Borders defined for `Rectangle` are rendered when you add a rectangle to the actual content. Annotations (such as a link annotation) aren't actual content. The `Rectangle` class is used for annotations to define the location, *not* to define the border. Borders for an annotation are defined at the level of the annotation. — Bruno Lowagie, Jan 02 '16 at 16:36
You question is very similar to [How to add overlay text with link annotations to existing pdf?](http://stackoverflow.com/questions/28554413/how-to-add-overlay-text-with-link-annotations-to-existing-pdf) — Bruno Lowagie, Jan 02 '16 at 16:43

Your first question is easy. It's a duplicate of iText - How to stamp image on existing PDF and create an anchor

When you create a PdfAnnotation object that represents a link annotation, a border is defined by default. You can remove this border using the setBorder() method at the level of the annotation as is done in the AddImageLink example:

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

Your second question has also been answered before. See for instance:

I have combined both in the AddLinkAnnotation5 example:

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();
}

However, there's also another way to add the text and the link annotation at the same time. That's explained in my answer to the duplicate question: How to add overlay text with link annotations to existing pdf? In this answer, I refer to the AddLinkAnnotation2 example, where we add the content using ColumnText as described above, but we introduce a clickable Chunk:

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

Wrap the chunk object inside a Paragraph, add the Paragraph using ColumnText and you have your borderless link.
