PDF Watermark resize

[failsafe]

Hello,

I have a watermark that I would like to put into my pdf. The watermark is a .bmp image, and is 2290 x 3026.  I am having a lot of trouble trying to resize this picture to fit the page, does anyone have any suggestions?

Document document = new Document();
                PdfWriter.getInstance(document, new FileOutputStream("result.pdf"));
                document.open();

                document.add(new Paragraph("hello"));
                document.close();
                PdfReader reader = new PdfReader("result.pdf");
                int number_of_pages = reader.getNumberOfPages();
                PdfStamper pdfStamper = new PdfStamper(reader, new FileOutputStream("result_watermark.pdf"));
                // Get the PdfContentByte type by pdfStamper.
                Image watermark_image = Image.getInstance("abstract(0307).bmp");
                int i = 0;
                watermark_image.setAbsolutePosition(0, 0);
                watermark_image.scaleAbsoluteWidth(626);
                watermark_image.scaleAbsoluteHeight(900);
                PdfContentByte add_watermark;
                while (i < number_of_pages) {
                        i++;
                        add_watermark = pdfStamper.getUnderContent(i);
                        add_watermark.addImage(watermark_image);
                       
                }
                pdfStamper.close();

In your code, I don't see you asking the reader for the page size, nor
for the origin of the page. Get the pagesize and use the scaleToFit()
method instead of the scaleAbsolute() methods. Don't forget to define
the offset of the image based on the origin of the coordinate system,
otherwise you risk adding the watermark outside the visible area of the
page.
