Interface AMImageScalerTracker

public interface AMImageScalerTracker

Tracks the image scalers and returns the one used for a specific MIME type.

Every image scaler registered in OSGi with the mime.type property is tracked. Multiple image scalers can be registered for the same MIME type, but the tracker returns only one.

The image scalers are grouped by mime.type and ordered by the service.ranking property. The image scaler returns the first image scaler of the group whose AMImageScaler.isEnabled() method returns true.

If no enabled image scalers are registered for the specific MIME type, it searches for the enabled image scaler with the highest service.ranking that's registered with the * MIME type. If no enabled image scalers are registered for the * MIME type, it returns null.
