Question

I have an sprite with a few icons, about 30. I use them by setting the background position of one specific icon. But now, I want to use one icon like a image, to put them for example, in the facebook og:img metatag..

So, how can I generate the icon, by php and GD?

mydomain.com/generate_icon.php?icon_id=5

Is there any other way to do this without GD?

Answer 1

how can i do this with GD or other method.. sorry for my English!! here is an example WITH GD

$no = isset($_GET['no']) ? $_GET['no'] : 0; <---- Image Number via GET
$img = "sprites.png";
list($h, $w) = getimagesize($img);
$size = ($h < $w) ? $h : $w;

$src = imagecreatefrompng($img);
$dest = imagecreatetruecolor($size, $size);

imagecopy($dest, $src, 0, 0, 0, ($size * $no), $size, $size);

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

Usage image.php?no=5
