New Comment:
The bug occurs in the two PHP versions I have available to test on
here. Perhaps I can try on a win32 box when I get to work.
PHP 5.3.3-dev compiled from src

Which GD library do you use? Bundled?
[2010-02-09 06:39:41] sks76543210 at gmail dot com
Description:
imagettftext() and imagettfbbox() both return wrong bounding box if the
angle is not set to 0. This sounds similar to a bug closed last year at
http://bugs.php.net/bug.php?id=43073
See http://www.yessum.org/gdbug2/ for font and samples. This bug
appears to be in 5.1.6, and has since gotten worse in the latest svn.
Also, in 5.3.3-dev, the text doesn't seem to even be on the same
baseline on many of the angles.
Reproduce code:
---
?php
$font = './cour.ttf'; // Courier New
$im = imagecreatetruecolor(600, 600);
imagefill($im, 0, 0, imagecolorallocate($im, 224, 224, 224));
$black = imagecolorallocate($im, 0, 0, 0);
$red = imagecolorallocate($im, 255, 0, 0);
$angle = 0;
do {
$bbox = imagettftext($im, 16, $angle, 299, 299, $black, $font,
'The quick brown fox');
imagepolygon($im, $bbox, 4, $red);
$angle += 45;
} while ($angle 360);
header('content-type: image/png');
imagepng($im);
Expected result:
The bounding box should be a bounding box
Actual result:
--
The string is not contained in the bounding box.

#50960 [Com]: createimagefromwbmp fails to process some .bmp files (mime type: x-ms-bmp)

See comments at http://php.net/manual/en/function.imagecreate.php for an imagecreatefrombmp() function.
