readonly errorEvent : Event
engine/Source/Scene/GoogleEarthEnterpriseImageryProvider.js 446

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.

readonly hasAlphaChannel : Boolean
engine/Source/Scene/GoogleEarthEnterpriseImageryProvider.js 499

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.

readonly maximumLevel : Number|undefined
engine/Source/Scene/GoogleEarthEnterpriseImageryProvider.js 338

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

readonly minimumLevel : Number

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

readonly proxy : Proxy
engine/Source/Scene/GoogleEarthEnterpriseImageryProvider.js 283

Gets the proxy used by this provider.

readonly ready : Boolean
engine/Source/Scene/GoogleEarthEnterpriseImageryProvider.js 458

Gets a value indicating whether or not the provider is ready for use.

readonly readyPromise : Promise.<Boolean>
