Abstract
A control computer, an error calculator, a Bezier curve divider and an output device are provided for generating a character curve. Coordinates of end points and control points of a Bezier curve are input to the control computer. The error calculator determines squares of distances of the input control points from a straight line connecting the end points as errors. If these errors exceed a tolerable range, the curve divider divides the curve into two parts, and new coordinates of new end points and control points of a divided Bezier curve are input to the error calculator. The curve division and error calculation are repeatedly carried out until the calculated errors fall within the tolerable range. The end points of the respective divided curves are connected by straight lines to develop the original curve.
