#### new Cesium.BingMapsImageryProvider(options)
Scene/BingMapsImageryProvider.js 98

  Provides tiled imagery using the Bing Maps Imagery REST API.

  Name | Type | Description
  --- | --- | ---

  `options`

  Object

  Object with the following properties:

  Name | Type | Default | Description
  --- | --- | --- | ---
  `url` | String |  | The url of the Bing Maps server hosting the imagery.

  `key`

  String

  optional The Bing Maps key for your application, which can be created at https://www.bingmapsportal.com/. If this parameter is not provided, `BingMapsApi.defaultKey` is used. If `BingMapsApi.defaultKey` is undefined as well, a message is written to the console reminding you that you must create and supply a Bing Maps key as soon as possible. Please do not deploy an application that uses Bing Maps imagery without creating a separate key for your application.

  `tileProtocol` | String |  | optional The protocol to use when loading tiles, e.g. 'http:' or 'https:'. By default, tiles are loaded using the same protocol as the page.
  `mapStyle` | String | `BingMapsStyle.AERIAL` | optional The type of Bing Maps imagery to load.
  `culture` | String | `''` | optional The culture to use when requesting Bing Maps imagery. Not all cultures are supported. See http://msdn.microsoft.com/en-us/library/hh441729.aspx for information on the supported cultures.
  `ellipsoid` | Ellipsoid |  | optional The ellipsoid. If not specified, the WGS84 ellipsoid is used.

  `tileDiscardPolicy`

  TileDiscardPolicy

  optional The policy that determines if a tile is invalid and should be discarded. If this value is not specified, a default `DiscardMissingTileImagePolicy` is used which requests tile 0,0 at the maximum tile level and checks pixels (0,0), (120,140), (130,160), (200,50), and (200,200). If all of these pixels are transparent, the discard check is disabled and no tiles are discarded. If any of them have a non-transparent color, any tile that has the same values in these pixel locations is discarded. The end result of these defaults should be correct tile discarding for a standard Bing Maps server. To ensure that no tiles are discarded, construct and pass a `NeverTileDiscardPolicy` for this parameter.

  `proxy` | Proxy |  | optional A proxy to use for requests. This object is expected to have a getURL function which returns the proxied URL, if needed.

  ##### Example:

      var bing = new Cesium.BingMapsImageryProvider({
          url : 'https://dev.virtualearth.net',
          key : 'get-yours-at-https://www.bingmapsportal.com/',
          mapStyle : Cesium.BingMapsStyle.AERIAL
      });

### Members

#### readonlycredit : Credit
Scene/BingMapsImageryProvider.js 466

  Gets the credit to display when this imagery provider is active. Typically this is used to credit the source of the imagery. This function should not be called before `BingMapsImageryProvider#ready` returns true.

#### readonlyculture : String
Scene/BingMapsImageryProvider.js 279

  The culture to use when requesting Bing Maps imagery. Not all cultures are supported. See http://msdn.microsoft.com/en-us/library/hh441729.aspx for information on the supported cultures.

#### defaultGamma : Number
Scene/BingMapsImageryProvider.js 126

  The default `ImageryLayer#gamma` to use for imagery layers created for this provider. Changing this value after creating an `ImageryLayer` for this provider will have no effect. Instead, set the layer's `ImageryLayer#gamma` property.
  Default Value: `1.0`

#### readonlyerrorEvent : Event
Scene/BingMapsImageryProvider.js 429

#### readonlyhasAlphaChannel : Boolean
Scene/BingMapsImageryProvider.js 482

  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. Setting this property to false reduces memory usage and texture upload time.

#### readonlykey : String

  Gets the Bing Maps key.

#### readonlymapStyle : BingMapsStyle
Scene/BingMapsImageryProvider.js 265

  Gets the type of Bing Maps imagery to load.

#### readonlymaximumLevel : Number
Scene/BingMapsImageryProvider.js 331

#### readonlyminimumLevel : Number
Scene/BingMapsImageryProvider.js 350

  Gets the minimum level-of-detail that can be requested. This function should not be called before `BingMapsImageryProvider#ready` returns true.
