1. EAN 13 Barcode Introduction
A European Article Number (EAN) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in North America. The EAN-13 barcode is defined by the standards organisation GS1. It is also called a Japanese Article Number (JAN) in Japan. UPC, EAN, and JAN numbers are collectively called Global Trade Item Numbers (GTIN), though they can be expressed in different types of barcodes.
The EAN-13 barcodes are used worldwide for marking retail goods. The less commonly used EAN-8 barcodes are used also for marking retail goods; however, they are usually reserved for smaller items, for example confectionery.


Sample of an EAN-13 Barcode

The value to encode by EAN-13 has the following structure:
  • 2 or 3 digits for Number System or Country Code
  • 5 or 4 digits for Manufacturer (Company) Code or prefix
  • 5 digits for Product Code
  • 1 digit for checksum
Each country has a numbering authority which assigns manufacturer codes to companies within its jurisdiction.

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.

  2. Create a new virtual directory, named barcode.
  3. Restart IIS.
  4. Test your installation, goto http://YourDomain:port/barcode/linear.aspx?Type=EAN13&Data=012345678900
  5. To create barcode image in your ASP.NET application, you can pass the url to IMG tag src value. For example, <img src="http://YourDomain:port/barcode/linear.aspx?Type=EAN13&Data=012345678900" />


 
4. How to Generate EAN 13 Barcode Image through Web Controller in ASP.NET?
  1. Integrate Barcode Controller to your ASP.NET project.
    1. Copy BarcodeLib.Barcode.dll to the folder bin of your web application the barcodes are needed for.
    2. Copy linear.aspx file to your web application.
  2. Add barcode library to your Visual Studio Toolbox.
    1. Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
    2. Right click Toolbox, click menu Choose Items...
    3. Goto .NET Framework Components tab.
    4. Check component LinearWebForm, and its namespace is BarcodeLib.Barcode.Linear
    5. If no component found, click Browse... button and select BarcodeLib.Barcode.dll file.
  3. Now you can see the component displayed on Toolbox. You can drag LinearWebForm on your aspx page, change barcode setting through properties window.


 
5. How to Generate EAN 13 Barcode Image through Windows Controller in .NET?
  1. Add Reference BarcodeLib.Barcode.dll to your project. Do not copy the dll to the bin directory, Visual Studio will do so, during project compilation time.
    1. In your .NET windows project, right click mouse over Refereces in your Solution Explorer window. Then click menu "Add Reference ...".
    2. Add BarcodeLib.Barcode.dll to your project.
  2. Add barcode library to your Visual Studio Toolbox.
    1. Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.

  3. Now you can see the component displayed on Toolbox. You can drag LinearWinForm on your form, change barcode setting through properties widnow.


 
6. How to Generate EAN 13 Barcode Image in .NET class?
  1. Add Reference BarcodeLib.Barcode.dll to your .NET project (ASP.NET website, Forms, any .NET project)
    In your .NET class. 
    BarcodeLib.Barcode.Linear.Linear barcode = BarcodeLib.Barcode.Linear.Linear();
barcode.Data = "your barcode data";
// other barcode settings.
                        
// save barcode image into your system
barcode.drawBarcode("c:/barcode.gif");
Above code written in C# 2005

* Please set properties UOB and Resolution, before you set any image size related properties like barWidth, margin.


 
7. How to Save EAN 13 Barcode Image?

8. EAN 13 Barcode Property Settings
  • Set the Type property to BarcodeType.EAN13 or BarcodeType.EAN13_2 or BarcodeType.EAN13_5
  • Set the Data property with the value to encode. Type is string.
    User should only provide 12 digits, and DO NOT include last digit checksum character.
  • Set the SData property with the supplement value to encode. Type is string.

  • Setting up barcode image size:
    • Set property UOM (Unit of Measure) for properties BarWidth, BarHeight, LeftMargin and TopMargin.
      Default is UnitOfMeasure.Pixel (0). Valid values are UnitOfMeasure.Pixel (0), UnitOfMeasure.CM (1), UnitOfMeasure.Inch (2).
    • Set the BarWidth (for bar cell width) and BarHeight (for bar cell height) properties. Both types are float.
    • Set the LeftMargin and TopMargin properties, and types are both float.
    • Set the Resolution property (Value is expressed in DPI - Dots per inch). This property is not working in Windows Controller, we will use end user's windows resultion.
  • Setting up text style in barcode image:
    • Set the ShowText properties. If this value is true, barcode data will be displayed with the barcode.
    • Set the TextFont property. The font used to display text in barcode image.
  • Set the Format property for barcode image type. Value can be "gif", "jpg", "png", and "bmp", default is "png".
  • Set BearerBars property, if you want to draw borders around barcode image. Value can be BearerBar.None (no bear bars), BearerBar.Frame (top, bottom, left, right borders drawn), BearerBar.TopBottom (only top, bottom's are drawn).
  • Set Rotate property, if you want to rotate barcode image.
    Value can be
    0 (RotateOrientation.BottomFacingDown),
    1 (RotateOrientation.BottomFacingLeft),
    2 (RotateOrientation.BottomFacingUp),
    3 (RotateOrientation.BottomFacingRight)
  • AddCheckSum property is not applied here. Barcode Library will always add a check character in the last digit (modulo 10).
