MultiShapes and Virtual Earth

 

Current Virtual Earth supports pushpins, polylines, and polygons. Another commonly used shape type that is used in other mapping applications is MultiShape or MultiGeometry. Not having this in Virtual Earth has been an issue for some users. I have put together a javascript file that can be loaded after the Virtual Earth map control that creates a MultiShape class that can be used with Virtual Earth. This new shape object takes in an array of VEShape objects and has methods to add and remove shapes from the object. Many of the functionalities that exist in the VEShape class exist in the MultiShape class. The VEMap and VEShapelayer classes have been extended in order to support this adding and removing of the MultiShape objects from the map using the existing methods in Virtual Earth. This javascript file and a simple sample html file can be downloaded here:

Note: Since this extends the VEMap and VEShapeLayer classes by accessing undocumented methods in the map control it is possible that those methods may change without notice. This may result in unexpected errors occurring in the future.

Browsers tested: IE7, FF2

Virtual Earth versions tested: 5, 6, 6.1, 6.2

MultiShape Constructor

var x = new MultiShape(shapes);

Parameter

Descrption

shapes

An array of VEShape objects to be added. Optional.

 

Public Methods

These methods can be used in the same way as the equivalent methods in the VEShape object.

GetPhotoURL

Gets the shape’s "photo" URL.

GetMoreInfoURL

Gets the shape’s "more info" URL.

SetMoreInfoURL

Sets the shape’s "more info" URL.

SetZIndex

Sets the z-index value for all shapes in the MultiShape object.

GetZIndex

Gets the z-index of a pushpin shape or pushpin attached to a polyline or polygon. The default is null, unless a z-index is set for the MultiShape object.

GetID

Gets the internal identifier of the MultiShape object.

GetShapeLayer

Gets the reference to the layer containing the specified MultiShape object.

GetShapeByIndex

Retrieves a reference to a VEShape object contained in this MultiShape object based on the specified index.

 

These methods can be used in the same way as the equivalent methods in the VEShapeLayer class.

Method

Description

AddShape

Add’s a VEShape object to the MultiShape object.

DeleteShape

Remove’s a VEShape object to the MultiShape object.

GetShapeByID

Retrieves a VEShape object from a MultiShape object by it’s id.

GetBoundingRectangle

Retrieves a VELatLongRectangle which encloses all VEShapes that are in the MultiShape object

GetShapeCount

Returns the number of shapes are in the MultiShape object.

 

These are new methods which can be used with a MultiShape object.

Method

Description

GetIconLocation

Gets a VELatLong Class object of the pushpin associated with the MultiShape object.

SetIconlocation

Sets the location of the pushpin associated with the MultiShape object.

IndexOfShape

Retrieves the index of a VEShape that is in a MultiShape object.

 

Constructors

var x = MultShape.GetIconLocation();

var x = MultShape.SetIconlocation(latlong); where latlong is a VELatLong object.

var x = MultShape.IndexOfShape(shape); where shape is a VEShape object.

MultiShape properties

Property

Description

id

Extended VEMap and VEShapeLayer method’s

The following methods have been extended to work when used with MultiShape objects.

Method

Description

AddShape

Adds a MultiShape object to the map/shape layer. All VEShapes in the MultiShape object will have a parentId parameter which is the id of the MultiShape object.

DeleteShape

Deletes a MultiShape object from any layer, including the base map layer.

DeleteAllShapes

Deletes all shapes.

GetShapeByID

Retrieves a reference to a MultiShape object contained in this layer based on the specified ID.

ShowInfoBox

  1. hi, I want to set the mapview in VE3d as can be done in map control:-viewRect = new VELatLongRectangle(new VELatLong(topLeftLat,topLeftLng),new VELatLong(bottomRightLat,bottomRightLng), new VELatLong(topLeftLat,bottomRightLng),new VELatLong(bottomRightLat,topLeftLng));map.SetMapView(viewRect);How can i dot it?RegardsRamneek
