Imagick::sketchImage

(PECL imagick 2, PECL imagick 3)

Imagick::sketchImage — Simulates a pencil sketch

Description

public 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. 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.

Return Values

Returns true on success.

Examples

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();
}

?>
