ABSTRACT:
A curve conversion apparatus can automatically convert a cubic curve into a quadratic curve and automatically convert data for outline font that are constituted by cubic curves and straight lines into data for outline fonts that are constituted by quadratic curves and straight lines. According to this apparatus, control points of a cubic curve, such as a cubic Bezier curve or a cubic B spline curve, are employed to acquire control points of a quadratic curve, and the acquired control points are stored.
