ImageTiledLayer class final

A base class for layers that display cached maps. You would typically work with one or more sub-classes of this class.

ImageTiledLayer defines a base class for layers that display tiled map services and cached image services. This is an abstract class that can be derived in a custom class to implement a local tile data scheme. To implement a custom ImageTiledLayer, for example to load your own local tile data, you should derive from this type and supply the data for each tile as it is requested. Additionally, you must supply TileInfo that describes the tiling scheme, and an Envelope that defines the layer extent.

Implement this class if you want to create a custom tiled layer where the cached images cannot be referenced by a simple URI. If your images can be referenced by a simple URI, you should instead implement ServiceImageTiledLayer.
