ISBN Barcode Introduction
ISBN is also known as International Standard Book Number, Bookland EAN, ISBN-13, ISBN-10, ISBN+5, ISBN+2, ISBN Supplement 5/Five-digit Add-On, ISBN Supplement 2/Two-digit Add-On.
ISBN stands for International Standard Book Number - a unique identifier assigned to each edition of every published book and book-like product. The purpose of the ISBN is to establish and identify one title or edition of a title from one specific publisher and is unique to that edition, allowing for more efficient marketing of products by booksellers, libraries, universities, wholesalers and distributors.
The Components of an ISBN
The ISBN number is 13 digits long and consists of four or five parts:
  • In ISBN, a GS1 Prefix, either 978 or 979
  • The country of origin or language code
  • The publisher number which is assigned by the national ISBN agency
  • The item number
  • The checksum character which ensures that each ISBN is valid, meaning that the number is correct
Add-On or Supplement code
The Add-On Symbols were designed to encode information supplementary to that in the main bar code symbol on periodicals and paperback books. The Add-On can be composed of 2 or 5 digits only. For ISBN barcodes a Five-digit Add-On is usually used for the Retail Suggested Price.

ISBN Encoding Data Scope
ISBN Barcode for Java supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to Generate ISBN Barcode in Java Class?
The following Java code illustrates how to create a ISBN barcode, and output to various formats.
1     Linear linear = new Linear(); 
2 linear.setType(Linear.ISBN);
3 linear.setData("978047082163");
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 ISBN (line 2)
  • Set ISBN barcode data to encode (line 3)
  • Encode generated ISBN barcode into gif image file (line 4)
  • Generate ISBN and output to BufferedImage object (line 5)
  • Generate ISBN in bitmap and output to byte[] (line 6)
  • Generate ISBN and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
  • Generate ISBN and output to OutputStream (line 10-11)
How to Generate ISBN Barcode Image in Java Web Applications?
There are two methods to create ISBN 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=978456789012&Type=ISBN" />
      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" />

ISBN Barcode Property Settings
  1. Set the type property to Linear.ISBN, Linear.ISBN_2 or Linear.ISBN_5
    Servlet URL Parameter: "Type". Value: 13 (ISBN), 46 (ISBN +2), 14 (ISBN +5). Sample: &Type=13
  2. Set the data property with the value to encode. Type is String.
    Servlet URL Parameter: Data.
    User should only provide 12 digits, and DO NOT include last digit checksum character.
    • Valid Data Scope:
      • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    • Valid Data Format:
      • 12 digits. There are totally 13 digits in ISBN barcode, first 12 digits are barcode value, and last digit is the checksum digit, which is generated by barcode library automatically.
        Valid data should be started with "978" or "979".
    • Sample: "123456789012".
  3. Set the sData property with the supplement value to encode. Type is String.
    Provide 2 digits for barcode type ISBN_2, and provide 5 digits for type ISBN_5.
    Sample for Linear.ISBN_2: "12".
    Sample for Linear.ISBN_5: "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).
