Question

I’m building a web application where you can design something, at the end of the process it outputs two images. One is a gif and the other is a jpeg. I am looking to take both images and merge them into one image. However after trying a few techniques none seem to work.

My script is as follows:

$imgl = $_GET['img1'];
$img2 = $_GET['img2'];


$dest = imagecreatefromjpeg('$imgl');
$src = imagecreatefromgif('$img2');

// Copy and merge
imagecopymerge($dest, $src, 10, 10, 0, 0, 100, 47, 75);

// Output and free from memory
header('Content-Type: image/gif');
imagegif($dest);

imagedestroy($dest);
imagedestroy($src);

However the image that is displayed is just shows a non image icon. The variables $img1 and $img2 contain an image path, to a folder where the images exsist. I know this because when I echo the two variables in a html img tag, both images are displayed. Can anyone tell me where my script is going wrong?

Answer 1

I know your example is directly for PHP DOC but i also tested it and it does not work for me .. with a little work around it should work

$imgl = "a.jpg";
$img2 = "f.gif";

$dest = imagecreatefromjpeg($imgl);
$src = imagecreatefromgif($img2);
imagecolortransparent($src, imagecolorat($src, 0, 0));

$src_x = imagesx($src);
$src_y = imagesy($src);
imagecopymerge($dest, $src, 0, 0, 0, 0, $src_x, $src_y, 100);

// Output and free from memory
header('Content-Type: image/gif');
imagegif($dest);

imagedestroy($dest);
imagedestroy($src);
