IText学习手册——使用Chunk实现导航

Chunk对象的3个方法：

1.setLocalDestination();定义导航点

2.setLocalGoto();跳转到导航点

3.setRemoteGoto();跳转到外部网页

/// <summary>
        /// 使用Chunk实现导航
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button23_Click(object sender, EventArgs e)
        {
            Document doc = new Document();
            PdfWriter.GetInstance(doc, File.Open(path, FileMode.Create));
            doc.Open();

            Chunk top = new Chunk("This is top");
            top.SetLocalDestination("Top");
            Paragraph topParagraph = new Paragraph(top);
            doc.Add(topParagraph);

            for (var i = 0; i < 100; i++)
            {
                doc.Add(new Paragraph("This is " + (i + 1) + "line"));
            }

            Chunk goTop = new Chunk("Go to top");
            goTop.SetLocalGoto("Top");
            Paragraph bottomParagraph = new Paragraph(goTop);
            doc.Add(bottomParagraph);

            doc.Close();
        }
