Sewing machine and computer-readable medium storing sewing machine control program

A non-transitory computer-readable medium storing a program to control a sewing machine that is capable of sewing an embroidery pattern on a work cloth held by an embroidery frame, the program causing a controller of the sewing machine to execute instructions of:

• acquiring information of an image, captured by an imaging device, of the work cloth onto which a marker that can be affixed onto the work cloth is affixed;
• detecting a marker position and a reference marker line based on the information of the captured image, the marker position being a position of a reference point of the marker that is affixed onto the work cloth and the reference marker line being a straight line indicating an angle with respect to a predetermined direction on the work cloth at which the marker is affixed;
• converting predefined embroidery data to identify a predefined shape of the embroidery pattern, based on a pattern position and a reference pattern line contained in predefined reference line data to identify the pattern position and the reference pattern line, the pattern position being a position of a reference point of the embroidery pattern on the work cloth at which the embroidery pattern is to be sewn, and the reference pattern line being a straight line indicating an angle with respect to the predetermined direction on the work cloth at which the embroidery pattern is to be sewn, the embroidery data being converted in such a manner that the pattern position coincides with the marker position and the reference pattern line coincides with the reference marker line;
• and
• controlling sewing of the embroidery pattern based on the embroidery data obtained after conversion.
