Relevant samples

Add graphics with symbols: Use a symbol style to display a graphic on a graphics overlay.

Convex hull: Create a convex hull for a given set of points. The convex hull is a polygon with shortest perimeter that encloses a set of points. As a visual analogy, consider a set of points as nails in a board. The convex hull of the points would be like a rubber band stretched around the outermost nails.

Convex hull list: Generate convex hull polygon(s) from multiple input geometries.

PointCollection(IEnumerable<MapPoint>)

Initializes a new instance of the PointCollection class. Populates with the supplied points.

Declaration

public PointCollection(IEnumerable<MapPoint> points)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<MapPoint>	points	Populates with the supplied points

Remarks

If the input is another PointCollection a more efficient copy is made.

PointCollection(IEnumerable<MapPoint>, SpatialReference)

Initializes a new instance of the PointCollection class. The spatial reference is used if the input points don't have one.

Declaration

public PointCollection(IEnumerable<MapPoint> points, SpatialReference spatialReference)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<MapPoint>	points	Populates with the supplied points
SpatialReference	spatialReference	A spatial reference for the input points

Remarks

If the input is another PointCollection a more efficient copy is made.
