ClipBase * | parentClip |
This class contains the properties of a tracked object and functions to manipulate it.
The bounding-box displacement in X and Y directions, it's width, height and rotation variation over the frames are set as openshot::Keyframe objects.
The bounding-box information over the clip's frames are saved into a protobuf file and loaded into an object of this class.
