I have written a small sample demo that shows how to use our Automated annotations along with our BarcodeEngine and BarcodeWriter classes to write barcodes to a AnnStampObject.

Here is a screenshot of what the demo looks like:

Here is the relevant code from the sample:

Code to write the barcode to an image:

Code:

RasterImage barcodeImage = RasterImage.Create(300, 300, 24, 150, RasterColor.White);

LogicalRectangle writebounds = LogicalRectangle.FromLTRB(0, 0, barcodeImage.ImageSize.Width, barcodeImage.ImageSize.Height, LogicalUnit.Pixel);
BarcodeEngine barcodeEngine = new BarcodeEngine();
QRBarcodeData qrData = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData;
qrData.Value = barcodestring;

QRBarcodeWriteOptions options = new QRBarcodeWriteOptions();
options.HorizontalAlignment = BarcodeAlignment.Center;
options.VerticalAlignment = BarcodeAlignment.Center;

barcodeEngine.Writer.CalculateBarcodeDataBounds(writebounds, barcodeImage.XResolution, barcodeImage.YResolution, qrData, options);
barcodeEngine.Writer.WriteBarcode(barcodeImage, qrData, options);

Code to add the Barcode Image to the stamp and the stamp to the Automation programmatically:

Code:

AnnStampObject stamp = new AnnStampObject();
stamp.Rect = LeadRectD.Create(200, 200, 600, 600);
stamp.Text = "";
stamp.Stroke.Stroke = AnnSolidColorBrush.Create("");

using (MemoryStream ms = new MemoryStream())
using (RasterCodecs codecs = new RasterCodecs())
{
     codecs.Save(barcodeImage, ms, RasterImageFormat.Png, 32);
     stamp.Picture = new AnnPicture(ms.ToArray());
}

annAutomation.Container.Children.Add(stamp);
annAutomation.InvalidateObject(stamp);
