The image trackable state.
None: The image is not being tracked. Note that this may be the initial state when the image is first detected.
Limit:The image is being tracked, but not as well. The situations in which an image is considered
Limited instead of
Tracking depend on the underlying AR framework. Examples that may cause
Limited tracking include:
Obscuring the image so that it is not visible to the camera.
The image is not tracked as a moving image. This can happen, for example, if the
maxNumberOfMovingImages is exceeded.
Tracking:The underlying AR SDK reports that it is actively tracking the image.
