Imagick::sketchImage

(PECL imagick 2, PECL imagick 3)

Imagick::sketchImageSimulates a pencil sketch

Beschreibung

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. Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick-Version 6.2.9 oder höher kompiliert wurde.

Parameter-Liste

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.

$imagick = new \Imagick(realpath($imagePath));
$imagick->sketchimage($radius, $sigma, $angle);
header("Content-Type: image/jpg");
echo
$imagick->getImageBlob();
}
