I'm tempted to say that the problem is that the system is not finding the
font... you'd need to include the full path to the font (and it must be
readable for the user PHP runs on behalf).
Try the following:
Just for testing put the font and the script that generates the image in the
SAME directory, so let's say you have something like this:
arial.ttf (<<-- I just copied it from my windows fonts folder)
PrintImage.php
BOTH IN THE SAME DIRECTORY...
Then, the code for PrintImage.php would look like the following...
<?php
/************************/
/* Begin PrintImage.php */
// dirname(__FILE__) means "the full path to the directory where this file
<PrintImage.php> is sitting"
$fontFile = dirname(__FILE__).'/arial.ttf';
$imW = 200;
$imH = 100;
$im = imagecreatetruecolor($imgW, $imgH);
$bgColor = imagecolorallocate($im, 238, 239, 239);
$borderColor = imagecolorallocate($im, 208, 208, 208);
$textColor = imagecolorallocate($im, 46, 60, 31);
$whiteColor = imagecolorallocate($im, 255, 255, 255);
$fontSize = 18;
$textAngle = 0;
$codeString = 'Works!';
// Print rectangle
imagefilledrectangle($im, 0, 0, $imgW, $imgH, $bgColor);
imagerectangle($im, 0, 0, $imW-1, $imH-1, $borderColor);
// Print Text (Calculate Position)
$box = imagettfbbox($fontSize, $fontAngle, $fontFile, $codeString);
$x = (int)($imgW - $box[4]) / 2;
$y = (int)($imgH - $box[5]) / 2;
imagettftext($im, $fontSize, $fontAngle, $x, $y, $textColor, $fontFile,
$codeString);
// Output... no caching
header("Content-type: image/png");
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
imagepng($im);
/* End PrintImage.php */
/**********************/
?>
Then you know what you do... you load PrintImage.php into your browser and
you'll get a nice gray rectangle with the word "Works!" in the center of it. If
you don't get that... then you have a problem that is not related to path or to
PHP per-se... maybe it's a GD issue, or the font is broken... or whatever other
issue... but this code works in windows and linux provided that you get the
"arial.ttf" in the same directory as PrintImage.php.
And... use dirname(__FILE__) or similar (meaning ABSOLUTE PATHS), as much as
possible to reference other files for inclusion or processing... doing
"./myfile.php" or "../myfile.php" leads to headaches... and usually in the
moment you can't take a headache (which is project deadlines).
Hope this helps,
