Imagick::motionBlurImage — Simulates motion blur
Description
bool Imagick::motionBlurImage
( float $radius
, float $sigma
, float $angle
)
WarningThis function is
currently not documented; only its argument list is available.
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
Returns TRUE on success.
