EAN-8 Barcode Introduction
EAN-8 is also known as European Article Number 8, EAN-8 Supplement 5/Five-digit Add-On, EAN-8 Supplement 2/Two-digit Add-On, EAN-8+5, EAN-8+2, EAN8, EAN8+5, EAN13+2, UPC-8, GTIN-8, GS1-8, EAN/UCC-8.
An EAN-8 is a barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced mainly to use on small packages where an EAN-13 barcode would be impractical; for example on cigarettes, pencils even though not used very common and chewing gum packets.
EAN-8 is a shortened version of the EAN-13 code. It includes a 2 or 3 digit country code, 4 or 5 data digits (depending on the length of the country code), and a checksum digit. The primary purpose of the EAN-8 is to be used on small packages, so the code must use as little space as possible.
EAN-8 codes are most common in the UK, and as such many UK-based companies use blocks of EAN-8 codes for own-brand products which are only sold in their stores. These are formatted as 1xxx xxxx.

Sample of an EAN-8 Barcode
EAN-8 Encoding Data Scope
EAN-8 Barcode for Java supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to Generate EAN-8 Barcode in Java Class?
The following Java code illustrates how to create a EAN-8 barcode, and output to various formats.
1     Linear linear = new Linear(); 
2 linear.setType(Linear.EAN8);
3 linear.setData("2012345");
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 EAN-8 (line 2)
  • Set EAN-8 barcode data to encode (line 3)
  • Encode generated EAN-8 barcode into gif image file (line 4)
  • Generate EAN-8 and output to BufferedImage object (line 5)
  • Generate EAN-8 in bitmap and output to byte[] (line 6)
  • Generate EAN-8 and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
  • Generate EAN-8 and output to OutputStream (line 10-11)
How to Generate EAN-8 Barcode Image in Java Web Applications?
There are two methods to create EAN-8 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:
    • 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=1234567&Type=EAN8" />
      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.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" />

Java EAN-8 Barcode Property Settings
  1. Set the type property to Linear.EAN8 or Linear.EAN8_2 or Linear.EAN8_5
    Servlet URL Parameter: "Type". Value: 7 (EAN8), 8 (EAN8 +2), 9 (EAN8 +5). Sample: &Type=7.
  2. Set the data property with the value to encode. Type is String.
    User should only provide 7 digits, and DO NOT include last digit checksum character.
    Servlet URL Parameter: Data.
    • Valid Data Scope:
      • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    • Valid Data Format:7 digits. There are totally 8 digits in EAN-8 barcode, first 7 digits are barcode value, and last digit is the checksum digit, which is generated by barcode library automatically.
    • Sample: barcode.Data = "1234567".
  3. Set the sData property with the supplement value to encode. Type is String.
    Provide 2 digits for barcode type EAN8_2, and provide 5 digits for type EAN8_5.
    Sample for Linear.EAN8_2: barcode.setSData("12").
    Sample for Linear.EAN8_5: barcode.setSData("12345").
    Servlet URL Parameter: SData.
  4. addCheckSum property is not applied here. Barcode Library will always add a check character in the last digit (modulo 10).
  5. 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.
  6. 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
  7. 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).
