Abstract
A method of swipe-scanning a graphic image printed on a surface. The surface has a position-coding pattern superimposed with the graphic image. The method comprises the steps of: (i) operatively positioning a swipe scanner relative to the surface; (ii) swiping the scanner across the surface; (iii) capturing, during said swipe, successive images of portions of the graphic image; (iv) imaging, during the swipe, successive 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 the captured portions of the graphic image into a scanned graphic image.
