Public Properties

Method	Description
BingMapsViewer ( string bingMapKey, Microsoft.Xna.Framework.Graphics.Texture2D defaultImage, Microsoft.Xna.Framework.Graphics.Texture2D unavailableImage, GeoCoordinate location, int gridSize, int zoomlevel, SpriteBatch spriteBatch ) : System	Initializes new Bing maps viewer.
CenterOnLocation ( GeoCoordinate location ) : void	Centers the view on a specified geo-coordinate.
ConvertGeoCoordinateToScreenPosition ( GeoCoordinate location ) : Vector2	Convert a geo-coordinate to a coordinate on the device's display.
ConvertScreenPositionToGeoCoordinate ( Vector2 screenPosition ) : GeoCoordinate	Convert a position on the device's display to the corresponding geo-coordinate.
Draw ( ) : void	Draw the map on the screen. Assumes that SpriteBatch.Begin has been called.
MoveByOffset ( Vector2 gestureOffset ) : void	Move the map by a specified offset, but prevent a move that would transition to a tile that is off the active tile set.
RefreshImages ( ) : void	Refreshes the displayed images by getting them again from the REST services.

Initializes new Bing maps viewer.

public BingMapsViewer ( string bingMapKey, Microsoft.Xna.Framework.Graphics.Texture2D defaultImage, Microsoft.Xna.Framework.Graphics.Texture2D unavailableImage, GeoCoordinate location, int gridSize, int zoomlevel, SpriteBatch spriteBatch ) : System
bingMapKey	string	The key used to access the Bing maps service.
defaultImage	Microsoft.Xna.Framework.Graphics.Texture2D	The default image to show until actual image data is retrieved.
unavailableImage	Microsoft.Xna.Framework.Graphics.Texture2D	The image to use for tiles where an image is not available.
location	GeoCoordinate	The initial location to use.
