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 GoogleEarthEnterpriseImageryProvider#ready returns true.
The default alpha blending value of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.
Default Value: undefined
The default brightness of this provider. 1.0 uses the unmodified imagery color. Less than 1.0 makes the imagery darker while greater than 1.0 makes it brighter.
Default Value: undefined
The default contrast of this provider. 1.0 uses the unmodified imagery color. Less than 1.0 reduces the contrast while greater than 1.0 increases it.
Default Value: undefined
The default alpha blending value on the day side of the globe of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.
Default Value: undefined
The default gamma correction to apply to this provider. 1.0 uses the unmodified imagery color.
Default Value: undefined
The default hue of this provider in radians. 0.0 uses the unmodified imagery color.
Default Value: undefined
The default texture magnification filter to apply to this provider.
Default Value: undefined
The default texture minification filter to apply to this provider.
Default Value: undefined
The default alpha blending value on the night side of the globe of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.

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

requestImage(x, y, level, request)Promise.<ImageryTypes>|undefined

Requests the image for a given tile. This function should not be called before GoogleEarthEnterpriseImageryProvider#ready returns true.
Name Type Description
x Number The tile X coordinate.
y Number The tile Y coordinate.
level Number The tile level.
request Request optional The request object. Intended for internal use only.
Returns:
A promise for the image that will resolve when the image is available, or undefined if there are too many active requests to the server, and the request should be retried later.
