square instead of number

Posted on 16th Feb 2014 by admin

Hello
I do not know why but this code seems to work fine only in my xampp local insallation but not in the remote server. I just see a black square instead of the number 0000000 when I run this code in the remote server through the link http://www.arreglaordenador.com/numberimage.php

and the code in numberimage.php is:
Code: (text)
<?php
$fontDir = $rootPath . "fonts\";
$fn = (isset($_GET['fn'])) ? $_GET['fn'] : "ARIAL.ttf";
$fs = (isset($_GET['fs'])) ? $_GET['fs'] : 10;
$maxWidth = 80 * $fs;

//$colorArray = array ("red", "green", "blue", "cyan", "magenta", "yellow", "black", "white", "gray");
$colorArray = array ("black", "black", "black", "black", "black", "black", "black", "black", "black");
$color = (isset($_GET['color'])) ? $colorArray[$_GET['color']] : $colorArray[rand(0, 8)];
$txt = (isset($_GET['txt'])) ? $_GET['txt'] : "0000000";
$coords = imagettfbbox($fs, 0, $fontDir . $fn, $txt);
$w = abs($coords[4]) + 8;
$h = abs($coords[5]) + 8;
$img = imagecreatetruecolor($w, $h);
$red = imagecolorallocate($img, 255,0,0);
$green = imagecolorallocate($img, 0,255,0);
$blue = imagecolorallocate($img, 0,0,255);
$cyan = imagecolorallocate($img, 0,255,255);
$magenta = imagecolorallocate($img, 255,0,255);
$yellow = imagecolorallocate($img, 255,255,0);
$black = imagecolorallocate($img, 0,0,0);
$white = imagecolorallocate($img, 255,255,255);
$gray = imagecolorallocate($img, 127,127,127);
$fill = ($color == "white") ? $black : $white;
imagefill($img, 0, 0, $fill);
$position = 4;
if (isset($_GET['position'])) $position = $_GET['position'];

imagettftext($img, $fs, 0, 0, $h-$position, $$color, "$fontDir$fn", $txt);

header("content-type: image/jpeg");
imagejpeg($img, "", 100);
imagedestroy($img);
?>


Does any of you have any suggestion?
Thanks
