 ====== ThinkGeo.MapSuite.WpfDesktopEdition.Overlay ======
+{{section>upgrade_map_suite_to_10.0}}
-<!-- Class -->
 This class is the base class of all overlays in this overlay system.
-=== Remarks ===
-The &lt;strong&gt;Overlay&lt;/strong&gt; has the similar concept as the layer. Different types of overlays stack over each other to form a map. An overlay object is responsible for getting the configuration infomation from the user.Usually an overlay represents an image with transparent background that is laid upon other overlay such as &lt;strong&gt;LayerOverlay&lt;/strong&gt;, &lt;strong&gt;WmsOverlay&lt;/strong&gt;. While the &lt;strong&gt;MarkerOverlay&lt;/strong&gt; will not be rendered as an image, it is actually represents a control that holds bunch of marker images on the map.

In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

+    * Type:[[ThinkGeo.MapSuite.WpfDesktopEdition.OverlayRefreshType|OverlayRefreshType]]
+    * Description:This parameter indicates whether the elements of this overlay needs to be refreshed. For example, TileOverlay is formed by tiles. When panning the map around, the existing tile doesn't need to be redraw, the only thing we need to do is modifying the position of these tiles. On another hand, when click to change the style of the overlay, we need to redraw the tile images to change the appearance. So we need refresh mode.

+<div newline></div>
+** {{wiki:PublicMethod.gif|}} GetBoundingBox() **
+This method gets a bounding box of the Overlay.
+== Remarks ==
+This method is the concrete wrapper for the abstract method GetBoundingBoxCore. This method returns the bounding box of the Overlay. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

+  * //overlayRefreshType//
+    * Type:[[ThinkGeo.MapSuite.WpfDesktopEdition.OverlayRefreshType|OverlayRefreshType]]
+    * Description:This parameter indicates whether the elements of this overlay needs to be refreshed. For example, TileOverlay is formed by tiles. When panning or zooming the map, the existing tile doesn't need to be redraw, because the styles are the same as the previous states. the only thing we need to do is modifying the position of these tiles. On another hand, when click to change the style of the overlay, we need to redraw the tile images to change the appearance. So we need refresh mode.

-==== PanToCore(RectangleShape) ====
 This method pans the overlay to the provided world extent.
-=== Remarks ===
+== Remarks ==
 Some overlay doesn't need to continously drawing all the tile. For example, MarkerOverlay is formed by markers. When mouse down to pan, the markers don't need to redraw, we can only change its position. When mouse up to end panning, we can redraw the overlay for better performance.
