Imagick::motionBlurImage — Simulates motion blur
Beschreibung
Diese Funktion ist bis jetzt nicht dokumentiert. Es steht nur die Liste der Argumente zur Verfügung.
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.
Parameter-Liste
- 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.
- channel
-
Provide any channel constant that is valid for your channel mode. To apply to more than one channel, combine channeltype constants using bitwise operators. Defaults to Imagick::CHANNEL_DEFAULT. Refer to this list of channel constants. The channel argument affects only if Imagick is compiled against ImageMagick version 6.4.4 or greater.
