MH commented on PDFBOX-1176:
----------------------------

Well, it would be at least a big step forward if adding a watermark text would work. I tried with PDPageContentStream.drawString() to get at least some kind of workaround. (The examples I have found to add an Image via PDFContent.addImage() is no option for us.) But the first problem is, that this text overlaps the content and the text is always in black - even though I set cs.setStrokeingColor(Color.RED). My code:

---------------------------------------------------------------
final PDPageContentStream cs = new PDPageContentStream(doc, page, true, false, true); //4th parameter = resetContext
try {

    //simple text above the page:
    cs.beginText();
    cs.setStrokingColor(fontColor); //doesn't work
    cs.setFont(font, fontSize);
    cs.moveTo(10, 10);
    //cs.moveTextPositionByAmount(10, 10);
    //cs.setTextTranslation((pageSize.getWidth() / 2.0) - (stringWidth / 2.0), (pageSize.getHeight() / 2.0) - (fontSize / 2.0));
    cs.setTextRotation((double) 0.2, (pageSize.getWidth() / 2.0) - (stringWidth / 2.0), (pageSize.getHeight() / 2.0) - (fontSize / 2.0));
    //cs.setTextScaling(10.0, 10.0, (pageSize.getWidth() / 2.0) - (stringWidth / 2.0), (pageSize.getHeight() / 2.0) - (fontSize / 2.0));
    cs.setStrokingColor(Color.BLUE); //doesn't work
    cs.drawString(text);
    cs.endText();
} finally {
    if (cs != null) {
        cs.close();
    }
}

> I am checking if watermarks can  be added to a PDF doc and the same way can be removed, so far I could not find any option to do that with PDFBox; It will be better if we have an option to add and remove watermak to a PDF.
