Abstract: The present invention provides a method of copying, using a substrate, object data to a clipboard of a graphical user interface operating system, the substrate having a graphical representation of the object data disposed therein or thereon, the substrate also having coded data disposed therein or thereon, the coded data identifying a plurality of locations on the substrate, the coded data also identifying a layout of the graphical representation of the object data, the method including the steps of: receiving, from a sensing device and in a computer system, indicating data, the indicating data describing movement of the sensing device relative to the substrate, the indicating data also identifying the layout of the graphical representation of the object data, the sensing device, when moved relative to the substrate, adapted to read at least some of the coded data and generate, from the at least some coded data, the indicating data; retrieving, in the computer system and using the indicating data, the object

Abstract: A method of generating a self-contained interactive clipping from a printed substrate. The substrate has a graphic image and a position-coding pattern disposed thereon. The position-coding pattern identifies an identity and a plurality of locations.

Abstract: A method (200) and apparatus (100) for compressing an image is disclosed. The image is provided as one or more runs of pixels on a scanline basis. The runs of pixels represent one or more graphical objects forming the image. For each scanline of the image, pixel difference values between each adjacent pixels of at least one run of pixels of the scanline is determined. The pixel difference values for the run of pixels are then compared to predetermined difference values. One or more coded bytes are determined for the run of pixels depending on the comparison, each of the coded bytes representing a difference value between at least two adjacent pixels of the run of pixels. The one or more coded bytes are then stored as a compressed representation of the run of pixels corresponding to the scanline of the image.
