Abstract
A computer-implemented method includes selecting a polygon that includes a convex shape defined by vertices represented by integer coordinates. The method also includes determining a polygon transfer function from cones defined by some of the vertices. The polygon transfer function defines image processing operations independent of the scale of the polygon.
