Copy

public class UntiledCanvas : WorldCanvas

Public Class UntiledCanvas
	Inherits WorldCanvas

The UntiledCanvas type exposes the following members.

Constructors

	Name	Description
	UntiledCanvas(MapView, IUntiledProvider)	Initializes a new instance of the UntiledCanvas class. This method initializes the maximum request size for map bitmaps to 2048 x 2048 pixels.
	UntiledCanvas(MapView, IUntiledProvider, Boolean)	Initializes a new instance of the UntiledCanvas class. If the parameter addToMap is set to true, the new canvas instance is added to the parent map.

Properties

	Name	Description
	CanvasCategory	Gets or sets the CanvasCategory of the canvas. The canvas category defines the z order of the canvas in the map. (Inherited from MapCanvas.)
	MapView	Gets the parent map instance. (Inherited from MapCanvas.)
	MaxRequestSize	Gets or sets the maximum map bitmap request size in pixels. Default is 2048x2048.
	MinLevel	Gets or sets the maximum level up to which images are requested.
	UpdateMapObjects	Callback for a provider object to set the map objects which belong to a requested map image.

Methods

	Name	Description
	BeforeUpdate	Callback to precede the updating of the map content. (Inherited from WorldCanvas.)
	CanvasToGeo	Converts a canvas point to a geographic point. (Inherited from MapCanvas.)
	CanvasToPtvMercator	This method implements a transformation from canvas coordinates to logical coordinates. (Inherited from WorldCanvas.)
	Dispose	Disposes the map canvas. During disposal the children of the canvas are removed and the viewport changed events are disconnected. (Overrides MapCanvasDispose.)
	GeoToCanvas(Point)	Converts a geographic point to a canvas point. (Inherited from MapCanvas.)
	GeoToCanvas(Point, String)	Converts a geographic point to a canvas coordinate. (Inherited from MapCanvas.)
	InitializeTransform	Initializes the transformation instance which is needed to transform coordinates from one format to another one. (Overrides WorldCanvasInitializeTransform.)
	PtvMercatorToCanvas	This method implements a transformation from logical coordinates to canvas coordinates. (Inherited from WorldCanvas.)
	ReceiveWeakEvent	Receives events from the centralized event manager. (Inherited from MapCanvas.)
	Update	Updates the map content. The map content consists of all elements of the canvas. This method is for example triggered when the viewport changes. (Overrides MapCanvasUpdate(UpdateMode).)

Extension Methods

	Name	Description
	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.)
