    摘要: A method and apparatus, for use with a sewing machine, for modifying stitching data representing a pattern that the sewing machine is to sew. The stitching data includes non-stitching feed data, in accordance with which the sewing machine feeds a needle without sewing from an origin position to a sewing start position, and seam data including information defining feeding directions and feed amounts per stitch, in accordance with which the sewing machine sews the pattern. A data identifying device identifies the seam data of the stitching data. A seam data changing device converts, in accordance with an enlargement/reduction ratio stored in a storage device of the sewing machine, the seam data identified by the data identifying device into new seam data representing a new pattern which is an enlarged version of the original pattern enlarged or reduced relative to the sewing start position, without modifying the non-stitching feed data. A non-stitching feed data creating device creates new non-stitching feed data. Also, a center determining or calculating device determines or calculates the center of the new pattern, so that the seam data changing device converts the seam data with reference to this center.
