Annotation objects can be rotated by holding the Shift key while dragging a handle
or by using the two rotation handles are displayed on a selected object. One of the
handles is the "gripper" handle, which rotates the object when dragged. The other
handle is the "center" handle, which determines the center of rotation. The center
of rotation can be moved by dragging. The gripper handle can be moved anywhere by
dragging.
The following figure illustrates moving the
"center" handle: 
The rotation handles can be reset
to a default location by right-clicking The WPF annotation object, and selecting the
Reset Rotate Control Points option, as shown in the following figure:
The rotation control points can be globally
hidden or displayed by right-clicking on the image (not a WPF Annotation object), and
selecting the Use Rotate Control Points option, as shown in the following figure:
The WPF annotation rotation handles are implemented
by the following functions:
