    1.38 +The Orientation Extension to the ImageTransform plugin.
    1.39 + 
    1.40 +The class provides the methods to set the image orientation and is intended to be implemented
    1.41 +by the plugins supporting the rotation of the image based on the orientation. The plugin
    1.42 +supporting this extension must use the opaque_data v2 format in RSS file and also the orientation flag
    1.43 +must be set in the opaque_data. The client must retrieve this extension implementation from 
    1.44 +the plugin using its extension UID.
