Gmagick::motionblurimage — Simulates motion blur

Descrierea

public Gmagick Gmagick::motionblurimage ( float $radius , float $sigma , float $angle )

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.

Parametri

radius: The radius of the Gaussian, in pixels, not counting the center pixel.
sigma: The standard deviation of the Gaussian, in pixels.
angle: Apply the effect along this angle.
