1. A method, comprising: receiving a position input indicating an initial position of a stylus with respect to a tablet device, the initial position above a surface of the tablet device; determining a perpendicular motion and a parallel motion of a change in position of the stylus with respect to the tablet device above the surface of the tablet device, the perpendicular motion of the change in position of the stylus correlating to a zoom function and the parallel motion of the change in position of the stylus correlating to a pan function; and initiating a zoom and pan display of a digital image responsive to said determining the perpendicular and parallel motions of the change in position of the stylus with respect to the tablet device.
