ABSTRACT:
The preferred method transforms a set of closed curves, such as a typeface, font, or character. The method projects a pattern of continuous curves over the closed curves (502). The method then determines a set of intersection points of the closed curves and continuous curves (506). Cross-over points are then determined from the set of intersection points (508). Closed loops are then assembled from the cross-over points to form the transformed typeface, font or character (510).
