Answer 1

Here is an example of how to add repeating watermark as the background to an existing document:

pdfDocument = new PdfDocument(new PdfReader(inFileName), new PdfWriter(outFileName));

PdfPattern.Tiling tiling = new Tiling(new Rectangle(100, 50));
new Canvas(new PdfPatternCanvas(tiling, pdfDocument), pdfDocument, tiling.getBBox()).add(new Paragraph("TESTING")
        .setFontColor(ColorConstants.RED)
        .setRotationAngle(Math.PI / 10));

for (int i = 1; i <= pdfDocument.getNumberOfPages(); i++) {
    PdfPage page = pdfDocument.getPage(i);
    new PdfCanvas(page.newContentStreamBefore(), page.getResources(), pdfDocument)
            .saveState()
            .setFillColor(new PatternColor(tiling))
            .rectangle(page.getCropBox())
            .fill()
            .restoreState();
}

pdfDocument.close();

This is how the result look visually:
