493 <p>SketchImage() simulates a pencil sketch. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and SketchImage() selects a suitable radius for you. Angle gives the angle of the sketch.</p>
