Polygon

Definition

Polygon encloses an arbitrary 2-dimensional area on a Map. Polygons can be used for drawing a perimeter, such as a campus, city, or country. Polygons begin as basic triangles. New vertices can be created by dragging the midpoint of a polygon away from the edge. Clicking on a vertex will remove the vertex, but a minimum of 3 vertices must exist at all times.

Properties

Description

Sets or gets the description displayed in the info window. The info window appears when the user taps on the Polygon.

Draggable

Sets or gets whether or not the user can drag a map feature. This feature is accessed by long-pressing and then dragging the Polygon to a new location.

EnableInfobox

Enables or disables the infobox window display when the user taps the Polygon.

FillColor

Sets or gets the color used to fill in the Polygon.

FillOpacity

Sets or gets the opacity of the color used to fill the Polygon. A value of 0.0 will be completely invisible and a value of 1.0 will be completely opaque.

HolePoints

Specifies the points of any holes in the Polygon. The HolePoints property is a list of lists, with each sublist containing (latitude, longitude) points representing a hole.

HolePointsFromString

Specifies holes in a Polygonfrom a GeoJSON string. In contrast to HolePoints, the longitude of each point comes before the latitude as stated in the GeoJSON specification.

Points

Specifies the Points used for drawing the Polygon. The Points are specified as a list of lists containing latitude and longitude values, such as [[lat1, long1], [lat2, long2], ...].

PointsFromString

Specifies the points for the Polygon from a GeoJSON string. Unlike Points, this property expects that the longitude comes first in the point rather than the latitude.

StrokeColor

Sets or gets the color used to outline the Polygon.

StrokeOpacity

Sets or gets the opacity of the outline of the Polygon. A value of 0.0 will be invisible and a value of 1.0 will be opaque.

StrokeWidth

Sets or gets the width of the stroke used to outline the Polygon.

Title

Sets or gets the title displayed in the info window that appears when the user clicks on the map feature.

Type

Returns the type of the feature. For polygons, this returns MapFeature.Polygon (“Polygon”).

Visible

Specifies whether the Polygon should be visible on the screen. Value is true if the Polygon is showing and false if hidden.
