Data Matrix data encoding in C#

Encoding character set and Data Matrix barcode data mode

Data Matrix barcode supports encoding both full ASCII chars and extended ASCII chars

• Full ASCII (all 128 characters)
• Extended ASCII (ISO 8859-1 values 128-255)
• Other ISO character sets (e.g. Arabic, Cyrillic, Greek, Hebrew) may be supported when using the ECI protocol. View more details at How to encode international text in Data Matrix barcode using C#

Data Matrix data mode

To encode the above character sets, QR Code defines five encoding data modes.

• Auto: C# barcode library will automatically use the right Data Matrix data modes to encode data message.
• ASCII: Encode double digit numerics; ASCII values 0 - 127 and Extended ASCII values 128 - 255
• C40: Encode Upper-case alphanumeric; Lower case and special characters
• Text: Encode Lower-case alphanumeric; Upper case and special characters
• X12: Encode ANSI X12 EDI data set
• EDIFACT: Encode ASCII values 32 - 94
• Base 256: Encode All byte values 0 - 255

Data Matrix maximum data length

Depends on Data Matrix data mode used, Data Matrix maximum character length are

• alphanumeric data: 2,335 characters
• byte data: 1,555 characters
• numeric data: 3,116 digits

How to generate GS1 compatible Data Matrix barcodes using C#

GS1 Data Matrix barcode is using Data Matrix barcode to encode GS1 format data message.

To create valid GS1 Data Matrix using C# Data Matrix barcode generator library, you need apply the following options in class RasterEdge.XImage.BarcodeCreator.DataMatrix using C# code in your ASP.NET Core, MVC, Windows aspplications.

• FNC1: The value should be RasterEdge.XImage.BarcodeCreator.FNC1.FNC1_1ST_POS.
• DataMode: The value should be DataMatrixDataMode.Auto
• Data: Valid GS1 data message includes pairs of AI code and AI data. Using data matrix generator C# library, all AI codes should be surrounded by parentheses. For example: (11)010101(15)020202

            DataMatrix barcode = new DataMatrix();

            barcode.Data = "(10)ABC123(17)050101";

            barcode.DataMode = DataMatrixDataMode.Auto;

            barcode.FNC1 = FNC1.FNC1_1ST_POS;


            barcode.AutoResize = true;
            barcode.UOM = UnitOfMeasure.INCH;
            barcode.BarcodeWidth = 2F;
            barcode.BarcodeHeight = 2F;
            barcode.Resolution = 300;

            Bitmap datamatrixBitmap = barcode.ToImage();
            datamatrixBitmap.Save(
                @"W:\Projects\Test-Output\RasterEdge.com\NetCoreSDK\barcode-data-matrix-gs1-data.png");

How to generate Data Matrix barcode with international characters encoded using C#

It is really easy to generate Data Matrix with non-English characters encoded.

1. Convert characters to byte array using UTF8 encoding.
2. Generate Data Matrix with converted byte array using DataMatrixDataMode.Base256 data mode.

Following properties should be applied to encode international characters in Data Matrix using C#:

• ProcessTilde: Set to enable '~' in data message.
• DataMode:It should be DataMatrixDataMode.Base256
• Data: The international characters should be converted to byte array using UTF8 encoding.

            DataMatrix barcode = new DataMatrix();

            string message = "สวัสดี";
            byte[] bytes = Encoding.UTF8.GetBytes(message);
            StringBuilder messageInBytes = new StringBuilder();
            foreach (byte b in bytes)
                messageInBytes.Append("~" + b.ToString().PadLeft(3, '0'));

            barcode.Data = messageInBytes.ToString();
            barcode.ProcessTilde = true;
            barcode.DataMode = DataMatrixDataMode.Base256;

            //  Set barcode size to 2 inch x 2 inch
            barcode.AutoResize = true;
            barcode.UOM = UnitOfMeasure.INCH;
            barcode.BarcodeWidth = 2F;
            barcode.BarcodeHeight = 2F;
            //  Set image resolution to 300 dpi.
            barcode.Resolution = 300;

            //  Set all margins to 0
            barcode.LeftMargin = 0;
            barcode.RightMargin = 0;
            barcode.TopMargin = 0;
            barcode.BottomMargin = 0;

            Bitmap qrcodeBitmap = barcode.ToImage();
            qrcodeBitmap.Save(@"W:\Projects\Test-Output\RasterEdge.com\barcode-data-matrix-international-byte.png");
