Centering GD text

[Tobiaswk]

I have a script that generates an image with some text. But I have a problem.

How do I center my GD text on the image?

here is some of my code:

if ($user && $type =="forum3") {
header("Content-type: image/png");
$im = imagecreatefrompng("$type.png");
$user_width = imagettfbbox(9, 0, "$font", $text);
$x_value = (480 - ($user_width[2] + 400));
$color = imagecolorallocate($im, 255,255,255);
imagettftext($im, 48, 0, $x_value, 54, $color, "$font", $text);
imagepng($im, $forum_filnavn);
imagepng($im);
imagedestroy($im);
exit;
}

You'll need to know the width and height of your image. Divide both numbers by two and you get the x and y coordinate of the center of the image.

Then you need to figure out the width and height of your text. You can do that by using [man]imagettfbbox[/man]. You can then divide the width and height values by 2 and use these numbers to subtract from the numbers you got above.

can you give me and example of that with my code? Because its a bit confusing 🙂
