ABSTRACT:
A figure processing apparatus is arranged to draw a locus figure in a form in which line ("effect line") is added to an original figure to enhance a desired visual effect. A first holding part holds a figure in a bitwise expanded form, a second holding part holds an effect figure which is formed of feature points (e.g., vertices or turning points) of the original figure, and a continuously drawing part repeats the step of drawing the figure held in the first holding part and the effect figure held in the second holding part in mutually different colors or densities. An additional arrangement extracts feature points which form the effect figure held in the second holding part.
