Embroidery data processing apparatus

摘要

An embroidery data processing apparatus includes an underlying stitch area outline device that generates an outline that defines the shape of an area to be stitched for underlying, within an area enclosed by an outline that defines the shape of an area to be embroidered. If the underlying stitch area outline has a self-intersecting portion, a dividing device divides the underlying stitch area outline into a plurality of segmental underlying stitch area outlines using the self-intersecting portion as a boundary. A point at which the underlying stitch area outline intersects itself is set as the stitching start or end point for a segmental underlying stitch area. A segmental underlying stitch data device generates stitch data for each of segmental underlying stitch areas defined by the segmental underlying stitch area outlines. An auxiliary underlying stitch data device generates auxiliary underlying stitch data for a connection between the segmental underlying stitch areas.
