#43010 [Ana->Csd]: imagefilledarc() incorrect fill for certain start/end angles

ID: 43010 Updated by: pajoye@php.net Reported By: johanp at aditus dot nu -Status: Analyzed +Status: Closed Bug Type: GD related Operating System: Linux PHP Version: 4.4.7 Assigned To: pajoye New Comment: This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. It is not broken in 5.2 _snapshot_ and as far as I remember, it should work as well in 5.2.4. By the way, this regression was introduced two releases ago and affects arcs with equivalent start and end angles and the start angle is different than zero. Fixed in CVS.

The fix for the regression was never made back to 4.4, I'll try to do this at the weekend if Pierre doesn't get around to it. ------------------------------------------------------------------------ [2007-10-20 09:35:09] johanp at aditus dot nu This is broken in 5.2.0 as well ------------------------------------------------------------------------ [2007-10-18 08:45:08] pajoye@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi ------------------------------------------------------------------------ [2007-10-17 22:02:36] johanp at aditus dot nu This is a regression in 4.4.7 since this is working in 4.4.6 ------------------------------------------------------------------------ [2007-10-17 21:49:38] johanp at aditus dot nu Description: ------------ In PHP 4.4.7 imagefilledarc() has a defect filling a full circle when the start angle is not =0 Reproduce code: --------------- <?php $im = imagecreatetruecolor (600, 400); $black = imagecolorallocate ($im, 0, 0, 0); $white = imagecolorallocate ($im, 255, 255, 255); // The following code should show two white circles.
