[RESOLVED] Gd Text

[Pezmc]

I am using this script to generate changing text, how can I make the text always appear centered on the image?

<?php
$text = $_GET["text"];
$imgname = "images/bg.gif";

header("Content-type: image/png");

$im = imagecreatefromgif($imgname);

$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);

$font = 'fonts/neuropolx.ttf';

//This text somehow needs to be centered
imagettftext($im, 10, 0, 15, 15, $grey, $font, $text);
imagettftext($im, 10, 0, 14, 14, $black, $font, $text);

imagepng($im);
imagedestroy($im);
?>

Use imagettfbbox() to first create the text. Theres an example in the comments section in the manual how to center the text to image.

This is my script

	//Get the center
		$box = @imageTTFBbox(10,0,$font,$text);
		$width = abs($box[4] - $box[0]);
		$height = abs($box[5] - $box[1]);
		$y += $heigth/2;
		$x -= $width/2;
	// Add some shadow to the text
		imagettftext($im, 10, 0, 15, 15, $grey, $font, $text);
	// Add the text
		imagettftext($im, 10, 0, $x, $y, $black, $font, $text);

Obviously with the other stuff on however you cannot see the black text and if you echo the width and height you get -39 and 0 know why?
