Struct LayerPose 

pub struct LayerPose {
    pub opacity: f64,
    pub dx: f64,
    pub dy: f64,
    pub scale: f64,
    pub wipe: Option<(Dir, f64)>,
}

How one of the two layers is drawn. Offsets are fractions of the frame (positive x moves the layer right, positive y moves it down). Scale is around the frame center. A wipe reveals that fraction of the layer from dir and hides the rest.

Fields

opacity: f64

0 is invisible, 1 is solid.

dx: f64

Horizontal shift, as a fraction of the frame width.

dy: f64

Vertical shift, as a fraction of the frame height.

scale: f64

Scale around the center. 1 leaves the layer as it is.

wipe: Option<(Dir, f64)>

Reveal this much of the layer (0..1) from this edge. None shows it all.

Implementations

impl LayerPose

pub fn new() -> Self

Fully visible, unmoved, unscaled.

pub fn opacity(self, opacity: f64) -> Self

Multiplies the layer’s alpha.

pub fn offset(self, dx: f64, dy: f64) -> Self

Shifts the layer by fractions of the frame.

pub fn scale(self, scale: f64) -> Self

Scales the layer around the center.

pub fn wipe(self, dir: Dir, amount: f64) -> Self

Shows amount of the layer (0..1) starting from dir.
