(PECL gmagick >= Unknown)

Gmagick::motionblurimage — Simulates motion blur

Description

public function 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.

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.
