Examples

Example: DarkThemeBanner

from manim import *

class DarkThemeBanner(Scene):
    def construct(self):
        banner = ManimBanner()
        self.play(banner.create())
        self.play(banner.expand())
        self.wait()
        self.play(Unwrite(banner))

class DarkThemeBanner(Scene):
    def construct(self):
        banner = ManimBanner()
        self.play(banner.create())
        self.play(banner.expand())
        self.wait()
        self.play(Unwrite(banner))

Example: LightThemeBanner

from manim import *

class LightThemeBanner(Scene):
    def construct(self):
        self.camera.background_color = "#ece6e2"
        banner = ManimBanner(dark_theme=False)
        self.play(banner.create())
        self.play(banner.expand())
        self.wait()
        self.play(Unwrite(banner))

class LightThemeBanner(Scene):
    def construct(self):
        self.camera.background_color = "#ece6e2"
        banner = ManimBanner(dark_theme=False)
        self.play(banner.create())
        self.play(banner.expand())
        self.wait()
        self.play(Unwrite(banner))

Methods

create	The creation animation for Manim's logo.
expand	An animation that expands Manim's logo into its banner.
scale	Scale the banner by the specified scale factor.

Attributes

always	Call a method on a mobject every frame.
animate	Used to animate the application of any method of self.
animation_overrides
color
depth	The depth of the mobject.
fill_color	If there are multiple colors (for gradient) this returns the first one
height	The height of the mobject.
n_points_per_curve
sheen_factor
stroke_color
width	The width of the mobject.

_original__init__(dark_theme=True)

Initialize self. See help(type(self)) for accurate signature.

Parameters:

dark_theme (bool)

create(run_time=2)

The creation animation for Manim’s logo.

Parameters:

run_time (float) – The run time of the animation.

Returns:

An animation to be used in a Scene.play() call.

Return type:

AnimationGroup

expand(run_time=1.5, direction='center')

An animation that expands Manim’s logo into its banner.

The returned animation transforms the banner from its initial state (representing Manim’s logo with just the icons) to its expanded state (showing the full name together with the icons).

See the class documentation for how to use this.

Note

Before calling this method, the text “anim” is not a submobject of the banner object. After the expansion, it is added as a submobject so subsequent animations to the banner object apply to the text “anim” as well.

Parameters:

• run_time (float) – The run time of the animation.

• direction (str) – The direction in which the logo is expanded.

Returns:

An animation to be used in a Scene.play() call.

Return type:

Succession

Examples

Example: ExpandDirections

from manim import *

class ExpandDirections(Scene):
    def construct(self):
        banners = [ManimBanner().scale(0.5).shift(UP*x) for x in [-2, 0, 2]]
        self.play(
            banners[0].expand(direction="right"),
            banners[1].expand(direction="center"),
            banners[2].expand(direction="left"),
        )

class ExpandDirections(Scene):
    def construct(self):
        banners = [ManimBanner().scale(0.5).shift(UP*x) for x in [-2, 0, 2]]
        self.play(
            banners[0].expand(direction="right"),
            banners[1].expand(direction="center"),
            banners[2].expand(direction="left"),
        )

scale(scale_factor, **kwargs)

Scale the banner by the specified scale factor.

Parameters:

• scale_factor (float) – The factor used for scaling the banner.

• kwargs (Any)

Returns:

The scaled banner.
