Note Submitter: ynblpb at thaos dot org ---- Note from 23-Sep-2009 09:13 has an error. When we rotate image to 270 degrees it have black line on top. Correct version: function rotateImage($img, $rotation) { $width = imagesx($img); $height = imagesy($img); switch($rotation) { case 90: $newimg= @imagecreatetruecolor($height , $width );break; case 180: $newimg= @imagecreatetruecolor($width , $height );break; case 270: $newimg= @imagecreatetruecolor($height , $width );break; case 0: return $img;break; case 360: return $img;break; } if($newimg) { for($i = 0;$i < $width ; $i++) { for($j = 0;$j < $height ; $j++) { $reference = imagecolorat($img,$i,$j); switch($rotation) { case 90: if(!@imagesetpixel($newimg, ($height - 1) - $j, $i, $reference )){return false;}break; case 180: if(!@imagesetpixel($newimg, $width - $i, ($height - 1) - $j, $reference )){return false;}break; case 270: if(!@imagesetpixel($newimg, $j, $width - $i - 1, $reference )){return false;}break; } } } return $newimg; } return false; }
