IText:如何在pdf中添加空白页?

我有pdf文档,例如25页。 如何在第10页和第11页添加一个空白页面?

首先点击谷歌:

/* * This class is part of the book "iText in Action - 2nd Edition" * written by Bruno Lowagie (ISBN: 9781935182610) * For more info, go to: http://itextpdf.com/examples/ * This example only works with the AGPL version of iText. */ package part1.chapter05; import java.io.FileOutputStream; import java.io.IOException; import com.itextpdf.text.Document; import com.itextpdf.text.DocumentException; import com.itextpdf.text.Paragraph; import com.itextpdf.text.pdf.PdfWriter; public class NewPage { /** Path to the resulting PDF file. */ public static final String RESULT = "results/part1/chapter05/new_page.pdf"; /** * Main method creating the PDF. * @param args no arguments needed * @throws IOException * @throws DocumentException */ public static void main(String[] args) throws IOException, DocumentException { // step 1 Document document = new Document(); // step 2 PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(RESULT)); // step 3 document.open(); // step 4 document.add(new Paragraph("This page will NOT be followed by a blank page!")); document.newPage(); // we don't add anything to this page: newPage() will be ignored document.newPage(); document.add(new Paragraph("This page will be followed by a blank page!")); document.newPage(); writer.setPageEmpty(false); document.newPage(); document.add(new Paragraph("The previous page was a blank page!")); // step 5 document.close(); } } 

使用后, document.newPage(); ,如果您不添加任何内容,将被忽略。 所以,如果你需要空白页面,那么添加writer.setPageEmpty(false); 在调用newPage()

只需看看PdfWriter的以下方法:

http://api.itextpdf.com/itext/com/itextpdf/text/pdf/PdfWriter.html#setPageEmpty(boolean

应该这样工作:

 Document doc = new Document(); PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream("file.pdf")); pdfWriter.setPageEmpty(false); doc.newPage(); doc.close(); 

您告诉作者该页面不是空的,即使它是,因此将创建一个新页面。
