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.

반환값

성공시에 TRUE를 반환합니다.
