Public Property ZoomingSpeed As System.Double
public System.double ZoomingSpeed {get; set;}
Remarks
The default value is 0.3. The value should be between 0 and 1. A value of 1 indicates that Zoom instantly changes to target zoom. When clicking the zoom in/zoom out buttons or moving mouse wheel or double-clicking the map tiles or pressing "+/-" key, the maps should zoom in/zoom out 1 times which is called target zoom here. The property is used to specify the zooming speed from current size to the target zoom.
