Java Barcode Interleaved 2 of 5 Generator for Java

Interleaved 2 of 5 encodes any even number of numeric characters in the widths (either narrow or wide) of the bars and spaces of the bar code. Unlike Standard 2 of 5, which only encodes information in the width of the bars, Interleaved 2 of 5 encodes data in the width of both the bars and spaces. This allows Interleaved 2 of 5 to achieve a somewhat higher density.

The symbology is called "interleaved" because the first numeric data is encoded in the first 5 bars while the second numeric data is encoded in the first 5 spaces that separate the first 5 bars. Thus the first 5 bars and spaces actually encode two characters. This is also why the bar code can only encode an even number of data elements.

Sample of an Interleaved 2 of 5 Barcode

Interleaved 2 of 5 Barcode for Java supports:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

The following Java code illustrates how to create a Interleaved 2 of 5 barcode, and output to various formats.

1     Linear linear = new Linear(); 
2     linear.setType(Linear.INTERLEAVED25); 
3     linear.setData("0123456789012"); 
4     linear.renderBarcode("c:/barcode.gif"); 
    
5     BufferedImage bufferedImage = linear.renderBarcode();

6     byte[] barcodeBytes = linear.renderBarcodeToBytes();

7     Graphics2D g = ...
8     Rectangle2D rectangle = ... 
9     linear.renderBarcode(g, rectangle);

10    OutputStream outputStream = ...
11    linear.renderBarcode(outputStream);

There are two methods to create Interleaved 2 of 5 barcode images in your Java web applications.

The simplest way is to stream barcode image using our buildin barcode servlet application.

Download the Barcode for Java Trial Package, and unzip it.
Under java_barcode_trial package, copy barcode folder to your java servlet container like tomcat.
Restart tomcat. Now you have installed successfully.
To test your installation, open your web browser and navigate to:
http://YourDomain:Port/barcode/linear?Data=0123456789012&Type=INTERLEAVED25.
To create barcode image in your JSP or html page, you need pass the url to IMG tag src value. For example,
<img src="http://YourDomain:Port/barcode/linear?Data=0123456789012&Type=INTERLEAVED25" />
Using this method, it will not generate any barcode images in your server side.

The second method is to generate barcode images in your server side.

Create a barcode image in server side, like
Linear linear = new Linear();
linear.setData("0123456789012");
linear.setType(Linear.INTERLEAVED25);
linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/barcode-images/barcode.gif");
In your JSP or HTML page, you need use IMG tag to display generated image, like
<img src="http://YourDomain:Port/YourWebApp/barcode-images/barcode.gif" />
