MapPolyline Class

This class represents a polyline on the map. The MapPolyline is responsible for adapting the visual to the current map viewport in terms of scaling and clipping.

See the Shape Layer Concept topic for an example.

Syntax

C++

Copy

public class MapPolyline : MapPolylineBase

Public Class MapPolyline

public ref class MapPolyline : public MapPolylineBase

type MapPolyline =  
    class
        inherit MapPolylineBase
    end

The MapPolyline type exposes the following members.

Constructors

	Name	Description
	MapPolyline	Initializes a new instance of the MapPolyline class.

Properties

	Name	Description
	DefiningGeometry	Gets a value that represents the geometry of the shape. (Inherited from MapPolylineBase.)
	GeoTransform	Gets or sets a method which transforms a point from one coordinate system to another. (Inherited from MapShape.)
	MapStrokeThickness	Gets or sets the map stroke thickness. (Inherited from MapShape.)
	Points	Gets or sets the points of the polyline. (Inherited from MapPolylineBase.)
	ScaleFactor	Gets or sets the scale factor. See ScaleFactorProperty. (Inherited from MapShape.)
	TransformedPoints	Gets or sets the transformed points. The transformed points are a collection of points which have been transformed to the currently applied spatial reference system. This property helps to improve performance since the point transformation is only done once. (Inherited from MapPolylineBase.)

Methods

	Name	Description
	BuildGeometry	Builds the geometry of the polyline.
	ClipShape	Clip the Polyline object.
	CurrentThickness	Retrieves the thickness for lines depending on the current scale. (Inherited from MapShape.)
	NeedsUpdate	Indicates if the update process should be started or not. (Inherited from MapShape.)
	TransformShape	Transforms the polyline object according the transformation provided by GeoTransform.
	UpdateShape	Update the properties of the shape, according the current scale of the MapView object. (Overrides MapShapeUpdateShape(MapView, UpdateMode, Boolean).)

Fields

	Name	Description
	Data	Contains the geometry provided by property DefiningGeometry. (Inherited from MapPolylineBase.)

Top

Extension Methods

	Name	Description
	Envelope	Create the minimal bounding rectangle around a shape object. (Defined by RectExtensions.)
	FindRelativeT	Finds an object of type T for a framework element which is somewhere in the visual tree. (Defined by MapElementExtensions.)
	ToJson	Converts an object to a JSON string representation. (Defined by JSONWriter.)
