note 109432 added to function.imagerotate

After some INet searches and personal try-and-failures I succeed to rotate PNG images with preserving alpha channel transparency (semi transparency). <?php $filename = 'YourFile.png'; $rotang = 20; // Rotation angle $source = imagecreatefrompng($filename) or die('Error opening file '.$filename); imagealphablending($source, false); imagesavealpha($source, true); $rotation = imagerotate($source, $rotang, imageColorAllocateAlpha($source, 0, 0, 0, 127)); imagealphablending($rotation, false); imagesavealpha($rotation, true); header('Content-type: image/png'); imagepng($rotation); imagedestroy($source); imagedestroy($rotation); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 78.83.68.10 ---- Manual Page -- http://www.php.net/manual/en/function.imagerotate.php Edit -- https://master.php.net/note/edit/109432 Del: integrated -- https://master.php.net/note/delete/109432/integrated Del: useless -- https://master.php.net/note/delete/109432/useless Del: bad code -- https://master.php.net/note/delete/109432/bad+code Del: spam -- https://master.php.net/note/delete/109432/spam Del: non-english -- https://master.php.net/note/delete/109432/non-english Del: in docs -- https://master.php.net/note/delete/109432/in+docs Del: other reasons-- https://master.php.net/note/delete/109432 Reject -- https://master.php.net/note/reject/109432 Search -- https://master.php.net/manage/user-notes.php
