C# Imaging - EAN-8 Generating Tutorial

Overview on EAN-8 Barcode Library in C#

EAN-8 is a numeric linear barcode symbology with a fixed length of 8 digits. RasterEdge .NET DocImage Barcode Add-on component enables Visual C# developers to create EAN-8 barcode image with best quality. All the EAN-8 barcodes generated with this .NET barcode control are compatible with the latest GS1 General Specification, with the last checksum digit character automatically added. There are only two project requirements: .NET Framework 2.0 or later version, and Microsoft Visual Studio 2005 or above.

Detailed features are listed below:

Write EAN-8, EAN-8+2, EAN-8+5 (EAN-8 with supplement digits) using C# coding

Create EAN-8 in .NET Windows application, ASP.NET web form / web site & C# Class Library

Draw and print EAN-8 in png, jpeg, tiff and bmp raster image files

Generate and embed EAN-8 bar codes in PDF, TIFF, MS Office Word, Excel and PowerPoint documents

User can freely define the accurate location of EAN-8 barcode image with C#

Automatically add checksum and minimum quiet zone for scannable EAN-8 output

Besides this C# barcoding guide, we also provide VB.NET Codabar solution for VB.NET programmers. Here is the detailed Codabar Generation in Visual Basic.NET Tutorial.

C# Code for Customizing EAN-8 Barcode Generation

You can easily generator EAN-8 barcode and save it  to image files/object using this C#.NET barcode generator control. The following steps will show how to create a EAN-8 type barcode encoding numeric data text "123456789" into the image object with XImage.Barcode.Creator.

Please copy the sample code as follow to generator a EAN-8 barcode.

private static Linear CreateBarcode()
        {
            Linear barcode = new Linear();// create a barcode
            barcode.Type = BarcodeType.EAN8;// select barcode type

            barcode.BarcodeHeight = 200;
            barcode.AutoResize = true;

            //convert barcode to a bitmap and save it to image file
            //Bitmap bmp = barcode.ToImage();
            //bmp.Save(@"C:\barcode.bmp");

            return barcode;
        }

Create EAN-8 Barcode on Image in C#.NET

Here is a C# example for developers to write and embed an EAN-8 barcode on a png image from the local disk C, with the detailed location specified by users with the X and Y coordinates. Besides the PNG image format, other supported common image formats are JPEG, BMP and GIF.

private static void AddBarcodeToImage(Linear barcode)
        {
            REImage image = new REImage(inputDirectory + "Sample.png");
            barcode.DrawBarcode(image, 150F, 150F);
            image.Save(ImageType.PNG, outputDirectory + "Sample_Barcode.png");
        }

Generate EAN-8 on Document Page in C#.NET

Use following C# code to generate EAN-8 on defined page area of a PDF, multi-page TIFF, Microsoft Office Word (.docx), Excel(.xlsx) or PowerPoint(.pptx) document.
