PHP Manual: Simulates motion blur

Description

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 Gmagick::motionblurimage selects a suitable radius for you. Angle gives the angle of the blurring motion.

Parameters

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.

Return Values

The Gmagick object.

Errors/Exceptions

Throws an GmagickException on error.
