A Point2D object that represents the new position of the image.
Remarks
The points are relative to the center of the cell and the center of the image. This means that if the X and Y values are set to {0, 0}, the image will be displayed at the center of the cell.
If the cell has multiple frames, the offset value will be applied to all of the frames.
To change the offset using the mouse button, use the AddAction method to add the action to the Medical Viewer Cell. Then use the SetAction method to associate the offset action with a mouse button.
