Gmagick::motionblurimage — Simulates motion blur
Simulates motion blur. 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 Gmagick::motionblurimage() selects a suitable radius for you. Angle gives the angle of the blurring motion.
