Abstract
A method of beautificating a graphic pattern approximated by line segments divided by knots, includes the step (H) of moving each knot under a predetermined limited condition, the step (G) of obtaining a quality evaluation value for the graphic pattern corresponding to the moved knot, and the step (I) of obtaining a graphic pattern which corresponds to the moved knot and has a largest quality evaluation value as a beautificated graphic pattern. For all combinations of movable knots, quality evaluation values of graphic patterns corresponding to the moved knots are obtained and are compared with each other to obtain a graphic pattern having the largest quality evaluation value. Alternatively, quality evaluation values of graphic patterns are obtained upon sequential movement of the knots, and a graphic pattern having the largest quality evaluation value is obtained while sequentially selecting the moved knots corresponding to higher quality evaluation values. This invention provides a method and apparatus for beautificating line drawings.
