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

const latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];

const polygon = new Polygon(latlngs, {color: 'red'}).addTo(map);

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:

const 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.

const 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]]
]
];
