如何在Imagick PHP的右侧放置水印？

Question

Edit

Full explenation

// Calculate coordinates of top left corner
// of the sprite inside of the image
// "- 10" stands for offset to image border
$left = $imageWidth - $spriteWidth - 10;
$top = $imageHeight - $spriteHeight - 10;

$image->compositeImage($sprite,
        Imagick::COMPOSITE_DEFAULT,
        $left, $top);
