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
ean8.generateBarcodeToImageFile("barcode-ean8-csharp.gif");
// 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.
