MarkerZoomLevelSet¶
Namespace: ThinkGeo.UI.Blazor
This class represents a collection of MarkerZoomLevels that determines the appearance of markers at different zoomlevels.
public class MarkerZoomLevelSet
Inheritance Object → MarkerZoomLevelSet
Remarks:
This class represents a collection of MarkerZoomLevels. Each MarkerZoomLevel has a different scale and style definition that will be applied to a marker when it is the current zoomlevel.
The MarkerZoomLevelSet decides which zoomlevel applies its styles to the markers based on the current zoomlevel.
For example, if the current zoomlevel is level 03, and we defined the styles on that zoomlevel as follows:
markerOverlay.ZoomLevelSet.ZoomLevel04.DefaultMarkerStyle.WebImage = ...; markerOverlay.ZoomLevelSet.ZoomLevel04.DefaultMarkerStyle.Popup = ...; markerOverlay.ZoomLevelSet.ZoomLevel04.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level10;
Then no zoomlevel will apply styles to the markers. There will be no markers displayed on the screen.
But when we change the current zoomlevel to level 04, now our current zoomlevel falls into the zoomlevel range (04-10) that defines styles. This time, the ZoomlevelSet will apply the styles on zoomlevel 04 to the markers.
