AGSTileInfo Class Reference
Description
This object represents the tiling scheme used by a cached map service. For example, ArcGIS Server cached map service, Bing Maps, etc. The tiling scheme contains information about how a map is broken up into tiles of images and how a client can use these tiles to display a map.
