note 101741 added to function.imagecopymerge

Thanks to Sina Salek for the simplified imagecopymerge_alpha function with support for alpha channel. However, there's a bug which causes it to work only for $src_x = $src_y = 0. Also, inverting opacity is not necessary. Here's the fixed version: <?php /** * PNG ALPHA CHANNEL SUPPORT for imagecopymerge(); * by Sina Salek * * Bugfix by Ralph Voigt **/ function imagecopymerge_alpha($dst_im, $src_im, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct){ // creating a cut resource $cut = imagecreatetruecolor($src_w, $src_h); // copying relevant section from background to the cut resource imagecopy($cut, $dst_im, 0, 0, $dst_x, $dst_y, $src_w, $src_h); // copying relevant section from watermark to the cut resource imagecopy($cut, $src_im, 0, 0, $src_x, $src_y, $src_w, $src_h); // insert cut resource to destination image imagecopymerge($dst_im, $cut, $dst_x, $dst_y, 0, 0, $src_w, $src_h, $pct); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 178.2.138.57 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopymerge.php Edit -- https://master.php.net/note/edit/101741 Del: integrated -- https://master.php.net/note/delete/101741/integrated Del: useless -- https://master.php.net/note/delete/101741/useless Del: bad code -- https://master.php.net/note/delete/101741/bad+code Del: spam -- https://master.php.net/note/delete/101741/spam Del: non-english -- https://master.php.net/note/delete/101741/non-english Del: in docs -- https://master.php.net/note/delete/101741/in+docs Del: other reasons-- https://master.php.net/note/delete/101741 Reject -- https://master.php.net/note/reject/101741 Search -- https://master.php.net/manage/user-notes.php
