Gmagick::motionblurimage
(PECL gmagick >= Unknown)
Gmagick::motionblurimage — Simulates motion blur
Description
public void 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 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 on success
Errors/Exceptions
Throws an GmagickException on error.
