1. Java Data Matrix Introduction
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.
DataMatrix is being used to encode product and serial number information on electrical rating plates; to mark of surgical instruments in Japan; to identify lenses, circuit boards, and other items during manufacturing.
Barcode Library supports all DataMatrix Formats and the data represented in the symbol can be compressed using one of following algorithms.
  • 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.

Sample of a DataMatrix Barcode
2. Java Data Matrix Encoding Data Scope
Data Matrix Barcode for Java supports:
  • all 128 characters of ASCII
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.
3. How to Generate Barcode Data Matrix Image in Standalone Java Applications?

The following code illustrates how to create a barcode in a Java class

1            DataMatrix barcode = new DataMatrix(); 
2            barcode.setData("123456789"); 
4            barcode.renderBarcode("c:/datamatrix.gif");

  • Create a DataMatrix object (line 1)
  • set DataMatrix object properties (line 2)
  • save into gif file (line 4)

4. How to Generate Barcode Data Matrix Image in Web Applications?

There are two ways to create barcode images in your Java web applications.

  1. This is the simplest way to stream barcode image using our provided barcode servlet classes.

    And it will not save barcode images in your server side.

    • Under demo package, copy barcode folder to your java servlet container like tomcat.

    • To test your installation, goto http://YourDomain:Port/barcode/datamatrix?Data=123456789

    • To create barcode image in your JSP or html page, you can pass the url to IMG tag src value. For example, <img src="http://YourDomain:Port/barcode/datamatrix?Data=123456789" />

  2. The second method is similar with the way to generate barcode in Java applications.

    • Create a barcode image in server side 

      1            DataMatrix barcode = new DataMatrix(); 
2            barcode.setData("123456789"); 
4            barcode.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/bimages/datamatrix.gif");

    • In your JSP page, you can using IMG tag to display generated image, like <img src="http://YourDomain:Port/YourWebApp/bimages/datamatrix.gif" />

5. How to Generate Barcode Data Matrix Image in JasperReports?

The following jasper xml content illustrates how to insert a barcode into JasperReports

<import value="com.barcodelib.barcode.BarcodeJasperFactory"/>

Import class BarcodeJasperFactory to report. 

<image scaleImage="Clip" hAlign="Center"> 
    <reportElement x="50" y="110" width="515" height="120"/> 
    <graphicElement/> 
    <imageExpression class="net.sf.jasperreports.engine.JRRenderable">
     <![CDATA[new com.barcodelib.barcode.BarcodeJasperRenderer(BarcodeJasperFactory.createDataMatrix("123456789", 0, 0))]]></imageExpression> 
</image>

Please go to class BarcodeJasperFactory in Java doc for all methods to create barcode.

Developers can also extend or modify BarcodeJasperFactory class to meet their own requirements. Complete BarcodeJasperFactory.java Source Code

7. How to Save Barcode Data Matrix Image?
Just call DataMatrix object method renderBarcode, e.g. barcode.renderBarcode("c:/datamatrix.gif");
8. Java Data Matrix Property Settings
  • Set the data property with the value to encode. Type is String.
    Servlet Parameter: "Data".
  • Set the dataMode property.
    Valid value is DataMatrix.MODE_AUTO (default), DataMatrix.MODE_ASCII, DataMatrix.MODE_C40,
    DataMatrix.MODE_TEXT, DataMatrix.MODE_X12, DataMatrix.MODE_EDIFACT, DataMatrix.MODE_BASE256.
    • Auto (0): Barcode library will decide the best data mode for you.

9. How to Set Generated Barcode Data Matrix Image Size?

To set barcode image width and height, there are two ways to do it.

1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values, barcode library will render the barcode image for you.

or

2) You can set moduleSize value (barcode module width and height value), barcode library will calculate the barcodeWidth and barcodeHeight values for you, and render the barcode image.
