Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.

 

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 barcode Data Matrix in Java class?

   // 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/datamatrix?DATA=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/datamatrix?DATA=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); 
           } 
       } 
   }

8. How to set generated barcode Data Matrix image width and height?

   1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values.
   
   or
   
   2) You can set X (bar module width) and Y (bar module height) values
   
   

 
Java Data Matrix Generator in Java Class: com.onbarcode.barcode.DataMatrix

Category	Class Properties	Servlet Properties	Default	Comments
Basic	data	DATA	""	value to encode
Data Matrix Special	processTilde	PROCESS-TILDE	false	Set the processTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is false. ~3: is used only at the very beginning of the symbol for the reader programming purpose. ~5: is used only at the very beginning of the symbol, the header [)> + ASCII 30 + ASCII 05 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards. ~6: is used only at the very beginning of the symbol, the header [)> + ASCII 30 + ASCII 06 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards. ~7NNNNNN: is used to specify the Extended Channel Interpretations and NNNNNN is a value between 000000 and 999999. ~NNN: is used to represent the ASCII character with the value of NNN. NNN is from 000 to 255
