SyntaxThe TiledCanvas type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | TiledCanvas | Initializes a new instance of the TiledCanvas class. By default, the instance is
using threading (UseThreading = true). |
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.) |
| GetTransitionUpdates | Gets or sets an function that returns a value indicating whether dynamic update is used for tile loading. |
| IsLabelLayer | Gets or sets a value indicating whether tiles are labels. |
| IsTransparentLayer | Gets or sets a value indicating whether the tiles of this layer are a transparent overlay of the
map. |
| MapView | Gets the parent map instance. (Inherited from MapCanvas.) |
| UseThreading | Gets or sets a value indicating whether threading is used for tile loading. |
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.) |
