Code-11 Barcode Introduction
Code-11 is also known as USD-8, was developed as a high-density numeric-only symbology.
It is used primarily in labeling telecommunications equipment. The symbology is discrete and is able to encode the numbers 0 through 9, the dash symbol (-), and start/stop characters.
Code 11 is not terribly secure in that printing imperfections can quite easily convert one character into another valid character. Data integrity is obtained by using one, or sometimes two, check characters.

Sample of a Code 11 Barcode
Code-11 Encoding Data Scope
Code 11 Barcode for Java supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • - (Dash)
How to Generate Code-11 Barcode in Java Class?
The following Java code illustrates how to create a Code-11 barcode, and output to various formats.
1     Linear linear = new Linear(); 
2 linear.setType(Linear.CODE11);
3 linear.setData("1234567890");
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);
  • Create a Linear barcode object (line 1)
  • Set Linear object barcode type to Code-11 (line 2)
  • Set Code-11 barcode data to encode (line 3)
  • Encode generated Code-11 barcode into gif image file (line 4)
  • Generate Code-11 and output to BufferedImage object (line 5)
  • Generate Code-11 in bitmap and output to byte[] (line 6)
  • Generate Code-11 and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
  • Generate Code-11 and output to OutputStream (line 10-11)
How to Generate Code-11 Barcode Image in Java Web Applications?
There are two methods to create Code-11 barcode images in your Java web applications.
  1. 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=123456789&Type=CODE11
    • 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=123456789&Type=CODE11" />
      Using this method, it will not generate any barcode images in your server side.
  2. 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("123456789");
      linear.setType(Linear.CODE11);
      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" />

Code-11 Barcode Property Settings
  1. Set the type property to Linear.CODE11
    Servlet URL Parameter: "Type". Value: 1. Sample: &Type=1.
  2. Set the data property with the value to encode.
    Type is String.
    Servlet URL Parameter: Data.
    • Valid Data Scope:
      • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
      • - (Dash)
    • Sample: "1234567890-12".
  3. addCheckSum property is not applied here.
    Barcode Library will automatically add one checksum character for data length from 1 to 10, otherwise two characters.
  4. Barcode image size settings.
    • Set property uom (Unit of Measure) for properties X, Y, leftMargin, rightMargin, topMargin and bottomMargin.
      Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
      Servlet URL Parameter: "UOM". Value: 0 (pixel), 1 (cm), 2 (inch). Sample: &UOM=0
    • Set the X (for barcode module width) and Y (for barcode module height) properties.
      Both types are float. Default X is 3. Y is 75.
      Servlet URL Parameter: "X", "Y". Sample: &X=3&Y=75
    • Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
      Default values are 0 for all 4 margin settings.
      Servlet URL Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin". Sample: &LeftMargin=0
    • Set the resolution property (Value is expressed in DPI - Dots per inch).
      Default is 72 dpi.
      Servlet URL Parameter: "Resolution". Sample: &Resolution=72
  5. Setting up text style in barcode image.
    • Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
      Default is true.
      Servlet URL Parameter: "ShowText". Value: "t" (true), "f" (false). Sample: &ShowText=t
    • Set the textFont property. The font used to display text in barcode image.
      Default is new Font("Arial", Font.PLAIN, 11).
      Servlet URL Parameter: "TextFont". Value format: [font name]|[font style]|[font size]. Sample Values: &TextFont=Arial|Bold|12
  6. With rotate property, you can display barcode horizontally or vertically.
    Default value is 0.
    Servlet URL Parameter: "Rotate". Sample: &Rotate=0.
    Value can be:
    • 0 (Linear.ANGLE_0),
    • 1 (Linear.ANGLE_90),
    • 2 (Linear.ANGLE_180),
    • 3 (Linear.ANGLE_270)
