Simulates a pencil sketch
Description
Imagick::sketchImage(float $radius, float $sigma, float $angle): bool
Simulates a pencil sketch. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and Imagick::sketchImage() selects a suitable radius for you. Angle gives the angle of the blurring motion. 0x629
Parameters
radiusThe radius of the Gaussian, in pixels, not counting the center pixel
sigmaThe standard deviation of the Gaussian, in pixels.
angleApply the effect along this angle.
Return Values
Success
Examples
php
<?php
function sketchImage($imagePath, $radius, $sigma, $angle) {
$imagick = new \Imagick(realpath($imagePath));
$imagick->sketchimage($radius, $sigma, $angle);
header("Content-Type: image/jpg");
echo $imagick->getImageBlob();
}
?>
