thanks for explanation. I have the same problem, cannot remove plugin directory
with the font locked. It's a pity, that this problem still persists also on
Win7+PHP5.3.3.

Hello,
We cannot fix it. Freetype keeps the file handle open and windows interprets
that as a lock. Test your script on a unix system and it should work like a
charm.
thanks for your report,
pierre

I don't necessarily want to delete the file, but I want to be able to
hypothetically delete the parent directory above it :) I'm developing an image
management system that also allows for random image generation with text, and
perhaps I would need to remove a parent directory or the file itself.

Description:
------------
My computer setup is Apache 2.0.46,PHP 4.3.2, and Windows XP SP1. Only
modifications to php.ini are: 'extension=php_gd2.dll' and 'log_errors' are
enabled. Originally, I was trying to use the imagettftext() function to write
text to a png file. I used the function in a similar context as described by
the manual, and the text write was successful. However, I stumbled upon the
discovery that the font file that the function uses was locked by either the
webserver or PHP process, as I was not able to unlink or remove the font file.
I tried to isolate the problem by testing the code on Windows XP with Apache
1.3.27, Apache 2.0.46, and IIS 5.1 and either PHP 4.2.3, 4.3.2, 4.3.3RC1, or
5.0, so I am thinking that it has something to do with the operating system.
Furthermore, this problem does not occur with a webserver running Apache/PHP
4.3.2 on Linux. Also, this problem applies to various true-type font files.
The problem only goes away after I stop or restart the webserver.
In summary, there are four functions that use a font file that lock it:
imagettftext(), imagettfbbox(), imagefttext(), and imageftbbox().
Reproduce code:
---------------
$im = imagecreatefrompng('test.png');
$blue = imagecolorallocate($im, 0, 102, 255);
$font = 'tahoma.ttf';
//
// These four functions lock the font file and do not release it
//
imagettftext($im, 10, 0, 10, 25, $blue, $font, 'text');
imagettfbbox (20, 0, $font, 'text');
imagefttext ($im, 12, 0, 10, 20, 5, $font, 'text', $foo);
imageftbbox (12, 0, $font, 'text', $foo);
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
unlink($font);
Expected result:
----------------
I expect to see the png image generated and the font file unlinked.
Actual result:
--------------
The image displays fine but the font file cannot be deleted.
(Windows Error Dialog Box after manually attempting to delete arial.ttf)
Cannot delete arial: It is being used by another person or program. Close any
programs that might be using the file and try again.
