Path
An abstract class that contains options and constants shared between vector overlays (Polygon, Polyline, Circle). Do not use it directly. Extends Layer.
Creation
Factory | Description |
L.svg(<Renderer options options> options?) | Creates a SVG renderer with the given options. |
Options
Option | Type | Default | Descripion |
stroke | Boolean | true | Whether to draw stroke along the path. Set it to false to disable borders on polygons or circles. |
color | String | '#3388ff' | Stroke color |
weight | Number | 3 | Stroke width in pixels |
opacity | Number | 1.0 | Stroke opacity |
lineCap | String | 'round' | A string that defines shape to be used at the end of the stroke. |
lineJoin | String | 'round' | A string that defines shape to be used at the corners of the stroke. |
dashArray | String | null | A string that defines the stroke dash pattern. Doesn't work on Canvas-powered layers in some old browsers. |
dashOffset | String | null | A string that defines the distance into the dash pattern to start the dash. Doesn't work on Canvas-powered layers in some old browsers. |
fill | Boolean | depends | Whether to fill the path with color. Set it to false to disable filling on polygons or circles. |
fillColor | String | * | Fill color. Defaults to the value of the color option |
fillOpacity | Number | 0.2 | Fill opacity. |
fillRule | String | 'evenodd' | A string that defines how the inside of a shape is determined. |
bubblingMouseEvents | Boolean | true | When true, a mouse event on this path will trigger the same event on the map (unless L.DomEvent.stopPropagation is used). |
renderer | Renderer | Use this specific instance of Renderer for this path. Takes precedence over the map's default renderer. | |
className | String | null | Custom class name set on an element. Only for SVG renderer. |
Methods
Method | Returns | Descripion |
redraw() | this | Redraws the layer. Sometimes useful after you changed the coordinates that the path uses. |
redraw() | this | Redraws the layer. Sometimes useful after you changed the coordinates that the path uses. |
setStyle(<Path options> style) | this | Changes the appearance of a Path based on the options in the Path options object. |
bringToFront() | this | Brings the layer to the top of all path layers. |
bringToBack() | this | Brings the layer to the bottom of all path layers. |
Polyline
A class for drawing polyline overlays on a map. Extends Path.
USAGE EXAMPLE
// create a red polyline from an array of LatLng points
var latlngs = [
[45.51, -122.68],
[37.77, -122.43],
[34.04, -118.2]
];
var polyline = L.polyline(latlngs, {color: 'red'}).addTo(map);
// zoom the map to the polyline
map.fitBounds(polyline.getBounds());
You can also pass a multi-dimensional array to represent a MultiPolyline shape:
// create a red polyline from an array of arrays of LatLng points
var latlngs = [
[[45.51, -122.68],
[37.77, -122.43],
[34.04, -118.2]],
[[40.78, -73.91],
[41.83, -87.62],
[32.76, -96.72]]
];
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. You can create a Polyline object with multiple separate lines (MultiPolyline) by passing an array of arrays of geographic points. |
Options
Option | Type | Default | Descripion |
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. |
noClip | Boolean | false | Disable polyline clipping. |
Methods
Method | Returns | Descripion |
toGeoJSON() | Object | Returns a GeoJSON representation of the polyline (as a GeoJSON LineString or MultiLineString Feature). |
getLatLngs() | LatLng[] | Returns an array of the points in the path, or nested arrays of points in case of multi-polyline. |
setLatLngs(<LatLng[]> latlngs) | this | Replaces all the points in the polyline with the given array of geographical points. |
isEmpty() | Boolean | Returns true if the Polyline has no LatLngs. |
getCenter() | LatLng | Returns the center (centroid) of the polyline. |
getBounds() | LatLngBounds | Returns the LatLngBounds of the path. |
addLatLng(<LatLng> latlng) | this | Adds a given point to the polyline. By default, adds to the first ring of the polyline in case of a multi-polyline, but can be overridden by passing a specific ring as a LatLng array (that you can earlier access with getLatLngs). |
Rectangle
A class for drawing rectangle overlays on a map. Extends Polygon.
USAGE EXAMPLE
// define rectangle geographical bounds
var bounds = [[54.559322, -5.767822], [56.1210604, -3.021240]];
// create an orange rectangle
L.rectangle(bounds, {color: "#ff7800", weight: 1}).addTo(map);
// zoom the map to the rectangle bounds
map.fitBounds(bounds);
Creation
Factory | Description |
L.rectangle(<LatLngBounds> latLngBounds,<Polyline pptions> options?) |
Methods
Method | Returns | Descripion |
setBounds(<LatLngBounds> latLngBounds) | this | Redraws the rectangle with the passed bounds. |
Polygon
A class for drawing polygon overlays on a map. Extends Polyline. Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.
USAGE EXAMPLE
// create a red polygon from an array of LatLng points
var latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];
var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
// zoom the map to the polygon
map.fitBounds(polygon.getBounds());
You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:
var latlngs = [
[[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
[[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
];
Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
var latlngs = [
[ // first polygon
[[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
[[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
],
[ // second polygon
[[41, -111.03],[45, -111.04],[45, -104.05],[41, -104.05]]
]
];
Creation
Factory | Description |
L.polygon(<LatLng[]> latlngs, <Polyline options> options?) |
Methods
Method | Returns | Description |
toGeoJSON() | Object | Returns a GeoJSON representation of the polygon (as a GeoJSON Polygon or MultiPolygon Feature). |
Circle
A class for drawing circle overlays on a map. Extends CircleMarker. It's an approximation and starts to diverge from a real circle closer to poles (due to projection distortion).
USAGE EXAMPLE
L.circle([50.5, 30.5], {radius: 200}).addTo(map);
Creation
Factory | Description |
L.circle(<LatLng> latlng, <Circle options> options?) | Instantiates a circle object given a geographical point, and an options object which contains the circle radius. |
L.circle(<LatLng> latlng,<Number> radius, <Circle options> options?) | Obsolete way of instantiating a circle, for compatibility with 0.7.x code. Do not use in new applications or plugins. |
Options
Option | Type | Default | Descripion |
radius | Number | Radius of the circle, in meters. |
