Possible bug with imagettftext and imageft text when imagealphablending is false

I have been attempting to write a dynamic text replacement script that would generate transparent PNGs using gd, and it works fine except when one of the characters in a font has parts of it that overhang into the previous characters. You can see what I mean in this test script: <?php $img = imagecreatetruecolor(200, 200); imagealphablending($img, false); $trans = imagecolortransparent($img); imagefilledrectangle($img, 0, 0, 400, 400, $trans); $green = imagecolorallocate($img, 6, 68, 0); imagettftext($img, 30, 0, 10, 50, $green, "carolingia.ttf", "Linux"); header("Content-type: image/png"); imagesavealpha($img, true); imagepng($img); imagedestroy($img); ?> The result can be seen at http://ethilien.net/tests/text.php When you compare the text with what it should look like when I comment out the imagealphablending($img, false); line here http://ethilien.net/tests/text2.php you can see that the end of the 'u' is cut off. I think that this is because the lower-left slash of the 'x' overlaps it and causes it to be overwritten. This might be a bug in GD and not PHP, but I wanted to see if anyone has encountered this problem before or if I'm just not doing something right. Thanks, -Connor McKay
