Struct SimplifyBezPath

pub struct SimplifyBezPath(Vec<SimplifyCubic>);

A Bézier path which has been prepared for simplification.

See the module-level documentation for a bit more discussion of the approach, and how this struct is to be used.

Tuple Fields

0: Vec<SimplifyCubic>

Implementations

impl SimplifyBezPath

pub fn new(path: impl IntoIterator<Item = PathEl>) -> Self

Set up a new Bézier path for simplification.

Currently this is not dealing with discontinuities at all, but it could be extended to do so.

fn scale(&self, t: f64) -> (usize, f64)

Resolve a t value to a cubic.

Also return the resulting t value for the selected cubic.

fn moment_integrals(&self, i: usize, range: Range<f64>) -> (f64, f64, f64)

Trait Implementations

impl ParamCurveFit for SimplifyBezPath

fn sample_pt_deriv(&self, t: f64) -> (Point, Vec2)

Evaluate the point and derivative at parameter t.

fn sample_pt_tangent(&self, t: f64, _: f64) -> CurveFitSample

Evaluate the curve and its tangent at parameter t.

fn moment_integrals(&self, range: Range<f64>) -> (f64, f64, f64)

Compute moment integrals.

fn break_cusp(&self, _: Range<f64>) -> Option<f64>

Find a cusp or corner within the given range.
