Imagick::sketchImage — Simulates 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 gegendie 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.
