Imagick::sketchImage

(PECL imagick 2.0.0)

Imagick::sketchImage — Simulates a pencil sketch

Descrierea

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. Această metodă este disponibilă dacă Imagick a fost compilat cu ImageMagick de versiunea 6.2.9 sau ulterior.

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.
