Abstract: A method of stroking a curved path with a fill of pre-determined thickness, where the path has line segments defined by a number of points, the method being performed by forming a number of projection lines normal to the curved path at the points, where each of the projection lines has a length based on the fill thickness, determining an intersection between a set of the projection lines, the intersection indicating the occurrence of a void in stroking the curved path, and then constructing one or more polygons filling in the void in the stroked path.

Abstract: A method of stroking a curved path with a fill of pre-determined thickness, said path having line segments defined by a plurality of points, said method comprising the steps of: forming a plurality of projection lines normal to the curved path at the plurality of points, each of the projection lines having a length based on the pre-determined fill thickness; determining an intersection between a set of the plurality of projection lines, said intersection indicating an occurrence of a void in stroking the curved path; and in response to detecting said intersection of the set of projection lines, constructing at least one polygon filling in the void in the stroked path.
