A swipe scanner for scanning a graphic image printed on a surface. The surface has a position-coding pattern imposed with the graphic image. The swipe scanner comprises: (a) a first image sensor positioned for imaging portions of the surface during a swipe of the surface, each imaged portion containing part of the position-coding pattern; (b) a second image sensor for capturing, during the swipe, portions of the graphic image; and (c) a processor. The processor is configured for: determining absolute positions of the swipe scanner using the parts of the position-coding pattern; and (d) using the absolute positions to assemble the captured portions of the graphic image into a scanned graphic image.
