Embroidery data generating device and computer-readable medium storing embroidery data generating program

An embroidery data generating device comprising:

• a line segment data generation device that generates a plurality of line segment data pieces based on image data being an aggregation of pixels, each of the plurality of line segment data pieces including an angle component;
• a distance calculation device that calculates a distance from an ending endpoint of one of a plurality of line segments to an endpoint of another of the plurality of line segments, the plurality of line segments being respectively specified by the plurality of line segment data pieces generated by the line segment data generation device;
• an angle calculation device that calculates an angle formed by the one of the plurality of line segments and the other of the plurality of line segments;
• a connecting endpoint determination device that, based on a result of a calculation by the distance calculation device and a result of a calculation by the angle calculation device, determines which of endpoints of the plurality of line segments is a connecting endpoint to be connected to the ending endpoint;
• a line segment connecting device that connects the plurality of line segments by connecting the ending endpoint and the connecting endpoint;
• and
• an embroidery data generation device that generates embroidery data for forming stitches following the plurality of line segments connected by the line segment connecting device.
