Imagick::adaptiveBlurImage — Adds adaptive blur filter to image
$radius
, float $sigma
, int $channel
= Imagick::CHANNEL_DEFAULT): boolAdds an adaptive blur filter to image. The intensity of an adaptive blur depends is dramatically decreased at edge of the image, whereas a standard blur is uniform across the image. Questo metodo è disponibile se Imagick è stato compilato con ImageMagick versione 6.2.9 o successive.
radius
The radius of the Gaussian, in pixels, not counting the center pixel. Provide a value of 0 and the radius will be chosen automagically.
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 channel constants using bitwise operators. Per default è Imagick::CHANNEL_DEFAULT
. Fare riferimento a questa lista di costanti di canale
Restituisce true
in caso di successo.
Lancia una ImagickException in caso di errore.
