Cảm ơn vì điều này. Nếu bạn không muốn giới hạn nó chỉ với A4, bạn có thể thêm document.setPageSize (reader.getPageSize (1)); – Dittimon
Khi tôi sử dụng phương pháp này, PDF xuất hiện tất cả không đúng giá trị. Vì vậy, tôi đã đi với câu trả lời của Mark Storer và sử dụng PdfStamper. –
Thao tác này hoạt động tốt, nhưng các trang có acrofields không được sao chép với chúng trong cb.addTemplate (trang, 0,0). Acrofields không có sẵn ở đầu ra pdf – Vicky
