iTextSharper を使用してフッター付きの PDF を作成しようとしています。ほとんどの場合、これは正常に機能しています。各ページにフッターを追加したい。
私のコードはフッターを正しく追加しますが、画像でわかるように、テキストは PDF のコンテンツと重なっています。
コントローラーのアクション:

Order order = db.Orders.Where(x => x.ID == id).SingleOrDefault();
return new HFPdfResult(order, "OrderPDF");

ドキュメントのサイズの設定に関するSOの投稿を見ましたが、そうしましたが、うまくいかないようです:
var document = new Document(PageSize.A4, 36, 36, 36, 120);
下側に 120 ユーザー ユニットのマージンを与え、110 しか使用しないのに、なぜまだ重複しているのですか?
どんな助けでも大歓迎です。
