1. A method comprising:
receiving a raster image depicting a radial color gradient;
computing a radial disk model for the radial color gradient, wherein the radial disk model defines a plurality of disks with centers aligned in a same direction;
computing an eccentricity vector of the radial disk model, wherein the eccentricity vector corresponds to a quotient of a difference between the centers of the plurality of disks and a difference between corresponding radii of the plurality of disks;
constructing a vector graphics representation of the radial color gradient based on the radial disk model and the eccentricity vector; and
generating a vector graphics image depicting the radial color gradient based on the vector graphics representation.
