Add an image to an existing PDF

Do you know the problem: You got a PDF document and want to add an image to a single page, but you have no printer/scanner.

Normally jPdf Tweak solves simple PDF problems, but it is not possible to add a simple image to a PDF file :( . It supports watermarks, but it is not supported to set the position or page.

I wrote some lines of code to solve my problem:

PdfReader pdr = new PdfReader("D:\\test.pdf");

PdfStamper pds = new PdfStamper(pdr, new FileOutputStream("D:\\test_image.pdf"));

PdfContentByte pcbPosition;

PdfGState pgsTransparency;

Image img;

for (int i = 1, anz = pdr.getNumberOfPages(); i <= anz; i++)
        //only first page
        if (i == 1)
                pcbPosition = pds.getOverContent(i);
                pgsTransparency = new PdfGState();
                pgsTransparency.setFillOpacity(100 / 100f);
                img = Image.getInstance(FileUtil.getContent("D:\\image.png"));
                //x: 0 = left
                //y: 0 = bottom
                img.setAbsolutePosition(500f, 250f);
                //70 is 100%
