Imagick::gaussianBlurImage — Blurs an image
$radius
, float $sigma
, int $channel
= Imagick::CHANNEL_DEFAULT): boolBlurs 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.
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. Refer to this list of channel constants.
Restituisce true
in caso di successo.
Lancia una ImagickException in caso di errore.

$imagick->gaussianBlurImage($radius, $sigma, $channel);
header("Content-Type: image/jpg");
