Struct PatternLayer 

pub struct PatternLayer {
    pub dx: f64,
    pub dy: f64,
    pub alpha: f32,
    pub scale: f64,
}

Per-child paint parameters for one frame of a pattern transition: a paint offset (added to the child’s pod origin, so paint and hit-testing move together), an opacity (composited via push_layer), and a uniform scale (composited via push_transform about the child’s centre).

Fields

dx: f64

Horizontal paint offset in logical px (added to the child’s pod origin).

dy: f64

Vertical paint offset in logical px (added to the child’s pod origin).

alpha: f32

Opacity in [0, 1] (composited via push_layer).

scale: f64

Uniform scale factor about the child’s paint centre (composited via push_transform).
