An apparatus capable of modification of an image prior to scanning by a scanning device having a scanning element, a viewing surface, a glass platen, and a controller having memory capability, includes opaque adjustable bounding strips. The bounding strips are viewable through the viewing surface of the scanning device and are located between the inside surface of the glass platen and the scanning element. The bounding strips are movable to identify a selected portion of an image to be scanned. The apparatus also includes software for performing a scan of the selected portion of the image and identifying its location, based on the location of the adjustable bounding strips.
