System and method for creating a design tool using a clockwise fill rule

Abstract

A system and method for creating a design tool using a clockwise fill rule are disclosed. The system creates a design tool for use in an editor, implemented as a feature of application on a server. The design tool provides a user interface allowing a user to create a path of contours using the design tool. For each contour, the design tool provides an interface function to categorize the contour as either a 'hole' or a “fill.” For contours designated as “hole,” the design tool automatically orders the points in a counterclockwise fashion, without user interaction. For contours designated as “fill,” the design tool automatically orders the points in a clockwise fashion, without user interaction. In instances where a contour has self-intersections resulting in regions with both clockwise and counterclockwise winding, the design tool orders the points so the majority of an area of the contour winds in a desired direction.
