$s = preg_split("/\n]+/", $text);  // Array of lines
$nL = count($s);  // Number of lines

$W = ($W==0)?abs($_bx[2]-$_bx[0]):$W;
$H = ($H==0)?abs($_bx[5]-$_bx[3])+2+($nL>1?($nL*$Leading):0):$H;

$img = @imagecreate($W+8, $H) or die("Cannot Initialize new GD image stream");

$white = imagecolorallocate($img, 255,255,255);
$txtColor = imagecolorallocate($img, 255,50,0);

// Adjust padding right:

$_H = abs($_b[5]-$_b[3]);
$__H = 0;

// Use the string to determine the width of a line
$_b = imagettfbbox(F_SIZE, F_ANGLE, F_FONT, $text);
$_W = abs($_b[2]-$_b[0]);

// Final width and height
$_X = abs($W/2)-abs($_W/2);
$__H += $_H;

imagettftext($img, F_SIZE, F_ANGLE, $_X, $__H, $txtColor, F_FONT, $text);
