[PHP] script help please.

[Ryan Smaglik]

I got a generic �text to png on the fly� script which works fine but I want
to change it so that the image only the size of the text. (so the text has
no border, or padding around it) For and example of what I want to do check
out: http://www.spoono.com/font/?string=This is what i want to do&.png
I have the script:
<?

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

  if(!isset($s)){$s=8;}

  $size = 
imagettfbbox($s,0,"/home/xelerix/public_html/font/fonts/04B_03__.TTF",$text)
;

  $dx = abs($size[2]-$size[0]);

  $dy = abs($size[5]-$size[3]);

  $xpad=9;

  $ypad=9;

  $im = imagecreate($dx+$xpad,$dy+$ypad);

  $bg = ImageColorAllocate($im, 102,102,102);

  $white = ImageColorAllocate($im, 255,255,255);

  ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2), $white,
"/home/xelerix/public_html/font/fonts/04B_03__.TTF", $text);

  imagepng($im);

  ImageDestroy($im);

?>

The text for the image is called from a url like
www.xelerix.com/font/font.php?text=Hi

Thanks!
