L.Polyline

Polyline

A class for drawing polyline overlays on a map. Extends Path. Use Map#addLayer to add it to the map.

Usage example

// create a red polyline from an array of LatLng points
var polyline = L.polyline(latlngs, {color: 'red'}).addTo(map);

// zoom the map to the polyline
map.fitBounds(polyline.getBounds());

Creation

Factory	Description
`L.polyline( <LatLng[]> latlngs, <Polyline options> options? )`	Instantiates a polyline object given an array of geographical points and optionally an options object.

Options

Option	Type	Default	Description
`smoothFactor`	`Number`	`1.0`	How much to simplify the polyline on each zoom level. More means better performance and smoother look, and less means more accurate representation.

You can use Path methods and additionally the following methods:

Method	Returns	Description
`addLatLng( <LatLng> latlng )`	`this`	Adds a given point to the polyline.
`setLatLngs( <LatLng[]> latlngs )`	`this`	Replaces all the points in the polyline with the given array of geographical points.
`getLatLngs()`	`LatLng[]`	Returns an array of the points in the path.
`spliceLatLngs( <Number> index, <Number> pointsToRemove, <LatLng> latlng?, … )`	`LatLng[]`	Allows adding, removing or replacing points in the polyline. Syntax is the same as in Array#splice. Returns the array of removed points (if any).
`getBounds()`	`LatLngBounds`	Returns the LatLngBounds of the polyline.
`toGeoJSON()`	`Object`	Returns a GeoJSON representation of the polyline (GeoJSON LineString Feature).
