Gmagick::motionblurimage
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.
