Example

function magnifyImage($image_path /*, string $magnify_type*/)
{
    $imagick = new \Imagick(realpath($image_path));

    // This doesn't appear to work
//    if ($magnify_type !== "default") {
//        $imagick->setOption("magnify:method", $magnify_type);
//    }

    $imagick->magnifyImage();
    header("Content-Type: image/jpeg");
    echo $imagick->getImageBlob();
}
