com.supermap.services.providers.LocalTileProviderBase

com.supermap.services.providers.SMTilesMapProvider

All Implemented Interfaces:

Disposable, MapProvider, ProviderContextAware

public class SMTilesMapProvider
extends LocalTileProviderBase

SMTiles map service provider. (SMTiles is a cached file format based on the MBTiles specification extension.)

SMTilesMapProvider provides the ability to obtain a map service from a local SMTiles file or standard MBTiles file and encapsulates the GIS function associated with the SuperMap iServer map.

MBTiles is a specification that stores tile map data into the SQLite database and can be quickly used, managed, and shared. The specification is developed by MapBox.

Initializes the default map state, the return value is a map, the key is the map name, and the value is the map parameter object.

Specified by:

initDefaultMapParameter in class TiledMapProviderBase

Returns:

map state mapping, the key is the map name, and the value is the map parameter object.

getTileImage

protected byte[] getTileImage(TiledMapProviderBase.TileImageParameter tileImageParameter)
