Emboss image

← edgeImage   enhanceImage →
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.


function embossImage($image_path, $radius, $sigma)
    $imagick = new \Imagick(realpath($image_path));
    $imagick->embossImage($radius, $sigma);
    header("Content-Type: image/jpeg");
    echo $imagick->getImageBlob();
