Some time ago I made a script that takes some text and returns it as an image, and worked flawlessly. But I'm not sure since when a weird bug started to happen. The letters that have a (my apologies to the font geeks) "glyph" on the left get pushed to the right so the letter starts on it, but leaves space only for the main letter, hehe, I think an example should do it.

alt text

The expected result is: alt text

The "bad" one was generated, obviously, by my script, located here: http://www.esbasura.com/images/text.php?txt=The%20quick%20brown%20fox%20jumps%20over%20the%20lazy%20dog.&fnt=1&size=23&bg=lightgrey And the good one was generated by dafont here: http://img.dafont.com/preview.php?text=The%20quick%20brown%20fox%20jumps%20over%20the%20lazy%20dog.&ttf=bleeding_cowboys0&ext=1&size=23&psize=m&y=46

I'm not doing anything fancy in the script, here is the relevant part:

                imagefilledrectangle($im, 0, 0, $width, $height, $$bg);
                imagettftext($im, $size, 0, (-1*$textsize[6]), (-1*$textsize[7]), $$color, $font, $text);
//              imagefttext($im, $size, 0, (-1*$textsize[6]), (-1*$textsize[7]), $$color, $font, $text); same results using imagefttext
                imagecolortransparent($im, $$bg);
                header("Cache-Control: public"); // HTTP/1.1
                header("Content-type: image/png");
                imagepng($im);
                imagedestroy($im);
    }

I'm kind of surprised, because, as I said, it used to work flawlessly. Maybe my host changed my machine.
