Abstract

A graphic arts method and apparatus for representation via display media of arbitrary two dimensional figures are disclosed. The method and apparatus of the present invention convert raw figure data into a reduced data set which defines a two dimensional arbitrary shape, herein referred to an a bezier figure, whose edges are defined by second order parametric curves such that the edges of the bezier figure closely approximate those of the figure represented by the raw data. The bezier figure data is converted for presentation on a display medium of an image which closely approximates that of the figure.
