Describes the image data representation used by a gtk.image.Image.
If you want to get the image from the widget, you can only get the currently-stored representation; for instance, if the gtk.image.Image.getStorageType returns gtk.types.ImageType.Paintable, then you can call gtk.image.Image.getPaintable.
For empty images, you can request any storage type (call any of the "get" functions), but they will all return null values.
