Struct PipKeyframe

Source

pub struct PipKeyframe {
    pub time: i64,
    pub pos_x: f64,
    pub pos_y: f64,
    pub scale_x: f64,
    pub scale_y: f64,
    pub opacity: f64,
}

Expand description

A single keyframe that defines (position_x, position_y, scale_x, scale_y, opacity) at a given timeline position.

All values are in normalised coordinates where the primary frame occupies the unit square [0.0, 1.0] × [0.0, 1.0]:

pos_x / pos_y — top-left anchor of the PiP window.
scale_x / scale_y — fraction of the primary frame’s width/height.
opacity — 0.0 (invisible) … 1.0 (fully opaque).

Fields§

§time: i64

Timeline position (timebase units).

§pos_x: f64

Horizontal position (normalised, 0.0 = left edge).

§pos_y: f64

Vertical position (normalised, 0.0 = top edge).

§scale_x: f64

Horizontal scale (fraction of primary width).

§scale_y: f64

Vertical scale (fraction of primary height).

§opacity: f64

Opacity (0.0–1.0).

Implementations§

Source §

impl PipKeyframe

Source

pub fn new(time: i64, pos_x: f64, pos_y: f64, scale: f64, opacity: f64) -> Self

Source

pub fn with_scale_xy( time: i64, pos_x: f64, pos_y: f64, scale_x: f64, scale_y: f64, opacity: f64, ) -> Self

Create a keyframe with independent horizontal and vertical scale.
