Imagick::gaussianBlurImage — Blurs an image

Opis

bool Imagick::gaussianBlurImage ( float $radius , float $sigma [, int $channel = Imagick::CHANNEL_ALL ] )

Ostrzeżenie

Ta funkcja jest obecnie nieudokumentowana, dostępna jest jedynie lista jej argumentów.

Blurs an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, the radius should be larger than sigma. Use a radius of 0 and selects a suitable radius for you.

Parametry

radius: The radius of the Gaussian, in pixels, not counting the center pixel.
sigma: The standard deviation of the Gaussian, in pixels.
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_ALL. Refer to this list of channel constants.
