ABSTRACT:
A method and apparatus for inputting stitch patterns by way of a digitizer is effective to record stitching patterns which involve skipping and which extend beyond the digitizer board. In a method aspect, where stitch patterns involve skipping and the drawings of the patterns exceed beyond the digitizer plotting board, a method is provided including the steps of commanding scale-down input coordinate values and converting the input coordinate values to scale-up values to recover the reduced value. In an apparatus aspect, an input device is provided comprising a digitizer for drawing stitching patterns, control circuitry for performing scaling function, and command generating circuitry for commencing the scaling activity.
