Parameters¶
boundingBox
RectangleShape
This parameter is the extent in world coordinate for requesting markers.
Returns¶
GeoCollection<Marker>
An marker collection for drawing.
Remarks:
This is a wrapper method for the abstract method GetDrawingMarkersCore.
GetMarkersForDrawingCore(RectangleShape)¶
This abstract method gets a collection of marker for drawing on the overlay.

Parameters¶
boundingBox
RectangleShape
This parameter is the extent in world coordinate for creating markers.
Returns¶
GeoCollection<Marker>
A collection of markers which are used for placing on the overlay.
Remarks:
When implementing this method, consider requesting points in the provided world extent, then create marker controls from these points.
DrawAsyncCore(RectangleShape, OverlayRefreshType, CancellationToken)¶
This method creates markers in the provided world extent and places on the overlay.
