Hey! Nasıl yeniden boyutlandırmak yok / onlar 350x100 üzerinde iseniz aşağı 350x100 benim yükleme komut dosyası ile yüklenen alır görüntülerin downscale?

Benim komut:

$allowed_filetypes = array('.png','.PNG');
$filename = $_FILES['strUpload']['name']; 
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); 
if(in_array($ext,$allowed_filetypes)) 
{
    list($width, $height, $type, $attr) = getimagesize($_FILES['strUpload']['tmp_name']);
    if ($width > 350 || $height > 100) 
    {
        echo "That file dimensions are not allowed. Only 350x100 is allowed";
        exit();
    } 

    if ($_FILES['strUpload']['size'] > 2097152 )
    {
        echo "ERROR: Large File Size. Only less than 2mb accepted";
        exit();
    }

    $imagename = uniqid('ff') . ".png";
    move_uploaded_file ( $_FILES['strUpload']['tmp_name'], $imagename );

    print ( "<script type=\"text/javascript\">" );
    if(file_exists($imagename) && $_FILES['strUpload']['name'] != '')
    {
        print ( "self.opener.SetImageFile(\"" . $imagename . "\");" );
        echo "\n";
        print ( "self.opener.setInputFile(\"" . $imagename . "\");" );
    }
    echo "\n";
    print ( "window.close();" );
    echo "\n";
    print ( "</script>" );

    $open = new dbconnect();
    $open->callDB("localhost","pema2201_william","lindberg","pema2201_siggen");

    $ip = $_SERVER['REMOTE_ADDR'];
    $dattum = date('Y-m-d H:i:s', time());

    mysql_query("INSERT INTO piclist (ip,pic,datum) VALUES('$ip','$imagename','$dattum')") or die(mysql_error());

} 
else 
{
    echo "WRONG FILE TYPE ONLY PNG ALLOWED"
}
