Imagick::embossImage

(PECL imagick 2.0.0)
Returns a grayscale image with a three-dimensional effect
bool Imagick::embossImage ( float $radius, float $sigma )

Returns a grayscale image with a three-dimensional effect. 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 it will choose a suitable radius for you.

Parameters:
radius

The radius of the effect

sigma

The sigma of the effect

Returns:

Returns TRUE on success.

Exception:

Throws ImagickException on error.

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

?>
