METHOD AND APPARATUS FOR REPRESENTATION OF A CURVE OF UNIFORM WIDTH

摘要

A graphic arts method and apparatus for representation on suitable media of curves having uniform widths is disclosed. A method and apparatus of the present invention converts curve figure data into a reduced data set which defines a plurality of interconnected curve segments defined by second order parametric Bezier curves and straight line segments. Each of the curve segments is converted into a plurality of straight line segments closely approximating the shape of the associated curve segments. The vertices of rectangles associated with each of the straight line segments are than determined such that the rectangles have a width substantially equal to the required width of the curve. The rectangle data is then presentated upon suitable media as an image which closely approximates that of a curve having uniform width.
