.NET Barcode Data Matrix Generator Introduction
Top
Generating Barcode Data Matrix in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing Data Matrix and other 30+ linear & 2D bar codes for C#, VB.NET & ASP.NET applications.
OnBarcode develops several .NET Barcode Generation components for different .NET development environments:

.NET Data Matrix Generator - Barcode Data Matrix Introduction

Data Matrix, also known as Data Matrix ECC200, is a two-dimensional matrix barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.

.NET Data Matrix Generation - Data Matrix Valid Data Scope

.NET Data Matrix Generator encodes:
  • all 128 characters of ASCII.
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII

   datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Png
   datamatrix.drawBarcode("C://vbnet-datamatrix.png")
	        
   ' Print Data Matrix to vb.net Bitmap object
   Dim datamatrixBitmap As Bitmap
   datamatrixBitmap = datamatrix.drawBarcode()
How to Create & Draw Data Matrix Image in ASP.NET aspx or Html Pages Without ASP.NET Barcode Controller?
Top
  • Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  • Restart IIS, navigate to http://YourDomain:Port/barcode/datamatrix.aspx?DATA=0123456789.
  • To create barcode Data Matrix image in html or aspx pages, you can insert a image tag (img) into your page.
    For example, <img src="http://YourDomain:Port/barcode/datamatrix.aspx?DATA=0123456789"/>
How to Create & Encode Barcode Data Matrix to Image File (GIF, JPEG, PNG, BMP)?

How to Generate GS1 Compatible Data Matrix?
Top
  1. You need set property FNC1 value to FNC1.FNC1_1ST_POS (1), to indicate that the generated data matrix is GS1 compatible.
  2. You can use 2 methods to input GS1 AI elements.
    1. Parenthesis: to use parenthesis to indicate an AI code. Eg. (01)12345.
    2. Escape Tilde: to use ~ai* to indicate an AI while * is digit number of the AI (from 2 ~ 7). Eg. ~ai20112345 same as (01)12345.
  • To use escape tilde, you need set processTilde property to true.
  • You can not use parenthesis character in the data message, except, user enables ProcessTilde flag and use ~040 and ~041 to replace '(' and ')'. Parenthesis must in pair, otherwise, the output would be incorrect.
Data Matrix Reader Programming and Macro 05, Macro 06
Top
To encode Data Matrix reader programming, macro 05 and macro 06, you need set ProcesTilde property to true, and add one of the following message to the beginning of the encoding Data Matrix data.
  1. ~rp: Reader Programming (for ASCII mode and Auto mode only)
    2. This should be located at the beginning of the encoding data, e.g. data = "~rpABCD1234".
  2. ~m5: 05 Macro (for ASCII mode and Auto mode only)
    3. This should be located at the beginning of the encoding data, e.g. data = "~m5ABCD1234".
  3. ~m6: 06 Macro (for ASCII mode and Auto mode only)
    4. This should be located at the beginning of the encoding data, e.g. data = "~m6ABCD1234".
In Visual Studio C# & VB.NET, How to Draw Barcode Data Matrix to .NET Graphics, Stream & Bitmap Objects?
Top
To draw & print barcode Data Matrix to C# objects:
   public void drawBarcode(Graphics graphics);

   public void drawBarcode(string filename);

   public Bitmap drawBarcode();

   public void drawBarcode(Stream fileStream);
This should be located at the beginning of the encoding data, e.g. data = "~m6ABCD1234".
   Public Sub drawBarcode(ByRef graphics As Graphics)

   Public Sub drawBarcode(ByVal filename As String)

   Public Function drawBarcode() As Bitmap

   Public Sub drawBarcode(ByRef fileStream As Stream)
