IonImageryProvider

Initialization options for the TileMapServiceImageryProvider constructor

Gets the credit to display when this imagery provider is active. Typically this is used to credit the source of the imagery.

Gets an event that is raised when the imagery provider encounters an asynchronous error. By subscribing to the event, you will be notified of the error and can potentially recover from it. Event listeners are passed an instance of TileProviderError.

Gets a value indicating whether or not the images provided by this imagery provider include an alpha channel. If this property is false, an alpha channel, if present, will be ignored. If this property is true, any images without an alpha channel will be treated as if their alpha is 1.0 everywhere. When this property is false, memory usage and texture upload time are reduced.

Gets the maximum level-of-detail that can be requested.

Gets the minimum level-of-detail that can be requested. Generally, a minimum level should only be used when the rectangle of the imagery is small enough that the number of tiles at the minimum level is small. An imagery provider with more than a few tiles at the minimum level will lead to rendering problems.

Gets the proxy used by this provider.

Gets the rectangle, in radians, of the imagery provided by the instance.

Gets the tile discard policy. If not undefined, the discard policy is responsible for filtering out "missing" tiles via its shouldDiscardImage function. If this function returns undefined, no tiles are filtered.

Gets the height of each tile, in pixels.

Gets the width of each tile, in pixels.

Gets the tiling scheme used by the provider.

Gets the credits to be displayed when a given tile is displayed.

Asynchronously determines what features, if any, are located at a given longitude and latitude within a tile. This function is optional, so it may not exist on all ImageryProviders.

Requests the image for a given tile.
