Imagick::sketchImage

(PECL imagick 2, PECL imagick 3)

Imagick::sketchImageSimulates a pencil sketch

Descrizione

public Imagick::sketchImage(float $radius, float $sigma, float $angle): bool

Simulates a pencil sketch. 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 Imagick::sketchImage() selects a suitable radius for you. Angle gives the angle of the blurring motion. Questo metodo è disponibile se Imagick è stato compilato con ImageMagick versione 6.2.9 o successive.

Elenco dei parametri

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.

Valori restituiti

Restituisce true in caso di successo.
