I. Overview▲
This geo services plugin is a special plugin providing only an empty map. This plugin provides no services, and is intended to be used in those cases where a Map element should only show the added map items.
The Items Overlay geo services plugin can be loaded by using the plugin key "itemsoverlay".
II. Example usage▲
The following snippet shows how a Map using this plugin can be added as an overlay to display anti-aliased map items. Note that for such an overlay Map to be transparent, it is also necessary to set its color to a transparent one, such as transparent, like in the example.
