Imagick::sketchImage

(PECL imagick 2.0.0)

Imagick::sketchImageSimulates a pencil sketch

Описание

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. Този метод съществува ако Imagick е била компилирана за версия 6.2.9 на ImageMagick или по-нова.

Параметри

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.
