geometry.Polygon

Extends IPolygonGeometry.

The "Polygon" geometry.

See Polygon

Constructor

``geometry.Polygon([coordinates[, fillRule[, options]]])``

Parameters:

Parameter Default value Description
coordinates []

Type: Number[][][]

Geometry coordinates. A three-dimensional array of elements that are each two-dimensional coordinates of the polygon contours. The first element describes the outer contour, and the rest describe the inner contours.

fillRule "evenOdd"

Type: String

String ID that defines the polygon fill rule. Accepts one of two values:
• evenOdd - Algorithm that checks whether a point is located in the fill area by drawing a ray from this point to infinity in any direction, and counting the number of contour segments in this shape that are crossed by this ray. If the number is odd, the point is inside it; if even, the point is outside it.
• nonZero - Algorithm that checks whether a point is located in the fill area by drawing a ray from this point to infinity in any direction, and checking the points at which a segment of the shape crosses this ray. Starting from zero, one is added each time a segment crosses the ray from left to right, and one is subtracted each time a segment crosses the ray from right to left. If the result equals zero, the point is inside the contour. Otherwise, it is outside it.
options

Type: Object

Geometry options.

options.coordRendering "shortestPath"

Type: String

String ID defining the algorithm for recalculating geometry coordinates as pixel coordinates. Accepts one of two values:
• shortestPath - Algorithm that considers projection cycling on the axes and generates pixel coordinates so that the distance between two neighboring points is minimal.
• straightPath - Algorithm that does not consider projection cycling.
options.geodesic false

Type: Boolean

Enables display using geodesic lines.

options.pixelRendering "jumpy"

Type: String

Method for calculating pixel coordinates of the shape in cycled projections. This option accepts one of the following values:
• jumpy - The shape is placed as close as possible to the center of the map viewport, and can "jump" when the map is being moved.
• static - The shape is always located in the initial world and does not move when the map is moved.
options.projection

Type: IProjection

Projection.

options.simplification true

Type: Boolean

Enables simplification during rendering of a pixel geometry.

Example:

``````// Creating an instance of the polygon geometry (specifying coordinates of vertexes on contours).
var polygonGeometry = new ymaps.geometry.Polygon([
// Outer contour.
[
[0, 0], [0, 5], [5, 5], [5, 0], [0, 0]
],
// Inner contour.
[
[1, 1], [1, 2], [2, 2], [2, 1], [1, 1]
]
]);
// Creating a geo object instance and passing our geometry to the constructor.
var polygonGeoObject = new ymaps.GeoObject({ geometry: polygonGeometry });

// You can also access polygonGeometry via polygonGeoObject.geometry.``````
