iText is a Java library originally created by Bruno Lowagie which allows to create PDF, read PDF and manipulate them. The following tutorial will show how to create PDF files with iText. This tutorial assumes that you have basis Java and Eclipse knowledge. iText has a hierarchical structure.
I think you are looking for water marking the pages in a PDF file.. check the below code. You could also use the Watermarker class.
PdfReader reader = new PdfReader("text.pdf");
int n = reader.getNumberOfPages();
// Create a stamper that will copy the document to a new file
PdfStamper stamp = new PdfStamper(reader,
new FileOutputStream("text1.pdf"));
int i = 1;
PdfContentByte under;
PdfContentByte over;
Image img = Image.getInstance("watermark.jpg");
BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA,
BaseFont.WINANSI, BaseFont.EMBEDDED);
img.setAbsolutePosition(200, 400);
while (i < n)
{
// Watermark under the existing page
under = stamp.getUnderContent(i);
under.addImage(img);
// Text over the existing page
over = stamp.getOverContent(i);
over.beginText();
over.setFontAndSize(bf, 18);
over.showText("page " + i);
over.endText();
i++;
}
stamp.close();
