Abstract
An automated process provides diffusion coloring of vector graphics using color points, which appear to the user as color handles. A computing device programmatically receives input from a user establishing a plurality of color handles within a source geometry specified by a set of curves. The computing device defines a mesh with a plurality of vertices distributed throughout the source geometry. A resultant color at each vertex of the plurality of vertices is determined and a diffused pixel color is programmatically set for each pixel within the source geometry by interpolating between the resultant colors at the plurality of vertices.
