Is there any function to process the page of word? I found the old ticket that mentioned the DocumentLayoutHelper, but I can’t find how to use.
for example, get the document build by page number, moveToPageNumer()??

I’d like insert img watermark and text watermark on every page, but i fount when I add the second watemark would be delete first one using word.getWatermark().setImage。
So my solutions the first image watermak, I user the builder insert image on every page, but not using header or footer, the document has own headers and footers

@GusGus You need to use LayoutCollector to get the page number. Following links can be usefull:

Normally, watermark is inserted into the documents header, which is under the main document’s body content. This is the same behavior as in MS Word when you insert a watermark.
Here is a sample code:

Document doc = new Document("input.docx");

for (Section sect : doc.getSections())
{
    Shape watermark = createWatermark(doc, sect);

    insertWatermarkIntoHeader(watermark, sect, HeaderFooterType.HEADER_PRIMARY);
    insertWatermarkIntoHeader(watermark, sect, HeaderFooterType.HEADER_FIRST);
    insertWatermarkIntoHeader(watermark, sect, HeaderFooterType.HEADER_EVEN);
}

doc.save("output.docx");


private static Shape createWatermark(Document doc, Section currentSection) throws Exception {
    PageSetup pageSetup = currentSection.getPageSetup();

    Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);
    watermark.setName("WaterMark");
    watermark.getTextPath().setText("In Front Watermark");
    watermark.getTextPath().setBold(true);
    watermark.getTextPath().setSize(100);
    watermark.getTextPath().setFontFamily("Arial");
    watermark.setWidth(500);
    watermark.setHeight(100);
    watermark.getFill().setForeColor(Color.LIGHT_GRAY);
    watermark.getFill().setTransparency(0.7);
    watermark.setStrokeColor(Color.LIGHT_GRAY);
    watermark.getStroke().setTransparency(0.7);
    watermark.setRotation(-45);
    watermark.setWrapType(WrapType.NONE);
    watermark.setBehindText(true);
    watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);
    watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);
    double left = pageSetup.getPageWidth() / 3 - pageSetup.getLeftMargin() - pageSetup.getRightMargin();
    watermark.setLeft(left);
    watermark.setTop(pageSetup.getPageHeight() / 2);

    return watermark;
}

@GusGus Here is the code:

private static void insertWatermarkIntoHeader(Document doc, Shape watemark, Section sect, int headerType) {
        HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);
        if (header == null) {
            header = new HeaderFooter(sect.getDocument(), headerType);
            sect.getHeadersFooters().add(header);
        }

        Paragraph headerPara = (Paragraph) header.getChild(NodeType.PARAGRAPH, 0, true);
        if (headerPara == null) {
            Paragraph watermarkPara = new Paragraph(doc);
            watermarkPara.appendChild(watemark);
            header.appendChild(watermarkPara.deepClone(true));
        } else {
            headerPara.appendChild(watemark);
        }
    }

@GusGus There are no automatically set widht and height values for text shapes. You need to set them. However, if you set only height, the width will be automatically scaled.
