2
3 $dest = imagecreatefrompng('mapCanvas.png');
4 $src = imagecreatefromjpeg('si.jpg');
5 imagealphablending($dest, false);
6 imagesavealpha($dest, true);
7 // Copy and merge
8 imagecopymerge($dest, $src, 17, 13, 0, 0, 60, 100, 100);
9
10 // Output and free from memory
11 header('Content-Type: image/png');
12 imagepng($dest);
13
14 imagedestroy($dest);
15 imagedestroy($src);
