zoomOnEnable
A value indicating whether the map will automatically zoom to this catalog item when it is enabled.
Note that within a single init source:
- Catalog items with both
isEnabledandzoomOnEnableset to true will override the top-levelinitialCameraproperty. - If multiple catalog items have both
isEnabledandzoomOnEnableset to true, it is undefined which one will affect the camera.
In the case of multiple init sources, however, the camera will reflect whatever happens in the last init source, whether
it is a result of a zoomOnEnable or an initialCamera,
