1. A method comprising:
receiving a raster image depicting a radial color gradient;
computing an origin point of the radial color gradient based on an orthogonality measure between a color gradient vector and a relative position vector, wherein the color gradient vector represents a color gradient at a point in the raster image, the relative position vector represents a difference between the point and the origin point, and the orthogonality measure indicates a degree of alignment between the color gradient vector and the relative position vector;
constructing a vector graphics representation of the radial color gradient based on the origin point; and
generating a vector graphics image depicting the radial color gradient based on the vector graphics representation.
