Example
Let us see another example wherein images are copied and merged with different coordinates:
<?php
$destImg = imagecreatefrompng('https://www.tutorialspoint.com/images/php.png');
$srcImg = imagecreatefrompng('https://www.tutorialspoint.com/images/Operating-System.png');
imagecopymerge($destImg, $srcImg, 10, 20, 0, 0, 390, 100, 80);
header('Content-Type: image/png');
imagegif($destImg);
imagedestroy($destImg);
imagedestroy($srcImg);
?>Output
The following is the output:
