Imagick::sketchImage — Simulates a pencil sketch
Description
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. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer.
