Detailed Description

The Orientation Extension to the ImageTransform plugin.

The class provides the methods to set the image orientation and is intended to be implemented by the plugins supporting the rotation of the image based on the orientation. The plugin supporting this extension must use the opaque_data v2 format in RSS file and also the orientation flag must be set in the opaque_data. The client must retrieve this extension implementation from the plugin using its extension UID.
