note 92787 added to function.imagecopymerge

I've just checked PHP's issue tracker and a core developer says that this function was never meant to support alpha channel! and they refused to commit the provided patch! so ridicules Anyway i tried rodrigo's workaround and it worked quite well, thanks rodrigo for sharing it. I came up with another idea which is much faster than his solution, (it may need a little bit more memory) Hope it helps someone. You can find me here : you can find me here http://sina.salek.ws/en/contact <?php /** * PNG ALPHA CHANNEL SUPPORT for imagecopymerge(); * This is a function like imagecopymerge but it handle alpha channel well!!! **/ function imagecopymerge_alpha($dst_im, $src_im, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct){ $opacity=$pct; // getting the watermark width $w = imagesx($src_im); // getting the watermark height $h = imagesy($src_im); // creating a cut resource $cut = imagecreatetruecolor($src_w, $src_h); // copying that section of the background to the cut imagecopy($cut, $dst_im, 0, 0, $dst_x, $dst_y, $src_w, $src_h); // inverting the opacity $opacity = 100 - $opacity; // placing the watermark now imagecopy($cut, $src_im, 0, 0, $src_x, $src_y, $src_w, $src_h); imagecopymerge($dst_im, $cut, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $opacity); } ?> ---- Server IP: 79.132.192.3 Probable Submitter: 84.47.225.66 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopymerge.php Edit -- https://master.php.net/note/edit/92787 Del: integrated -- https://master.php.net/note/delete/92787/integrated Del: useless -- https://master.php.net/note/delete/92787/useless Del: bad code -- https://master.php.net/note/delete/92787/bad+code Del: spam -- https://master.php.net/note/delete/92787/spam Del: non-english -- https://master.php.net/note/delete/92787/non-english Del: in docs -- https://master.php.net/note/delete/92787/in+docs Del: other reasons-- https://master.php.net/note/delete/92787 Reject -- https://master.php.net/note/reject/92787 Search -- https://master.php.net/manage/user-notes.php
