Dear thanhnv,

Thanks for your inquiry.
Please set the barcode unit as pixel by code, here is entire code for your reference.
Code: Select all
            BarcodeSettings settings = new BarcodeSettings();
            settings = new BarcodeSettings();
            string data = "B1TAITUE/NGUYEN 123456 BjGVBLCKE 0786 018Y000 0001 147>1181 7017BKL 0000000000029041000000000000";
            settings.Type = BarCodeType.Pdf417;
            //set the unit as pixel.
            settings.Unit = GraphicsUnit.Pixel;
            settings.Data = data;
            settings.Data2D = data;
            BarCodeGenerator generator = new BarCodeGenerator(settings);
            Image barcode = generator.GenerateImage();
            barcode.Save("PDF417.png", System.Drawing.Imaging.ImageFormat.Png);
            string[] datas;
            datas = Spire.Barcode.BarcodeScanner.Scan(@"PDF417.png");

If there still is issue, please provide us your sample code for investigation.
