Text#

Qualified name: manim.mobject.text.text\_mobject.Text

class Text(text, fill_opacity=1.0, stroke_width=0, *, color=ManimColor('#FFFFFF'), font_size=48, line_spacing=- 1, font='', slant='NORMAL', weight='NORMAL', t2c=None, t2f=None, t2g=None, t2s=None, t2w=None, gradient=None, tab_width=4, warn_missing_font=True, height=None, width=None, should_center=True, disable_ligatures=False, **kwargs)[source]#

Bases: SVGMobject

Display (non-LaTeX) text rendered using Pango.

Text objects behave like a VGroup-like iterable of all characters in the given text. In particular, slicing is possible.

Parameters:

  • text (str) – The text that needs to be created as a mobject.

  • font (str) – The font family to be used to render the text. This is either a system font or one loaded with register_font(). Note that font family names may be different across operating systems.

  • warn_missing_font (bool) – If True (default), Manim will issue a warning if the font does not exist in the (case-sensitive) list of fonts returned from manimpango.list_fonts().

  • fill_opacity (float) –

  • stroke_width (float) –

  • color (ParsableManimColor | None) –

  • font_size (float) –

  • line_spacing (float) –

  • slant (str) –

  • weight (str) –

  • t2c (dict[str, str]) –

  • t2f (dict[str, str]) –

  • t2g (dict[str, tuple]) –

  • t2s (dict[str, str]) –

  • t2w (dict[str, str]) –

  • gradient (tuple) –

  • tab_width (int) –

  • height (float) –

  • width (float) –

  • should_center (bool) –

  • disable_ligatures (bool) –

Returns:

The mobject-like VGroup.

Return type:

As Text uses Pango to render text, rendering non-English characters is easily possible:

Example: MultipleFonts

../_images/MultipleFonts-1.png 
from manim import *

class MultipleFonts(Scene):
    def construct(self):
        morning = Text("வணக்கம்", font="sans-serif")
        japanese = Text(
            "日本へようこそ", t2c={"日本": BLUE}
        )  # works same as ``Text``.
        mess = Text("Multi-Language", weight=BOLD)
        russ = Text("Здравствуйте मस नम म ", font="sans-serif")
        hin = Text("नमस्ते", font="sans-serif")
        arb = Text(
            "صباح الخير \n تشرفت بمقابلتك", font="sans-serif"
        )  # don't mix RTL and LTR languages nothing shows up then ;-)
        chinese = Text("臂猿「黛比」帶著孩子", font="sans-serif")
        self.add(morning, japanese, mess, russ, hin, arb, chinese)
        for i,mobj in enumerate(self.mobjects):
            mobj.shift(DOWN*(i-3))

class MultipleFonts(Scene):
    def construct(self):
        morning = Text("வணக்கம்", font="sans-serif")
        japanese = Text(
            "日本へようこそ", t2c={"日本": BLUE}
        )  # works same as ``Text``.
        mess = Text("Multi-Language", weight=BOLD)

_set_color_by_t2c(t2c=None)[source]#

Sets color for specified strings.

Attention

Deprecated The method Text._set_color_by_t2c has been deprecated since v0.14.0 and is expected to be removed after v0.15.0. This was internal function, you shouldn’t be using it anyway.

Sets gradient colors for specified

strings. Behaves similarly to set_color_by_t2c.

Attention

Deprecated The method Text._set_color_by_t2g has been deprecated since v0.14.0 and is expected to be removed after v0.15.0. This was internal function, you shouldn’t be using it anyway.
