Imagick::sketchImage

(PECL imagick 2.0.0)

Simulates 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. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer.

Parameters:

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.

Returns:

Returns TRUE on success.

Examples:

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();
}
 
?>
