Description:
------------
Certain true type fonts shows squares instead of text. Common fonts works fine (Times, Arial...) and some symbol fonts too. But weather.tff don't. You can download the font from www.diputacionavila.es/weather.ttf

Reproduce code:
---------------
<?php 
Header("Content-type: image/png"); 
$gif = ImageCreate(200,200); 
$bg =  ImageColorAllocate($gif,22,222,2); 
$ellipse = ImageColorAllocate($gif,2,200,200); 
$tx = ImageColorAllocate($gif,255,255,128); 
ImageFilledRectangle($gif,0,0,200,200,$bg); 
$black = imagecolorallocate($gif, 0,0,0);
ImageTtfText ($gif, 20, 0, 0, 90, $black, "/weather.ttf","123ABCabc...");
ImagePNG($gif); 
?> 


Expected result:
----------------
This is what I see in php5.0.2

Actual result:
--------------
This is what I see in php5.0.3 and beyond

..and the underlying freetype libs, etc. are the same in both systems? And you're reporting this bug to be in 5.1b2, even as you only talk about 5.0.2 / 3..so REALLY try the b2 before reporting something..

Freetype libs are the same in both systems. I have also tryed other versions of freetype. I'm talking about php 5.0.3 and beyond, so I've tested it in 5.0.3, 5.0.4 and 5.1.0b2 whith the same result. If I get back to 5.0.2 it works fine.

Pierre, you broke this? :)

Please provide a link to the ttf fonts causing problems. I may try to allow broken fonts. But only if the changes will not break well defined fonts.

Here you have links to some problematic fonts
http://www.diputacionavila.es/weather.ttf
http://www.diputacionavila.es/vacation.ttf
http://www.diputacionavila.es/wingdng3.ttf

If you need anything else...

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

None of these are somehow valid. Better said they completely broken. The only who do not raise a direct error is weather.

I used freetype directly and various freetype debug tools.

Fix your fonts, sorry.

First of all thaks a lot for your time and patient. Just one question more ?Why this fonts works fine in previous versions to 5.0.3 (<= 5.0.2)?
I have done a test showing four fonts, in my server with php5.0.2 this is the result http://www.diputacionavila.es/xgarbage/gif4.php, and my server with php5.1.0b2 shows this: http://rh.homelinux.net/xgarbage/gif4.php

Thanks again

I dunno but the freetype libs is my reference implementation. The fonts are definitivally not valid.

It's always somehow possible to hack and allow broken formats. But it will introduce more troubles for well formated fonts.
