MapViewImageCache class

Cache images wrapped into ImageItems for a MapView.

Signature:

export declare class MapViewImageCache 

Remarks

An image may have multiple names in a theme, the MapViewImageCache maps different names to the same image URL, and allows to share the image by URL to different MapViews. Within a MapView instance, the (optional) name is unique, so registering multiple images with the same name is invalid.

The MapViewImageCache uses a global to actually store (and generate) the image data.
