Barcode Data Matrix Introduction

Data Matrix code 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.

Java Data Matrix Generator - Valid Data Scope

Java 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.

1. How to generate 2d barcode Data Matrix in Java class? (Complete Java Data Matrix Generator Demo Source Code)

   // Create Java Data Matrix object 
   DataMatrix barcode = new DataMatrix(); 
   
   // Set Data Matrix data text to encode
   barcode.setData("DataMatrix-IN-JAVA"); 
   
   // Generate Data Matrix barcode & print into Graphics2D object
   barcode.drawBarcode("Java Graphics2D object"); 
   
   // Generate Data Matrix barcode & encode into GIF format
   barcode.drawBarcode("C://barcode-datamatrix.gif"); 
   
   // Generate Data Matrix barcode & encode into JPEG format
   barcode.drawBarcode("C://barcode-datamatrix.jpg"); 
   
   

   
   
   

2. How to generate & encode Data Matrix barcodes to EPS?

   // Create Java Data Matrix object 
   DataMatrix barcode = new DataMatrix(); 
   
   // Set Data Matrix data text to encode
   barcode.setData("Create Data Matrix in EPS"); 
   
   // Generate Data Matrix barcode & encode into EPS
   barcode.drawBarcode2EPS("C://barcode-datamatrix.eps"); 

   
   
   

3. How to create & encode Data Matrix image in html or jsp pages?

   
   
   
   • Under demo package, copy barcode folder and its contents to your tomcat.
     
     
   • Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=DataMatrixEncodingData&TYPE=datamatrix
     
     
   • To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
     For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=DataMatrixEncodingData&TYPE=datamatrix" />
     
     
   
   
   

4. How to create & print barcode Data Matrix image in Java Servlet class?

   import com.onbarcode.barcode.AbstractBarcode; 
   import com.onbarcode.barcode.DataMatrix; 
   import javax.servlet.http.HttpServlet; 
   import javax.servlet.http.HttpServletRequest; 
   import javax.servlet.http.HttpServletResponse; 
   import javax.servlet.ServletException; 
   import javax.servlet.ServletOutputStream; 
      
   public class BarcodeServlet extends HttpServlet 
   { 
       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
       { 
           try { 
               DataMatrix barcode = new DataMatrix(); 
               barcode.setData("Data Matrix"); 
                    
               ServletOutputStream servletoutputstream = response.getOutputStream(); 
                 
               response.setContentType("image/jpeg"); 
               response.setHeader("Pragma", "no-cache"); 
               response.setHeader("Cache-Control", "no-cache"); 
               response.setDateHeader("Expires", 0); 
              
               // Generate DataMatrix barcode & output to ServletOutputStream
               barcode.drawBarcode(servletoutputstream); 
         
           } catch (Exception e) { 
               throw new ServletException(e); 
           } 
       } 
   } 

   
   
   

5. How to generate GS1 compatible Data Matrix?

   
   
   
   1. You need set property fnc1Mode value to IBarcode.FNC1_ENABLE (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.
   
   
   

6. Data Matrix Reader Programming and Macro 05, Macro 06

   
   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".
