Imagick::motionBlurImage

(PECL imagick 2.0.0)

Imagick::motionBlurImageSimulates motion blur

Описание

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

Към момента тази функция не е документирана; наличен е единствено списъкът с аргументите й.

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.

Параметри

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.
