Abstract
A method, apparatus, and article of manufacture provide the ability to render an edge effect for an object. An object is obtained in a computer-generated rendering having vector geometry. An interior geometry is created for a fill of the object. Contour geometry is created for an outline stroke that covers an edge of the object. A proximity to the edge of the object is calculated for each pixel of the object and each pixel of the contour geometry. An effect is then rendered based on the proximities.
