You can use LEADTOOLS Barcode Pro SDK technology in your application. https://www.leadtools.com/sdk/barcode The Barcode Pro SDK allows you to not only read barcodes but also write supported barcodes to an image or document. Here is some sample code: using (RasterCodecs _codecs = new RasterCodecs()) using (RasterImage _image = _codecs.Load(fileName, 1)) { BarcodeEngine bcEngine = new BarcodeEngine(); // Read Barcode BarcodeData data = bcEngine.Reader.ReadBarcode(barcodeImage, LeadRect.Empty, BarcodeSymbology.Unknown); if (data != null ) { Console.WriteLine( "Barcode Found" ); Console.WriteLine($ "Value: {data.Value}
" + $ "Symbology: {data.Symbology}
" + $ "Bounds: {data.Bounds}" ); Console.WriteLine( "=====================================" ); } // Write Barcode BarcodeEngine engine = new BarcodeEngine(); // Use can use the writer now, for example, write a UPCA barcode to an image: BarcodeData data = new BarcodeData(BarcodeSymbology.UPCA, "01234567890" ); data.Bounds = new LeadRect(0, 0, 400, 200); engine.Writer.WriteBarcode(_image, data, null ); }
