ABSTRACT:
Process and apparatus for producing, based on main outline segment data representative of a pair of opposed main outline segments which define an embroidery area by cooperating with a pair of opposed secondary outline segments connecting between corresponding pairs of opposed ends of the main outline segments, sets of stitch position data representative of respective stitch positions where a sewing needle of a sewing machine penetrates a work sheet to form respective stitches with a sewing thread, a stitch line consisting of a series of the stitches alternately turning at the opposed main outline segments, thereby providing an embroidery in the embroidery area. The process comprises the steps of: specifying a set of secondary outline segment shape defining data defining a shape of each of the secondary outline segments such that the shape of the each secondary outline segment is different from a straight line segment; and producing, based on the main outline segment data and the secondary outline segment shape defining data, the sets of stitch position data which are representative of respective stitch positions located on a stitch forming path alternately turning at the opposed main outline segments, the stitch forming path consisting of a plurality of path segments each of which connects between the main outline segments and has a shape influenced by the shapes of the secondary outline segments.
