imagettftext cannot open font file

Using the example from php.net I get a warning, and the image is not rendered correctly. I supply a full path to the .ttf file like so: /var/www/public/myfont.ttf

PHP Warning:  imagettftext() [<a href='function.imagettftext'>function.imagettftext</a>]: Could not find/open font in <phpfile>

I am using a custom .ttf font found here. I can open the file fine in Ubuntu as a valid font file. I also attempted other fonts, with the same result.

I am using Ubuntu 10.04 LTS 32 bit, with apache2, php5, freetype6 and php5-gd installed. I also attempted to chmod 777 file and folder with ttf file, with the same result.

How can I get the example working using a custom ttf font file?

*Edit: The code I'm using:

<?php
// File is: /var/www/public/test.php
// Apart from $font variable, it's copy-pasted from php.net

// Set the content-type
header('Content-Type: image/png');

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);开发者_Python百科
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = '/var/www/public/UnmaskedBB.ttf';

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

Testing is_file and is_readable:

$font = realpath('./').'/UnmaskedBB.ttf';
echo "Font: ".$font; // /var/www/public/UnmaskedBB.ttf
echo "Is file? ".is_file($font); // 1
echo "Is readable? ".is_readable($font); // 1

You could try to insert:

putenv('GDFONTPATH=' . realpath('.'));

in front of the first imagettftext, just to make sure it is no path issue.

UPDATE

In case you are using font caches like fc-cache, don't forget to refresh it, e.g.:

sudo fc-cache -f -v

---

Try moving the ttf file in the same dir as your php file and change $font to

$font = 'UnmaskedBB.ttf';

---

Upgrading distro, including all php packages solved the issue
