(PECL imagick 2.0.0)

Imagick::sketchImageSimulates a pencil sketch

Beschreibung

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. Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick-Version 6.2.9 oder höher kompiliert wurde.

Parameter-Liste

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.
