Hi, How can I use image as watermark with Aspose.Word for .NET? I found example for text watermark, but not image. MSWord 2010 is able to do that, so I beleive it is technically possible.

Thank you

Document doc = new Document(MyDir + "in.docx");

public static void InsertWatermarkImageAtEachPage(Document doc, string watermarkImagePath)

{

DocumentBuilder builder = new DocumentBuilder(doc);

PageSetup ps = builder.PageSetup;

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);

LayoutCollector collector = new LayoutCollector(doc);

Paragraph anchorPara = null;

int pageIndex = 0;

foreach (Paragraph para in paragraphs)

{

if (collector.GetStartPageIndex(para) == pageIndex)

{

anchorPara = para;

Shape watermark = new Shape(doc, Aspose.Words.Drawing.ShapeType.Image);

watermark.ImageData.SetImage(watermarkImagePath);

watermark.Width = 300;

watermark.Height = 300;

watermark.Left = 0;
