Creates a new Google Model.
the configuration options
An event indicating that this Controller is invalidated. Invalidated means that data has changed and the visualization needs to be refreshed. This event fires when #invalidate is called.
Indicates whether or not credentials should be included with HTTP requests.
Set this to true if the server requires credentials, like HTTP basic authentication headers or cookies.
You should disable if the server is configured to allow cross-origin requests from all domains
(Acces-Control-Allow-Origin=*).
If the server allows CORS requests from all domains, the browser will block all requests where
credentials=true.
Once set, all subsequent HTTP requests will use the newly set value.
The default value is false.

The default value is false.
The spatial reference of the Google model. This is defined by the WGS:84 datum with a pseudo-mercator cylindrical projection. It is known as "EPSG:900913" or "EPSG:3857".
Headers to send with every HTTP request.
An object literal that represents the headers to send with every HTTP request. The property names represent HTTP header names, the property values represent the HTTP header values. This property can be set dynamically (post-construction). Once set, all subsequent HTTP requests will use the newly set headers.
Note that when custom headers are being sent to a server on another domain, the server will have to properly
respond to pre-flight CORS requests (a HTTP OPTION request sent by the browser before doing the actual request).
The server has to indicate that the header can be used in the actual request, by including it in
the pre-flight's Access-Control-Allow-Headers response header.
The default value is null.

Signals that the underlying data for the tiled images has changed. If this model is added to a map using a RasterImageLayer, calling this method will thus trigger a refresh of the visualization.
This model accesses the Static Maps API (v2) of Google to retrieve the images. Please review the Google Terms of Service carefully to determine if your application may use the Static Maps API.
For information about the static maps API, check the Google Static Maps API documentation.
Note that depending on your Google account type, different usage limits apply. One of these limits is the maximum image size that can be requested from the Google servers. If the model cannot satisfy a request for an image that is larger than the maximum image size determined by google, it will request a smaller image at a lower zoom level. This will result in a lower resolution raster visualization which will still fill the entire view.
The Google Static Map Image service can only serve images from a predetermined number of zoom levels. When an image is requested for a scale that falls in between two supported zoom levels, the more detailed zoom level is returned to obtain the best quality. Note that if the google image contains text, this text will be scaled and appear smaller than intended.
You can use a RasterImageLayer to visualize this model on a map.
//1) using an application key to configure the model var model2 = new GoogleImageModel({ requestParameters: { key: "{APPLICATION_KEY}" }); //2)configuring the proxy to sign requests when using a business account var model3 = new GoogleImageModel({ serviceUrl: "http://localhost:8072/sampleservices/gmaps/sign/staticmap", requestParameters: { client: "{CLIENT_ID}" });
