Abstract:
An embroidery data processor for preparing sewing data of an embroidery pattern based on image data of the embroidery pattern, the embroidery data processor comprising:a thinning unit t that reduces thickness of lines in the image data to produce thin-line image data including at least one thin-line outline defining a bounded region corresponding to a region of the embroidery pattern; a bounded region extractor that extracts the bounded region defined by the at least one thin-line outline, wherein the bounded region extractor includes a thin-line following unit that follows the at least one thin-line outline; a thin-line following unit that follows pixels of the at least one thin-line outline to search for branch lines connected to the at least one thin-line outline and extending into the bounded region; and a closed loop processor that, when the thin-line following unit follows a pixel of the at least one thin-line outline twice, detects a closed loop that is within the bounded region and that is connected by a connecting branch line to the at least one thin-line outline.
