Imagick::sketchImageSimulates a pencil sketch


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. Questo metodo è disponibile se Imagick è stato compilato con ImageMagick versione 6.2.9 o successive.

Elenco dei parametri


The radius of the Gaussian, in pixels, not counting the center pixel
