Note Submitter: Ralph Voigt, php --at -- drakedata.com ---- 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); } ?>
