Gmagick::motionblurimageSimulates motion blur

Beschreibung

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

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.

Parameter-Liste

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.

R├╝ckgabewerte
