Imagick::sketchImage

(PECL imagick 2.0.0)

Imagick::sketchImageSimulates a pencil sketch

Opis

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

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. Ta metoda jest dostępna, jeśli rozszerzenie Imagick zostało skompilowane z ImageMagick w wersji 6.2.9 lub nowszej.

Parametry

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.
