Java Data Matrix Generator

Barcode DataMatrix Generation in Java Class, Jasper Reports, iReport, BIRT

Java Barcode offers the most affordable Java barcode generator for barcode Java professionals.

Java Data Matrix Introduction

Data Matrix is also known as Data Matrix, ECC200.

DataMatrix is a two-dimensional (2D) barcode symbology which can store from 1 to about 2,000 characters.
DataMatrix ECC200 version supports advanced encoding error checking and correction algorithms (reed-solomon). Those algorithms allow the recognition of barcodes that are up to 60% damaged.

Java DataMatrix Properties

Class Properties	HTTP Parameters	Default	Comments
data	data	""	Barcode value to encode
uom	uom	PIXEL	Unit of meature for all size related settings. 0: pixel; 1: cm; 2: inch. Default is pixel
moduleSize	module-size	3	Barcode module width of barcode module, default is 3 pixel
leftMargin	left-margin	0	Barcode image left margin
rightMargin	right-margin	0	Barcode image right margin
topMargin	top-margin	0	Barcode image top margin
bottomMargin	bottom-margin	0	Barcode image bottom margin
resolution	resolution	72	Barcode image resolution in dpi
rotate	rotate	0	Barcode rotate angle, valid values: 0, 90, 180, 270
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. ~NNN: is used to represent the ASCII character with the value of NNN. NNN is from 000 - 255.
dataMode	data-mode	0 (Auto)	Set the dataMode property. Valid value is 0 DataMatrix.MODE_AUTO (default), 1 DataMatrix.MODE_ASCII, 2 DataMatrix.MODE_C40, 3 DataMatrix.MODE_TEXT, 4 DataMatrix.MODE_X12, 5 DataMatrix.MODE_EDIFACT, 6 DataMatrix.MODE_BASE256. Auto (0): Barcode library will decide the best data mode for you. ASCII (1): it is used to encode data that mainly contains ASCII characters (0-127). This is the default encoding format by Barcode Library. C40 (2): it is used to encode data that mainly contains numeric and upper case characters. Text (3): it is used to encode data that mainly contains numeric and lower case characters. X12 (4):it is used to encode the standard ANSI X12 electronic data interchange characters. EDIFACT (5): it is used to encode 63 ASCII values (values from 32 to 94) plus an Unlatch character (binary 011111). Base256 (6): it is used to encode 8 bit values.
formatMode	format-mode	0	Default is DataMatrix.FORMAT_10X10. Specifies the Data Matrix Format to use on that symbology. Valid values see class DataMatrix.FORMAT_x;
fnc1Mode	fnc1-mode	0 (none)
applicationIndicator	ai	0
isStructuredAppend	structured-append	false	If true, then Structured Append is enabled.
symbolCount	symbol-count	1	Set the number of total symbols which make the sequence.
symbolIndex	symbol-index	1	Set the position of current symbol in the secuence (Start with 0).
fileID	file-id	0	Set the property to be identified to the same file.

Java Barcode Data Matrix Generator - Java Class Implementation

The following Java code illustrates how to generate a barcode in Java class:



22       private static void testLinear() throws Exception 
23       { 
24           Linear barcode = new Linear(); 
25    
26           // set barcode properties 
27           barcode.setType(Linear.CODE128); 
28           barcode.setData("1234567890"); 
29    
30           // draw and generate barcode to specified file 
31           barcode.draw("C:\\Code128.gif"); 
32       }

Java Barcode Data Matrix Generator - Java Servlet Implementation

The following Java code illustrates how to generate a barcode in Java Servlet class:

11   public class BarcodeServlet extends HttpServlet { 
12       public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException 
13       { 
14           try { 
15               Linear barcode = new Linear(); 
16    
17               // set barcode properties 
18               barcode.setType(Linear.CODE128); 
19               barcode.setData("1234567890"); 
20    
21               // draw and generate barcode to response's ServletOutputStream 
22               ServletOutputStream servletoutputstream = response.getOutputStream(); 
23    
24               barcode.draw(servletoutputstream); 
25    
26           } catch (Exception e) { 
27               throw new ServletException(e); 
28           } 
29       } 
30   }

Java Barcode Data Matrix Generator - HTTP Request Implementation

Install Java Barcode Generator Servlet application to Tomcat or JBoss, developers need copy the barcode folder to your Tomcat application folder, and restart the Tomcat.
After Tomcat restarted, open your browser and navigate to http://your_tomcat_url:port/barcode/linear?data=12345678&type=8
You can also insert barcodes in HTML or JSP pages.

Java Barcode Data Matrix Generator - java.awt.Image Object Implementation

The following Java source code shows how to generate a barcode in a java.awt.Image object:


21    
22       private static void testLinear() throws Exception 
23       { 
24           Linear barcode = new Linear(); 
25            
26           // set barcode properties 
27           barcode.setType(Linear.CODE128); 
28           barcode.setData("1234567890"); 
29            
30           // create image object 
31           java.awt.image.BufferedImage image = new java.awt.image.BufferedImage(300,300,java.awt.image.BufferedImage.TYPE_BYTE_INDEXED ); 
32           // get graphic context of image 
33           java.awt.Graphics2D imgGraphics = image.createGraphics(); 
34    
35           // draw barcode to specified location in Rectangle 
36           barcode.draw(imgGraphics, new java.awt.Rectangle(0, 0, 300, 300)); 
37       }
