EAN-8 Barcode Introduction
EAN-8 is a GS1 specified linear barcode symbology, which is also named European Article Number 8, EAN/UCC-8, GS1-8, with variants EAN 8+2, EAN-8 Supplement 2 (a two-digit Add-On), EAN-8 +5, EAN-8 Supplement 5(a five-digit add-on).
  • EAN-8 Encodable Character Set: Numeric digits 0-9
  • EAN-8 Data Length: 7 digits (excluding check digit, which will be automatically added by software)

How to Generate EAN-8 in .NET Applications with C#.NET Demo Code

Below is some detailed Visual C#.NET sample codings for EAN-8 generation in .NET. You can easily adjust multiple barcode properties like bar width, image width, height, quiet zone, resolution, rotation, human-readable-text font/style, etc. Furthermore, several methods are provided to make EAN-8 in stream objects, graphics objects as well as image formats.
using KeepAutomation.Barcode.Bean;

BarCode ean8= new BarCode();
// Set barcode symbology type to EAN8, EAN8Sup2, EAN8Sup5
ean8. Symbology = KeepAutomation.Barcode.Symbology. EAN8;

// Set EAN 8 encoding code value. Valid data: 7 digits numeric digits without checksum.
ean8.CodeToEncode = "0123456";
// Apply checksum for EAN 8 barcode.
ean8.ChecksumEnabled = true;

//Set EAN 8 image size

// Unit of measure, Pixel, Cm and Inch supported.
ean8.BarcodeUnit = BarcodeUnit.Pixel;
// EAN 8 image resolution in DPI.
ean8.DPI = 72;
// EAN 8 bar module width (X dimention)
ean8.X = 2;
// EAN 8 bar module height (Y dimention)
ean8.Y = 60;
// EAN 8 image left margin size, minimum is 10X.
ean8.LeftMargin = 0;
// EAN 8 image right margin size, minimum is 10X.
ean8.RightMargin = 0;
// EAN 8 image top margin size
ean8.TopMargin = 0;
// EAN 8 image bottom margin size
ean8.BottomMargin = 0;
// Orientation, 90, 180, 270 degrees supported
ean8.Orientation = Orientation.Degree0;
// EAN8 supplement code: 2 or 5 digits
ean8.SupplementCode = "02";
// Supplement bar height vs bar height ratio.
ean8.SupplementHeight = 0.8f;
// Space between barcode and supplement barcode
ean8.SupplementSpace = 15;

//Set EAN 8 human readable text style

// Display human readable text
ean8.DisplayText = true;
ean8.TextFont = new Font ("Arial", 10f, FontStyle. Regular);
// Space between barcode and text
ean8.TextMargin = 6;
// Display checksum in the EAN 8 barcode text
ean8. Displaychecksum = true;

// Generate EAN 8 barcodes in image GIF format

// Create EAN 8 barcodes in Stream object
ean8.generateBarcodeToStream(".NET System.IO.Stream Object");

// Draw & Print EAN 8 barcodes to Graphics object
ean8.generateBarcodeToGraphics(".NET System.Drawing.Graphics Object");

// Generate EAN 8 barcodes & write to byte[]
byte[] barcodeInBytes = ean8.generateBarcodeToByteArray();

// Generate EAN 8 barcodes & encode to System.Drawing.Bitmap object
Bitmap barcodeInBitmap = ean8.generateBarcodeToBitmap();

Other image formats including Png, Bmp, Tiff and Jpeg are also available to suit your needs.
