Zusammenfassung:	PROBLEM TO BE SOLVED: To reliably convert a circular arc into a polyline with a simple operation without performing any repeated operations. SOLUTION: A circular arc to be converted into a polyline is designated in a step S1. After this designation, the level of approximation (the maximum distance of the corresponding points) of the polyline before conversion and the circular arc after conversion is designated in a step S2. Afterwards, the edge point of the circular arc before conversion is connected to the edge point of the graphic in a step S3. When the edge point of the graphic is present ion the vicinity of the edge point, the edge points are connected to each other.
