From: sks76543210 at gmail dot com Operating system: CentOS 5 PHP version: 5.3SVN-2010-02-09 (snap) PHP Bug Type: GD related Bug description: imagettftext/imagettfbbox return wrong coordinates if angle != 0
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. -- Edit bug report at http://bugs.php.net/?id=50971&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50971&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50971&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50971&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50971&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50971&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50971&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50971&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50971&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50971&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50971&r=support Expected behavior: http://bugs.php.net/fix.php?id=50971&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50971&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50971&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50971&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50971&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50971&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50971&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50971&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50971&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50971&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50971&r=mysqlcfg
