Imagick::sketchImage — Simulates a pencil sketch

설명

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. 이 메쏘드는 Imagick을 ImageMagick 6.2.9 이상으로 컴파일 했을 때만 사용할 수 있습니다.

인수

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.
