Imagick::sketchImage — Simulates a pencil sketch
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.
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.
Restituisce true

Example #1 Imagick::sketchImage()
<?php
function sketchImage($imagePath, $radius, $sigma, $angle) {
$imagick = new \Imagick(realpath($imagePath));
$imagick->sketchimage($radius, $sigma, $angle);
header("Content-Type: image/jpg");
echo $imagick->getImageBlob();
}
?>
