C# GS1-128 / EAN-128 Generator Introduction Top
GS1-128, former known as EAN-128, UCC-128, USS-128, is alphanumeric linear barcode developed on Code 128, however, using GS1 standard.
C# GS1-128 Generator is one of the functions in OnBarcode's Barcode in .NET Generation Controls, which supports generating & printing GS1-128 / EAN-128 and 20+ other linear & 2D bar codes for C# applications.
OnBarcode C# Barcode Generator makes it easy to generate, create GS1-128 and other linear & 2d barcodes in Microsoft Word.
OnBarcode provides several EAN-128 Generator components and software, including GS1 128 .NET, GS1 128 Java, GS1 128 VB.NET, GS1 128 ASP.NET, GS1 128 Generator.
This document is providing a detailed C# source code about generating GS1-128 barcodes in C# class using Barcode in C# generation component. Complete GS1-128 custmoization settings is included in C# GS1-128 generation guide.
GS1-128 Barcode Basic Characteristics in C#TopEncodable character set
Note: Using C#.NET Barcode Generator library, you shall not add function characters, code set selection characters, start and stop characters. OnBarcode barcode
generator library will insert them into the GS1-128 barcode symbol automatically.
GS1-128 check digit character
Same as Code 128, GS1-128 barcode has one mandatory symbol check character. The check digit character will not be displayed in the HRI (human readable interpretation).
In GS1-128 barcode generator C# library, the property AddCheckSum is not applicable. The barcode encoder library will automatically add one check character before the stop character in every GS1-128 barcode symbol. GS1-128/EAN-128 Barcode Dimension Size in C#Top
In GS1-128 barcode generator C# library, you may use the following barcode dimension size properties:
C#.NET source code: set GS1-128 barcode image sizes.
Linear barcode = new Linear(); // encode two AI element with data message barcode.Data = "(00)395123451234567895(01)09501101530003"; // Barcode symbology type. barcode.Type = BarcodeType.EAN128; /* * Barcode Image Related Settings */ // Unit of meature for all size related setting in the library. barcode.UOM = UnitOfMeasure.PIXEL; // Bar module width (X), default is 1 pixel; barcode.X = 2; // Bar module height (Y), default is 60 pixel; barcode.Y = 60; // Barcode image left, right, top, bottom margins. Defaults are 0. barcode.LeftMargin = 0; barcode.RightMargin = 0; barcode.TopMargin = 0; barcode.BottomMargin = 0; // Image resolution in dpi, default is 72 dpi. barcode.Resolution = 300; // Created barcode orientation. //4 options are: facing left, facing right, facing bottom, and facing top barcode.Rotate = Rotate.Rotate0; /* * Linear barcodes human readable text styles */ // Display human readable text under the barcode barcode.ShowText = true; // Human readable text font size, font family and style barcode.TextFont = new Font("Arial", 9f, FontStyle.Regular); // Space between barcode and text. Default is 6 pixel. barcode.TextMargin = 6; // Generate Code-128 and encode barcode to png format barcode.Format = System.Drawing.Imaging.ImageFormat.Png; barcode.drawBarcode("C://Projects//OnBarcode.com//csharp-gs1-128-barcode-size.png"); 
GS1 128 barcode property settings in C#Top
.NET Barcode Generator library has provided 20+ property settings to customize the generated GS1-128 barcode images.
