C# EAN-13 Generator Introduction

Top
EAN-13, also known as European Article Number 13, UPC-13, GTIN-13, GS1-13, EAN/UCC-13, is the standard barcode version of European Article Number.
C# EAN-13 Generator is one of the functions in OnBarcode's
Barcode for .NET Generation Controls, which supports generating & printing EAN-13 and 20+ other linear & 2D bar codes for C# applications.
OnBarcode C# Barcode Generator makes it easy to generate, create EAN-13 and other linear & 2d barcodes in Microsoft Word. Here are some detailed tutorials for C# EAN-13 generation and data encoding, size & image setting.
EAN-13 Generator library, SDK & application
OnBarcode provides several
EAN-13 Generator components and software, including
.NET EAN-13,
Java EAN-13,
VB.NET EAN-13,
ASP.NET EAN-13,
EAN-13 Generator.
This document is providing a detailed C# source code about generating EAN-13 barcodes in C# class using
Barcode for C# generation component. Complete EAN-13 custmoization settings is included in
C# EAN-13 generation guide.
How to verify, calculate EAN-13 check digit using C#?

Top
Barcode EAN-13 checksum digit is based on a module 10 calculation, based on the weighted sum of the values of each of the digits in the EAN number system, menufacturer code, and product code.
The steps below explain how to calculate EAN-13 check digit.
- Consider the right-most digit of the message to be in an "odd" position, and assign odd/even to each character moving from right to left.
- Sum the digits in all odd positions, and multiply the result by 3.
- Sum the digits in all even positions.
- Sum the totals calculated in steps 2 and 3.
- The check digit is the number which, when added to the totals calculated in step 4, result in a number evenly divisible by 10.
- If the sum calculated in step 4 is evenly disivisible by 10, the check digit is "0" (not 10).
For example, EAN 13 barcode data is "123456789012", and its correct check digit sum is "8".

The next number of 92 is 100, which will be evenly divisible by 10. |

So the check digit is 8. (100-92=8) |

Creating EAN-13 barcode in C# class example:
using System;
using System.Collections.Generic;
using System.Text;
using OnBarcode.Barcode;
using System.Drawing.Imaging;
using System.Drawing;
Linear ean13 = new Linear();
// Barcode data to encode
ean13.Data = "012345678912";
// Barcode symbology type
//ean13.Type = BarcodeType.EAN13;
ean13.Type = BarcodeType.EAN13_2;
// This property is not working in EAN-13.
// According to EAN 13 specification, our library will always encode checksum for you.
ean13.AddCheckSum = true;
/*
EAN 13 Supplement 2, 5 digits
*/
// EAN-13 supplement data, 2 digits or 5 digits
ean13.SupData = "12";
// This is a multiplicator of the bar height (Y); The default is 0.8 (80%).
ean13.SupHeight = 0.8f;
// The separation between the barcode and the supplement barcode. Default is 15 pixel.
ean13.SupSpace = 15;
/*
* Barcode Image Related Settings
*/
// Unit of meature for all size related setting in the library.
ean13.UOM = UnitOfMeasure.PIXEL;
// Bar module width (X), default is 1 pixel;
ean13.X = 1;
// Bar module height (Y), default is 60 pixel;
ean13.Y = 60;
// Barcode image left, right, top, bottom margins. Defaults are 0.
ean13.LeftMargin = 0;
ean13.RightMargin = 0;
ean13.TopMargin = 0;
ean13.BottomMargin = 0;
// Image resolution in dpi, default is 72 dpi.
ean13.Resolution = 72;
// Created barcode orientation.
//4 options are: facing left, facing right, facing bottom, and facing top
ean13.Rotate = Rotate.Rotate0;
/*
* Linear barcodes human readable text styles
*/
// Display human readable text under the barcode
ean13.ShowText = true;
// Display checksum digit at the end of barcode data.
ean13.ShowCheckSumChar = true;
// Human readable text font size, font family and style
ean13.TextFont = new Font("Arial", 9f, FontStyle.Regular);
// Space between barcode and text. Default is 6 pixel.
ean13.TextMargin = 6;
// Generate EAN-13 and encode barcode to gif format
ean13.Format = System.Drawing.Imaging.ImageFormat.Gif;
ean13.drawBarcode("C:\\ean13.gif");
/*
You can also call other drawing methods to generate barcodes

public void drawBarcode(string filename);
public Bitmap drawBarcode();
public void drawBarcode(Stream stream);
