| refreshType   | [[ThinkGeo.MapSuite.WpfDesktopEdition.OverlayRefreshType|OverlayRefreshType]]<!-- ThinkGeo.MapSuite.WpfDesktopEdition.OverlayRefreshType -->   | 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.   |

==== PanToCore(RectangleShape) ====
This method pans the overlay to the provided world extent.
=== 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.
