ITileCacheInfo Interface

Provides access to members that provide the tile cache info.

When To Use

Using the tiling scheme information in the TileCacheInfo object the client can calculate the tiles that cover any rectangular extent in map space and then retrieve tiles either directly from the virtual directory, or from the tile handler or by making GetMapTile or GetLayerTile requests against the map service.

)
public void ComputeResolutions (
);

ITileCacheInfo.ComputeScales Method

Computes scales from resolutions and current DPI.
