***** 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.) 'Test imagecolorallocate() function : usage variations -
passing different data types to fourth argument
[ext/gd/tests/imagecolorallocate_variation4.phpt]'

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
-------------------------------
GD Version: bundled (2.0.34 compatible)
Freetype Version: 2.2.1
./configure --with-apxs2=/home/user/bin/httpd/bin/apxs
--prefix=/home/user/bin/php --with-pdo-mysql --with-zlib --with-gd
--with-gettext --with-freetype-dir --enable-gd-native-ttf
PHP 5.1.6 from centos rpms
--------------------------
GD Version: bundled (2.0.28 compatible)
FreeType Version 2.2.1
------------------------------------------------------------------------

Which GD library do you use? Bundled?

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.
