How to Add Watermark to a MS Word Document inside Android Applications

This technical tip explains how to add a watermark to a document in Microsoft Word document inside Android Applications. Sometimes you need to insert a watermark into a Word document, for instance if you would like to print a draft document or mark it as confidential. In Microsoft Word, you can quickly insert a watermark using the Insert Watermark command. Not many people using this command realize that such “watermark” is just a shape with text inserted into a header or footer and positioned in the centre of the page. While Aspose.Words doesn't have a single insert watermark command like Microsoft Word, it is very easy to insert any shape or image into a header or footer and thus create a watermark of any imaginable type.

Paragraph watermarkPara = new Paragraph(doc); watermarkPara.appendChild(watermark); // Insert the watermark into all headers of each document section. for (Section sect : doc.getSections()) { // There could be up to three different headers in each section, since we want // the watermark to appear on all pages, insert into all headers. insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY); insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST); insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN); } } private static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception { HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType); if (header == null) { // There is no header of the specified type in the current section, create it. header = new HeaderFooter(sect.getDocument(), headerType); sect.getHeadersFooters().add(header); } // Insert a clone of the watermark into the header. header.appendChild(watermarkPara.deepClone(true)); } }
