Ptv.XServer.Controls.Map.Layers Namespace |
A map is built-up with different Ptv.XServer.Controls.Map.Layers. There are several types of layers. The main types are TiledLayer, which renders map content split-up in bitmap tiles, UntiledLayer, which renders a new image whenever the map viewport changes and ShapeLayer, which can be used to display dynamic vector data. The map control has a LayerCollection to add, remove and manipulate the order and visibility of layers.
Classes| Class | Description | |
|---|---|---|
 | BaseLayer | A layer which adds one or more canvases to the map. |
| ReprojectionProvider | Provider, which is capable of matching coordinate reference systems, which
commonly do not match, because of different used projections. For example, Mercator
projection does not match Gauss-Krueger-Format.

| ViewportBeginChangedWeakEventManager |
The weak event manager for the ViewportBeginChanged event.
An event manager administrates different event listeners for a certain event source. The listeners
can be connected to the viewport end changed event and can be disconnected again if they are no more used. |
| ViewportEndChangedWeakEventManager |
The weak event manager for the ViewportEndChanged event.
An event manager administrates different event listeners for a certain event source. The listeners
can be connected to the viewport end changed event and can be disconnected again if they are no more used. |
| ViewportWhileChangedWeakEventManager |
The weak event manager for the ViewportWhileChanged event.
An event manager administrates different event listeners for a certain event source. The listeners
can be connected to the viewport end changed event and can be disconnected again if they are no more used. |
| WmsLayer | Customized layer type, which is capable of integrating Web Map Services (WMS) into the map control. |
| XMapLayerFactory |
This helper class implements extension methods to initialize the map
with xMapServer base layers, RoadEditor and POI layers available from XMapServer.
