Abstract

In a shape manipulation method, relocation information is received indicative of an intended change in position of a target location on a Bezier shape, the contour of the Bezier shape being governed by control points. In response to the relocation information, new positions are determined for canonical locations on the shape based on predefined intended behaviors of the canonical locations.
