note 75298 added to function.imagecreatetruecolor

If you want to create a *transparent* PNG image, where the background is fully transparent, and all draw operations happen on-top of this, then do the following: <?php $png = imagecreatetruecolor(800, 600); imagesavealpha($png, true); $trans_colour = imagecolorallocatealpha($png, 0, 0, 0, 127); imagefill($png, 0, 0, $trans_colour); $red = imagecolorallocate($png, 255, 0, 0); imagefilledellipse($png, 400, 300, 400, 300, $red); header("Content-type: image/png"); imagepng($png); ?> What you do is create a true colour image, make sure that the alpha save-state is on, then fill the image with a colour that has had its alpha level set to fully transparent (127). The resulting PNG from the code above will have a red circle on a fully transparent background (drag the image into Photoshop to see for yourself) ---- Server IP: 194.145.210.4 Probable Submitter: 88.96.15.166 ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatetruecolor.php Edit -- https://master.php.net/note/edit/75298 Del: integrated -- https://master.php.net/note/delete/75298/integrated Del: useless -- https://master.php.net/note/delete/75298/useless Del: bad code -- https://master.php.net/note/delete/75298/bad+code Del: spam -- https://master.php.net/note/delete/75298/spam Del: non-english -- https://master.php.net/note/delete/75298/non-english Del: in docs -- https://master.php.net/note/delete/75298/in+docs Del: other reasons-- https://master.php.net/note/delete/75298 Reject -- https://master.php.net/note/reject/75298 Search -- https://master.php.net/manage/user-notes.php
