ImageBackgroundOptions

Options for an ImageBackground

Name	Type	Description
img?	HTMLImageElement	For simple backgrounds, the image to use. Optional; you can also supply a url.
onBackgroundReady?	OnBackgroundReadyCallback	Optional function to call when the image has loaded (or otherwise claims to be ready)
type	string	Type of background to render.
url?	string	URL for the background. When type is set to BackgroundTypes.simple you can supply either this, or an Image. When type is set to BackgroundTypes.tiled, you can supply this, or you can supply a urlGenerator function instead. If you supply url and no urlGenerator, the url you supply is treated as a template for the url for any given tile, and is expected to contain {z}, {x} and {y} placeholders. The form of the URL can be anything you like as long as it has the placeholders for z, x and y. For instance: http://foo.com/{z}/{x}/{y} https://bar.com?zoom={z}&x={x}&y={y} etc
visible?	boolean	Whether or not the background should initially be visible. Defaults to true.
