    類別 Tile

    For layer sources that provide pre-rendered, tiled images in grids that are organized by zoom levels for specific resolutions. Note that any property set in the options is set as a ol.Object property on the layer object; for example, setting title: 'My Title' in the options means that title is observable, and has get/set accessors.

    ol.render.Event

    Tile layer options.

    方法

    • Removes an event listener using the key returned by on() or once().

      參數

      • key: Object | Object[]

        The key returned by on() or once() (or an array of keys).

    • Return the level as number to which we will preload tiles up to.

      回傳 number

      The level to preload tiles up to.

    • Set the level as number to which we will preload tiles up to.

      參數

      • preload: number

        The level to preload tiles up to.

      回傳 void

    • Whether we use interim tiles on error.

      回傳 boolean

      Use interim tiles on error.

    • Set whether we use interim tiles on error.

      參數

      • useInterimTilesOnError: boolean

        Use interim tiles on error.

      回傳 void

    • Get the layer source.

      回傳 Source

      The layer source (or null if not yet set).

      stable

    • Sets the layer to be rendered on top of other layers on a map. The map will not manage this layer in its layers collection, and the callback in ol.Map#forEachLayerAtPixel will receive null as layer. This is useful for temporary layers. To remove an unmanaged layer from the map, use #setMap(null).

      To add the layer to a map and have it managed by the map, use ol.Map#addLayer instead.
