Note Submitter: ewald at dutchvisual dot nl ---- This function will rotate the image. The image will be resampled completely. <?php 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, $i, ($height - 1) - $j, $reference )){return false;}break; case 270: if(!@imagesetpixel($newimg, $j, $width - $i, $reference )){return false;}break; } } } return $newimg; } return false; } ?> you can call it this way: <?php $img = rotateImage($imagetorotate,"degrees"); ?>
