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.

***** failures from 'make test' of 5.2.12 ***** these types of problems keep recurring (since 2001) so it seems that svn changes sometimes never make it to a stable release or there is no co-ordination with gd developers to prevent them from popping up again. i am normally happy with the centos lag away from fresh releases, but i need at least 5.2.12 for nginx and that is why i am trying to compile from source. 1.) 'Bug #43073/#48732 (TrueType bounding box is wrong for angle<>0) [ext/gd/tests/bug43073.phpt]'; 2.) 'Bug #48801/#48732 (Problem with imagettfbbox) [ext/gd/tests/bug48801.phpt]'; also (maybe) 3.)
