(PECL gmagick >= Unknown)
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 MotionBlurImage() selects a suitable radius for you. Angle gives the angle of the blurring motion.
The radius of the Gaussian, in pixels, not counting the center pixel.
The standard deviation of the Gaussian, in pixels.
Apply the effect along this angle.
