_mathtext(self, prop, s, glyph_map=None, return_new_glyphs_only=False) [source]

Parse mathtext string s and convert it to a (vertices, codes) pair.

get_glyphs_tex(self, prop, s, glyph_map=None, return_new_glyphs_only=False) [source]

Convert the string s to vertices and codes using usetex mode.

get_glyphs_with_font(self, font, s, glyph_map=None, return_new_glyphs_only=False) [source]

Convert string s to vertices and codes using the provided ttf font.

get_texmanager(self) [source]

Return the cached TexManager instance.

get_text_path(self, prop, s, ismath=False, usetex=<deprecated parameter>) [source]

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

prop : matplotlib.font_manager.FontProperties instance

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 renderering.

usetex : bool, optional

If set, forces ismath to True. This parameter is deprecated.

verts, codes : tuple of lists

verts is a list of numpy arrays containing the x and y coordinates of the vertices. codes is a list of path codes.


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.

get_text_width_height_descent(self, s, prop, ismath) [source]
glyph_to_path(self, font, currx=0.0) [source]

[Deprecated] Convert the font's current glyph to a (vertices, codes) pair.


Deprecated since version 3.1.
