Struct KeySplineSolver 

pub struct KeySplineSolver { /* private fields */ }

The curve of a KeySpline with fixed control points, as a plain value.

A key spline is an object of the UI thread; a spline easing that a key frame animation of the compositor uses is evaluated on the render thread with this solver. It is the same algorithm, with the same search state (the parameter of the most recent progress is the next first guess).

Implementations

impl KeySplineSolver

pub fn new(x1: f64, y1: f64, x2: f64, y2: f64) -> Self

Creates the solver of the curve with the given control points.

pub fn get_spline_progress(&mut self, linear_progress: f64) -> f64

Calculates the spline progress from a linear progress.
