PROBLEM TO BE SOLVED: To provide a Bezier curve plotting method capable of executing a straight line approximation to a Bezier curve by operation volume smaller than that of a conventional method and plotting the straight line approximation without generating a trouble ending the straight line approximation in an unsuitable state. ;SOLUTION: A cubic Bezier curve specified by Bezier curve data is previously divided into two parts as 1st and 2nd Bezier curves (step S21). Then, straight line approximation processing consisting of an error judgment step and a division step is recursively repeated for respective Bezier curves (step S22) and the outer sides of respective defining polygons of finally obtained Bezier curves are stored as a linear segment data file F2 for the approximate straight line group of the original Bezier curve and plotted.;COPYRIGHT: (C)1999,JPO
