#22404 [Bgs]: imageCopyMergeGray does not work

ID: 22404 User updated by: arebroff at rogers dot com Reported By: arebroff at rogers dot com Status: Bogus Bug Type: GD related Operating System: Windows XP PHP Version: 4.3.1 New Comment: I changed my code but new one does not work at all! I have to mention that imageCopyMerge vs imageCopyMergeGray works good in same function. ----------------------------- $old=imagecreatefromjpeg("userspictures/2.jpg"); $new=imagecreatefromjpeg("userspictures/3.jpg"); imageCopyMergeGray($new, $old, 0, 0, 50, 50, 50, 50, 100); Header("Content-type: image/jpeg"); Imagejpeg($new); ----------------------------- Previous Comments: ------------------------------------------------------------------------ [2003-02-25 17:55:56] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The code does not work as expected due to the fact that both source & destination images are the same. This function will not work unless you are working with 2 seperate images (different content). When that is the case the function appears to work correctly. ------------------------------------------------------------------------ [2003-02-24 16:41:17] arebroff at rogers dot com This code outputs picture but it is not in grey palette and it does not depend on $transition. Why? How do I need transform it to get image in black-and-white? ----------------- $old=@imagecreatefromjpeg("userspictures/2.jpg"); $transition=0; imageCopyMergeGray($old, $old, 0, 0, 100, 200, 300, 400, $transition); Header("Content-type: image/jpeg"); Imagejpeg($old, '', 80); ----------------- Thanks for any help.
