note 97393 added to function.imagecopymerge

Here is a modified version of Sina's function with better comments, the redundant code removed and the minor error corrected (inversion of opacity): <?php //PNG alpha channel support for imagecopymerge() //Works because imagecopy() supports 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 superimposes the source image onto it $portion = imagecreatetruecolor($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, $src_h); //Then superimposes this on the original image, using the defined transparency imagecopymerge($dst_im, $portion, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h, $pct); } ---- Server IP: 69.147.83.197 Probable Submitter: 92.24.63.8 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopymerge.php Edit -- https://master.php.net/note/edit/97393 Del: integrated -- https://master.php.net/note/delete/97393/integrated Del: useless -- https://master.php.net/note/delete/97393/useless Del: bad code -- https://master.php.net/note/delete/97393/bad+code Del: spam -- https://master.php.net/note/delete/97393/spam Del: non-english -- https://master.php.net/note/delete/97393/non-english Del: in docs -- https://master.php.net/note/delete/97393/in+docs Del: other reasons-- https://master.php.net/note/delete/97393 Reject -- https://master.php.net/note/reject/97393 Search -- https://master.php.net/manage/user-notes.php
