note 109787 added to function.imagefilledrectangle

I wanted to clear an image, and set it to full transparent. imagefilledrectangle() seems to ignore alpha channel and alpha blending. Use imagefill() instead: <php $w = imagesx($final); $h = imagesy($final); $grande = imagecreatetruecolor($w, $h); // Alpha blending on to use channel alpha imagealphablending($grande, true); // Allocate a transparent color and fill the new image with it. // Without this the image will have a black background instead // of being transparent. $transparent = imagecolorallocatealpha($grande, 0, 0, 0, 127); // transparent alpha will be _ignored_: imagefilledrectangle($grande, 0, 0, $w, $h, $transparent); // ok, transparent will be used and set whole alpha channel to transparent: imagefill($grande, 0, 0, $transparent); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 78.224.184.168 ---- Manual Page -- http://www.php.net/manual/en/function.imagefilledrectangle.php Edit -- https://master.php.net/note/edit/109787 Del: integrated -- https://master.php.net/note/delete/109787/integrated Del: useless -- https://master.php.net/note/delete/109787/useless Del: bad code -- https://master.php.net/note/delete/109787/bad+code Del: spam -- https://master.php.net/note/delete/109787/spam Del: non-english -- https://master.php.net/note/delete/109787/non-english Del: in docs -- https://master.php.net/note/delete/109787/in+docs Del: other reasons-- https://master.php.net/note/delete/109787 Reject -- https://master.php.net/note/reject/109787 Search -- https://master.php.net/manage/user-notes.php
