两个问题，

如何将白色隐藏或设置为矩形框边框
如何将文字添加到矩形

    public void addLinkedtoTOC(String src, String dest,String IMG,int linkedPageNumber,int linkDisplayTOCPageNumber) throws IOException, DocumentException {
    PdfReader reader = new PdfReader(src);
    PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
    Rectangle linkLocation = new Rectangle(320, 695, 560, 741);

    linkLocation.setBorderColorLeft(BaseColor.WHITE);
    linkLocation.setBorderColorRight(BaseColor.RED);
    linkLocation.setBorderColorTop(BaseColor.RED);
    PdfDestination destination = new PdfDestination(PdfDestination.FIT);
    PdfAnnotation link = PdfAnnotation.createLink(stamper.getWriter(), linkLocation, PdfAnnotation.HIGHLIGHT_INVERT,linkedPageNumber, destination);
    stamper.addAnnotation(link, linkDisplayTOCPageNumber);
    stamper.close();
    reader.close();
}

Answer 1

你的第一个问题很简单。这是iText - How to stamp image on existing PDF and create an anchor

的副本

创建表示链接注释的PdfAnnotation对象时，默认情况下会定义边框。您可以在注释级别使用setBorder()方法删除此边框，如AddImageLink示例中所示：

link.setBorder(new PdfBorderArray(0, 0, 0));

之前你的第二个问题也得到了回答。例如，见：

我在AddLinkAnnotation5示例中结合了两者：

public void manipulatePdf(String src, String dest) throws IOException, DocumentException {
    PdfReader reader = new PdfReader(src);
    PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
    // Here we define the location:
    Rectangle linkLocation = new Rectangle(320, 695, 560, 741);
    // here we add the actual content at this location:
    ColumnText ct = new ColumnText(stamper.getOverContent(1));
    ct.setSimpleColumn(linkLocation);
    ct.addElement(new Paragraph("This is a link. Click it and you'll be forwarded to another page in this document."));
    ct.go();
    // now we create the link that will jump to a specific destination:
    PdfDestination destination = new PdfDestination(PdfDestination.FIT);
    PdfAnnotation link = PdfAnnotation.createLink(stamper.getWriter(),
            linkLocation, PdfAnnotation.HIGHLIGHT_INVERT,
            3, destination);
    // If you don't want a border, here's where you remove it:
    link.setBorder(new PdfBorderArray(0, 0, 0));
    // We add the link (that is the clickable area, not the text!)
    stamper.addAnnotation(link, 1);
    stamper.close();
    reader.close();
}

但是，还有另一种方法可以同时添加文本和链接注释。我在回答重复问题时解释了这一点：How to add overlay text with link annotations to existing pdf? 在这个答案中，我参考AddLinkAnnotation2示例，我们使用ColumnText添加内容，如上所述，但我们引入了可点击的Chunk：

Chunk chunk = new Chunk("The Best iText Questions on StackOverflow", bold);
chunk.setAnchor("http://developers.itextpdf.com/frequently-asked-developer-questions");

将chunk对象包裹在Paragraph内，使用Paragraph添加ColumnText并获得无边界链接。
