matplotlib.textpath

class matplotlib.textpath. TextPath ( xy, s, size=None, prop=None, _interpolation_steps=1, usetex=False ) [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.

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 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 Using a text as a Path.

property codes

Return the codes

get_size ( ) [source]

Get the text size.

set_size ( size ) [source]

Set the text size.

property vertices

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 ( 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 ( 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 ( 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 ( ) [source]

Return the cached TexManager instance.

get_text_path ( prop, s, ismath=False ) [source]

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

Parameters:	prop 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.
