Imagick Functions

Imagick::motionBlurImage

Description:

bool Imagick::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.

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.

Example

<?php
header("Content-type: image/jpeg");
$image = new Imagick("opossum.jpg"); 
$image->motionblurImage(40,5,45);
echo $image;
?>
