bool Imagick::motionBlurImage ( float $radius , float $sigma , float $angle [, int $channel= Imagick::CHANNEL_DEFAULT ] )

Внимание

К настоящему времени эта функция еще не была документирована; для ознакомления доступен только список аргументов.

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.

Список параметров

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.
