How to insert a barcode into the lower continuum

I have a barcode creation code and the footer

            BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code128, "1234567890");

            Stream ms = new MemoryStream();
             generator.Save(ms, BarCodeImageFormat.Png);

            Aspose.Words.Document doc = new Aspose.Words.Document();

            DocumentBuilder builder = new DocumentBuilder(doc);

            builder.InsertImage(ms,
                RelativeHorizontalPosition.Margin,
                0,
                RelativeVerticalPosition.Margin,
                400,
                200,
                100,
                WrapType.Square);

There are two questions

1. How to create a right footer, now it is being created on the left
   2)How to insert a barcode into the footer

Now the barcode is inserted in an arbitrary place.I use aspose.words.

>Solution :

You can use DocumentBuilder.MoveToHeaderFooter to move cursor into the footer and then use ParagraphAlignment.Right to place barcode at right. See the following code:

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code128, "1234567890");
Stream ms = new MemoryStream();
generator.Save(ms, BarCodeImageFormat.Png);

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Move DocumentBuilder into the footer.
builder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
builder.ParagraphFormat.Alignment = ParagraphAlignment.Right;
builder.InsertImage(ms);

doc.Save(@"C:\Temp\out.docx");
