Mobjects used for displaying (non-LaTeX) text.
The simplest way to add text to your animations is to use the Text
class. It uses the Pango library to render text.
With Pango, you are also able to render non-English alphabets like 你好 or こんにちは or 안녕하세요 or مرحبا بالعالم.
Examples
class HelloWorld(Scene):
def construct(self):
text = Text('Hello world').scale(3)
self.add(text)
class TextAlignment(Scene):
def construct(self):
title = Text("K-means clustering and Logistic Regression", color=WHITE)
title.scale_in_place(0.75)
self.add(title.to_edge(UP))
t1 = Text("1. Measuring").set_color(WHITE)
t1.next_to(ORIGIN, direction=RIGHT, aligned_edge=UP)
t2 = Text("2. Clustering").set_color(WHITE)
t2.next_to(t1, direction=DOWN, aligned_edge=LEFT)
t3 = Text("3. Regression").set_color(WHITE)
t3.next_to(t2, direction=DOWN, aligned_edge=LEFT)
t4 = Text("4. Prediction").set_color(WHITE)
t4.next_to(t3, direction=DOWN, aligned_edge=LEFT)
x = VGroup(t1, t2, t3, t4).scale_in_place(0.7)
x.set_opacity(0.5)
x.submobjects[1].set_opacity(1)
self.add(x)

Functions
register_font
(font_file)[source]¶Temporarily add a font file to Pango’s search path.
This searches for the font_file at various places. The order it searches it described below.
Absolute path.
In assets/fonts
folder.
In font/
folder.
In the same directory.
font_file (Union[str, pathlib.Path]) – The font file to add.
Examples
Use with register_font(...)
to add a font file to search
path.
with register_font("path/to/font_file.ttf"):
a = Text("Hello", font="Custom Font Name")
FileNotFoundError: – If the font doesn’t exists.
AttributeError: – If this method is used on macOS.
font_file (Union[str, pathlib.Path]) –
Notes
This method of adding font files also works with CairoText
.
Important
This method is available for macOS for ManimPango>=v0.2.3
. Using this
method with previous releases will raise an AttributeError
on macOS.
remove_invisible_chars
(mobject)[source]¶Function to remove unwanted invisible characters from some mobject
mobject (SVGMobject
) – Any SVGMobject from which we want to remove unwanted invisible characters.
The SVGMobject without unwanted invisible characters.
