Zoom

Zoom transition using scale transforms and opacity.

The outgoing scene zooms and fades while the incoming scene zooms in from the opposite direction. Directions: - "in": Outgoing zooms in (grows), incoming zooms in from small - "out": Outgoing zooms out (shrinks), incoming zooms out from large

Constructor

Zoom(
    direction: ZoomDirection = 'in',
    duration: float = 0.5,
    easing: Callable[[float], float] = <function linear at 0x107ad0cc0>,
    max_scale: float = 2.0,
    overlapping: bool = False
) -> None

Initialize a zoom transition.

Parameters

direction: Zoom direction ("in" or "out")
duration: Duration of the transition
easing: Easing function applied to zoom/opacity
max_scale: Maximum scale factor at full zoom (default 2.0)
overlapping: If True, scenes continue animating during transition

Methods

composite

composite(
    scene_out: 'VScene',
    scene_in: 'VScene',
    progress: float,
    time_out: float,
    time_in: float,
    ctx: RenderContext
) -> Drawing

Composite scenes with zoom effect.

Parameters

scene_out: The outgoing scene
scene_in: The incoming scene
progress: Progress through transition (0.0-1.0), already eased
time_out: Current time within outgoing scene (0.0-1.0)
time_in: Current time within incoming scene (0.0-1.0)
ctx: Render context

Returns

Drawing with zooming scenes
