Struct ContourMeasure 

pub struct ContourMeasure { /* private fields */ }

ContourMeasure finds positions, tangents, and segments by distance along a contour.

Create measurements with crate::Path::measure.

Implementations

impl ContourMeasure

pub fn length(&self) -> f32

length returns the contour’s total arc length.

pub fn is_closed(&self) -> bool

is_closed reports whether the source contour was explicitly closed.

pub fn sample(&self, distance: f32) -> PathSample

sample returns the position and tangent at a contour distance.

Distances clamp to the contour’s ends. NaN samples the start.

pub fn segment(&self, start: f32, end: f32) -> Option<Contour>

segment extracts the open contour between two distances.

Distances clamp to the measured contour. Empty, reversed, or NaN ranges return None.
