What Is A PDF-417 Barcode
PDF417, also named Portable Data File 417, PDF 417, PDF417 Truncated, is a stacked bi-dimensional barcode symbol used mainly in transport, inventory management and identification cards.
- All 128 characters of ASCII
- Extended ASCII. Values 128-255 in accordance with ISO 8859-1.
Encode Non-printable Chars in PDF-417
- Set TildeEnabled to true
- Use '~ddd' for non-printable chars. For example, ASCII char [GS] is non-printable, and its decimal value is 29. In barcode data, you need use ~029 for char [GS].
Encode byte[] in PDF-417 Barcode
The following C# source codes demo how to encode byte[] object in PDF-417
// Byte array to encode
byte[] dataBytes = new byte[] { 0x41, 0x42, 0x43, 0x44, 0x45 };
// Convert byte array to the input (property CodeToEncode)
String inputMsg = "";
foreach (byte b in dataBytes)
inputMsg += "~" + b.ToString().PadLeft(3, '0');
// Create barcode
BarCode barcode = new BarCode();
barcode.Symbology = Symbology.PDF417;
barcode.PDF417DataMode = PDF417DataMode.Byte;
// enable '~' in the input message
barcode.TildeEnabled = true;
barcode.CodeToEncode = inputMsg;
// set module size
barcode.BarcodeUnit = BarcodeUnit.Pixel;
barcode.X = 3;
barcode.PDF417XtoYRatio = 0.6F;
barcode.PDF417ColumnCount = 5;
barcode.PDF417RowCount = 10;
barcode.generateBarcodeToBitmap().Save(@"C:\PDF417_Bytes.png");
Encode non-English text in PDF-417 Barcode
The following C# source codes demo how to encode non English text (such as Japanese text) in PDF-417
// Message in Japanese
String unicodeMsg = @"おはようございます";
// Convert Unicode string to data bytes
byte[] dataBytes = Encoding.Unicode.GetBytes(unicodeMsg);
// Convert byte array to the input (property CodeToEncode)
String inputMsg = "";
foreach (byte b in dataBytes)
inputMsg += "~" + b.ToString().PadLeft(3, '0');
// Create barcode
BarCode barcode = new BarCode();
barcode.Symbology = Symbology.PDF417;
barcode.PDF417DataMode = PDF417DataMode.Byte;
// enable '~' in the input message
barcode.TildeEnabled = true;
barcode.CodeToEncode = inputMsg;
// set module size
barcode.BarcodeUnit = BarcodeUnit.Pixel;
barcode.X = 3;
barcode.PDF417XtoYRatio = 0.6F;
barcode.PDF417ColumnCount = 5;
barcode.PDF417RowCount = 10;
barcode.generateBarcodeToBitmap().Save(@"C:\PDF417_Japanese.png");
Generate Barcode Image in Specified Width and Height
- Set property AutoSizeAdjust to true
- Set property DPI to be the same or higher as your printer's resolution
- Set property BarcodeUnit to inch or cm
- Set property BarCodeWidth and BarCodeHeight to your required image width and height
