Methods

Static clipSegment

clipSegment(a: Point, b: Point, bounds: Bounds): void

- Defined in src/typings/leaflet/leaflet.d.ts:1920
Clips the segment a to b by rectangular bounds (modifying the segment points directly!). Used by Leaflet to only show polyline points that are on the screen or near, increasing performance.

Parameters
- a: Point
- b: Point
- bounds: Bounds
Returns void

Static closestPointOnSegment

closestPointOnSegment(p: Point, p1: Point, p2: Point): number

- Defined in src/typings/leaflet/leaflet.d.ts:1913
Returns the closest point from a point p on a segment p1 to p2.

Parameters
- p: Point
- p1: Point
- p2: Point
Returns number

Static pointToSegmentDistance

pointToSegmentDistance(p: Point, p1: Point, p2: Point): number

- Defined in src/typings/leaflet/leaflet.d.ts:1908
Returns the distance between point p and segment p1 to p2.

Parameters
- p: Point
- p1: Point
- p2: Point
Returns number

Static simplify

simplify(points: Point[], tolerance: number): Point[]

- Defined in src/typings/leaflet/leaflet.d.ts:1903
Dramatically reduces the number of points in a polyline while retaining its shape and returns a new array of simplified points. Used for a huge performance boost when processing/displaying Leaflet polylines for each zoom level and also reducing visual noise. tolerance affects the amount of simplification (lesser value means higher quality but slower and with more points). Also released as a separated micro-library Simplify.js.

Parameters
- points: Point[]
- tolerance: number
Returns Point[]
