I'm having trouble adjusting the scale of the watermark in the following code(it's zoomed in too much):

// Load the stamp and the photo to apply the watermark to
$stamp = imagecreatefrompng(''); $im = imagecreatefromjpeg(''); // Set the margins for the stamp and get the height/width of the stamp image $marge_right = -100; $marge_bottom = -100; $sx = imagesx($stamp); $sy = imagesy($stamp); // Copy the stamp image onto our photo using the margin offsets and the photo // width to calculate positioning of the stamp. imagecopymerge($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp), 20); // Output and free memory header('Content-type: image/png'); imagepng($im); imagedestroy($im); ?>

Open in new window

Can someone help me with the math so that the watermark and photo are the same proportions?
