Trait piet_common::kurbo::ParamCurveExtrema[−]

pub trait ParamCurveExtrema: ParamCurve {
    pub fn extrema(&self) -> ArrayVec<[f64; 4]>;

    pub fn extrema_ranges(&self) -> ArrayVec<[Range<f64>; 5]> { ... }

    pub fn bounding_box(&self) -> Rect { ... }
}

A parametrized curve that reports its extrema.

Required methods

pub fn extrema(&self) -> ArrayVec<[f64; 4]>

Compute the extrema of the curve.

Only extrema within the interior of the curve count. At most four extrema can be reported, which is sufficient for cubic Béziers.

The extrema should be reported in increasing parameter order.

Provided methods

pub fn extrema_ranges(&self) -> ArrayVec<[Range<f64>; 5]>

Return parameter ranges, each of which is monotonic within the range.

pub fn bounding_box(&self) -> Rect

The smallest rectangle that encloses the curve in the range (0..1).
