imagepstext

I just upgraded to php4.0.4pl1( so I could use zend optimizer) with t1lib.so.1, and I'm having some problems with t1lib work consistently. What is happening is when I try to center certain text on a card size image with a variable x coordinate, imagepstext will act as if $x =0. I checked to see if my function was returning the correct number and it is. This script has worked great with php3.0.12, and I even reinstalled it to see if it still worked, and it did. Here are the snippets from the script: function getx($string,$font,$size){ $bbox = imagepsbbox($string, $font, $size); $width = $bbox[2] - $bbox[0]; $x = 252 - ceil($width/2); return $x; } $x = getx($name,$font1,18); imagepstext($im, "$name", $font1, 18, $black, $white, $x, 45); IF (for example) $name = "Registered Representative" it will not center it (acts like x=0, left justified) $name = "Registered Representativ" it will not center it (acts like x=0, left justified) $name = "Registered Representati" it will center $name = "Registered Repre5entative" it will center (char "5" can be any letter but "s") Any ideas? I would hate to have to go back to using ttf again. Thanks, JR
