An MBTilesSource creates a thread pool that the JS engine is unable to automatically garbage-collect unless the dispose() method is invoked. If you need to dispose a map that can potentially contain MBTilesSource objects, check loadExample() in [https://github.com/mmomtchev/ol-mbtiles/blob/main/examples/index.ts#L15][27] ### Parameters * `options` **[MBTilesRasterOptions][3]** options ## MBTilesRasterOptions **Extends ImageTileOptions** Options for creating a MBTilesRasterSource ### sqlWorkers Number of parallel workers to use for retrieving tiles, @default 4 Type: [number][28] ### layers List of layer names to selectively include, @default everything Type: [Array][29]<[string][30]> ### minZoom Alternative method of specifying minZoom, mutually exclusive with tileGrid, requires explicit projection. This refers to the available zoom levels of the tiled data and it is different from the OpenLayers minZoom parameter that applies to the layer. Type: [number][28] ### maxZoom Alternative method of specifying maxZoom, mutually exclusive with tileGrid, requires explicit projection This refers to the available zoom levels of the tiled data and it is different from the OpenLayers maxZoom parameter that applies to the layer. Type: [number][28] ### tileGrid Optional tile grid, refer to the Openlayers manual Type: TileGrid ### pool Optional already open SQLiteHTTP pool (mutually exclusive with url) Type: [Promise][31]\ ### mime Optional MIME type for loaded tiles (see [https://github.com/mmomtchev/ol-mbtiles/issues/68][32]) Type: [string][30] ## MBTilesVectorSource **Extends VectorTileSource** A tile source in a remote .mbtiles file accessible by HTTP WARNING If your application continuously creates and removes MBTilesSource objects, special care must be taken to properly dispose of them. An MBTilesSource creates a thread pool that the JS engine is unable to automatically garbage-collect unless the dispose() method is invoked. If you need to dispose a map that can potentially contain MBTilesSource objects, check loadExample() in [https://github.com/mmomtchev/ol-mbtiles/blob/main/examples/index.ts#L15][27] ### Parameters * `options` **[MBTilesVectorOptions][13]** options ## MBTilesVectorOptions **Extends VectorTileOptions** Options for creating a MBTilesVectorSource ### sqlWorkers Number of parallel workers to use for retrieving tiles, @default 4 Type: [number][28] ### layers List of layer names to selectively include, @default everything Type: [Array][29]<[string][30]> ### minZoom Minimum available zoom level. This refers to the available zoom levels of the tiled data and it is different from the OpenLayers minZoom parameter that applies to the layer. Type: [number][28] ### maxZoom Maximum available zoom level. This refers to the available zoom levels of the tiled data and it is different from the OpenLayers maxZoom parameter that applies to the layer. Type: [number][28] ### pool Optional already open SQLiteHTTP pool (mutually exclusive with url) Type: [Promise][31]\ ## SQLOptions Shared options for all MBTiles ### url URL of the remote MBTiles source Type: [string][30] ### sqlWorkers Number of parallel workers to use for retrieving tiles, @default 4 Type: [number][28] ### maxSqlPageSize Maximum expected page size in bytes for SQLite3 files, @default 4096 Type: [number][28] ### sqlCacheSize Memory to use for SQLite cache in KB, @default 4096 Type: [number][28] ### backendType Use a specific backend type, @default 'shared' Type: any ## importMBTiles Automatically import MBTiles metadata and return an options object compatible with the source constructors. ### Parameters * `opt` **any** Returns **([MBTilesRasterOptions][3] | [MBTilesVectorOptions][13])** [1]: #mbtilesrastersource [2]: #parameters [3]: #mbtilesrasteroptions [4]: #sqlworkers [5]: #layers [6]: #minzoom [7]: #maxzoom [8]: #tilegrid [9]: #pool [10]: #mime [11]: #mbtilesvectorsource [12]: #parameters-1 [13]: #mbtilesvectoroptions [14]: #sqlworkers-1 [15]: #layers-1 [16]: #minzoom-1 [17]: #maxzoom-1 [18]: #pool-1 [19]: #sqloptions [20]: #url [21]: #sqlworkers-2 [22]: #maxsqlpagesize [23]: #sqlcachesize [24]: #backendtype [25]: #importmbtiles [26]: #parameters-2 [27]: https://github.com/mmomtchev/ol-mbtiles/blob/main/examples/index.ts#L15 [28]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number [29]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array [30]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String [31]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise [32]: https://github.com/mmomtchev/ol-mbtiles/issues/68
