{

//Create a Word document
Document doc = new Document();
Section section = doc.AddSection();
Paragraph paragraph = section.AddParagraph();

//Append a Textbox to paragraph
TextBox tb = paragraph.AppendTextBox(120, 200);

//Set the position of Textbox
tb.Format.HorizontalOrigin = HorizontalOrigin.Page;
tb.Format.HorizontalPosition = 50;
tb.Format.VerticalOrigin = VerticalOrigin.Page;
tb.Format.VerticalPosition = 50;

//Set the fill effect of Textbox as picture
tb.Format.FillEfects.Type = BackgroundType.Picture;

//Fill the Textbox with a picture
tb.Format.FillEfects.Picture = Image.FromFile("Background.jpg");

//Save to file
doc.SaveToFile("InsertBackgroundImage.docx", FileFormat.Docx2013);
