You can add and customize your output pictures with simple php codes like this that working with TopiLib: (You can add both image and text watermark, too)

createFromPNG($_GET['image'], true);
$img = new \TopiLib\TopiImage('watermark.png', 'transparent png');
$img->startX = 100;  //your custom start X position
$img->startY = 100;  //your custom start Y position
$panel->addImage($img);
$panel->render(); ?>
