1. A method of swipe-scanning a graphic image pre-printed on a surface, said method comprising the steps of: (i) operatively positioning a swipe scanner relative to the surface and swiping the scanner across the surface; (ii) capturing, during said swipe, successive images of portions of the graphic image; (iii) printing, during said swipe, successive parts of a position-coding pattern onto the surface, said position-coding pattern being superimposed with said graphic image; (iv) imaging, during said swipe, portions of said surface on which said printhead has printed said parts of the position-coding pattern; (v) determining absolute positions of the scanner using the imaged parts of the position-coding pattern; and (vi) using the absolute positions to assemble said captured portions of said graphic image into a scanned graphic image.
