.NET Data Matrix Generator - Barcode Data Matrix Introduction

Data Matrix 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.

Generating barcode Data Matrix in C# Class example (C# Data Matrix Generator Complete Demo Source Code)

	        DataMatrix datamatrix = new DataMatrix();
	        datamatrix.Data = "0123456789";
	        datamatrix.X = 3;
	        
	        // Generate Data Matrix and encode barcode to gif format
	        datamatrix.Format = ImageFormat.Gif;
	        datamatrix.drawBarcode("c#-datamatrix.gif");
	        
	        // Print Data Matrix to C# Bitmap object
	        Bitmap datamatrixBitmap = datamatrix.drawBarcode();

Generating barcode Data Matrix in VB.NET Class example (VB.NET Data Matrix Generator Complete Demo Source Code)

	        Dim datamatrix As OnBarcode.Barcode.DataMatrix
	        datamatrix = New OnBarcode.Barcode.DataMatrix()
	        datamatrix.Data = "0123456789"
	        datamatrix.X = 3
	        
	        // Generate Data Matrix and encode barcode to png format
	        datamatrix.Format = ImageFormat.Png
	        datamatrix.drawBarcode("vbnet-datamatrix.png")
	        
	        // Print Data Matrix to vb.net Bitmap object
	        Dim datamatrixBitmap As Bitmap
	        datamatrixBitmap = datamatrix.drawBarcode();

• 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" />
  
  

Creating barcode Data Matrix in C# Class example

	        DataMatrix datamatrix = new DataMatrix();
	        datamatrix.Data = "0123456789";
	        
	        // Create Data Matrix and encode barcode to Jpeg format
	        datamatrix.Format = ImageFormat.Jpeg;
	        datamatrix.drawBarcode("C://csharp-datamatrix.jpg");

Creating barcode Data Matrix in VB.NET Class example

	        Dim datamatrix As OnBarcode.Barcode.DataMatrix
	        datamatrix = New OnBarcode.Barcode.DataMatrix()
	        datamatrix.Data = "0123456789"
	        
	        // Create Data Matrix and encode barcode to Jpeg format
	        datamatrix.Format = ImageFormat.Jpeg
	        datamatrix.drawBarcode("C://vbnet-datamatrix.jpg")

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
      
      Note:
      
      1. To use escape tilde, you need set processTilde property to true.
      
      2. 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.

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)
   
   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)
   
   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)
   
   This should be located at the beginning of the encoding data, e.g. data = "~m6ABCD1234".

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);

To draw & print barcode Data Matrix to VB.NET objects:

	        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)
