note 95983 added to function.imagecopymerge

Sina's method is elegant but had a small bug as well as some redundant code. Here is a more concise version with better comments: <?php //PNG alpha channel support for imagecopymerge() //This works because imagecopy() supports alpha but not blending, while imagecopymerge() supports blending but not alpha function imagecopymerge_alpha($dst_im, $src_im, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct) { //Creates a portion of the destination image and overlays the source image (with alpha) $portion = imagecreatetruecolor($src_w, $src_h); imagecopy($portion, $dst_im, 0, 0, $dst_x, $dst_y, $src_w, $src_h); imagecopy($portion, $src_im, 0, 0, $src_x, $src_y, $src_w, $src_h); //Blends the portion with the original image imagecopymerge($dst_im, $portion, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 81.108.89.249 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopymerge.php Edit -- https://master.php.net/note/edit/95983 Del: integrated -- https://master.php.net/note/delete/95983/integrated Del: useless -- https://master.php.net/note/delete/95983/useless Del: bad code -- https://master.php.net/note/delete/95983/bad+code Del: spam -- https://master.php.net/note/delete/95983/spam Del: non-english -- https://master.php.net/note/delete/95983/non-english Del: in docs -- https://master.php.net/note/delete/95983/in+docs Del: other reasons-- https://master.php.net/note/delete/95983 Reject -- https://master.php.net/note/reject/95983 Search -- https://master.php.net/manage/user-notes.php
