You can use the LEADTOOLS Barcode Pro SDK in your application https://www.leadtools.com/sdk/products/barcode-pro You can utilize the BarcodeWriter class to write information to a QR barcode and add that barcode to an image. Here is some sample code: using (RasterCodecs _codecs = new RasterCodecs()) { using (RasterImage _image = _codecs.Load(fileName, 1)) { BarcodeEngine barcodeEngine = new BarcodeEngine(); QRBarcodeData data = new QRBarcodeData { SymbolModel = QRBarcodeSymbolModel.Model1AutoSize, Symbology = BarcodeSymbology.QR, Value = "QR Data Value" , Bounds = new LeadRect(10, 250, _image.ImageWidth, _image.ImageHeight) }; QRBarcodeWriteOptions options = new QRBarcodeWriteOptions { GroupNumber = 0, GroupTotal = 0, XModule = 30, ECCLevel = QRBarcodeECCLevel.LevelL, HorizontalAlignment = BarcodeAlignment.Near, VerticalAlignment = BarcodeAlignment.Near }; barcodeEngine.Writer.WriteBarcode(_image, data, options); _codecs.Save(image, @ "C:\Temp\barcode.bmp" , RasterImageFormat.Bmp, 0); } }
