Expand description

Multi-channel animation tracks attached to an [OverlayShapeItem].

Each Some track replaces the matching field on the item for the frame. Tracks are independent: a shape can simultaneously translate, scale, recolour, and rotate.

Animation resolution is CPU-side in prepare(); the host must request continuous repaints while any track is active.

Fields§

§opacity: Option<AnimTrack<f32>>

Drives the item’s overall opacity multiplier. Takes precedence over the legacy [OverlayShapeItem::animation] field when both are set.

§position: Option<AnimTrack<[f32; 2]>>

Drives position (top-left in logical pixels).

§size: Option<AnimTrack<[f32; 2]>>

Drives size (width / height in logical pixels).

§fill: Option<AnimTrack<[f32; 4]>>

Drives the item’s solid fill colour. Applies only when fill is a solid colour; gradient fills are left alone.

§border: Option<AnimTrack<[f32; 4]>>

Drives border_colour.

§rotation: Option<AnimTrack<f32>>

Drives rotation in radians.

§opacity_path: Option<PathTrack<f32>>

Arbitrary path channel driving opacity. Overrides the linear opacity track and the legacy animation field when set.

§position_path: Option<PathTrack<[f32; 2]>>

Arbitrary path channel driving position. Overrides the linear position track when set.

§size_path: Option<PathTrack<[f32; 2]>>

Arbitrary path channel driving size. Overrides the linear size track when set.

§fill_path: Option<PathTrack<[f32; 4]>>

Arbitrary path channel driving the solid fill colour. Overrides the linear fill track when set.

§border_path: Option<PathTrack<[f32; 4]>>

Arbitrary path channel driving border_colour. Overrides the linear border track when set.

§rotation_path: Option<PathTrack<f32>>

Arbitrary path channel driving rotation. Overrides the linear rotation track when set.
