Barcode Quickstart

  
 
using IronBarCode;
using System.Drawing;
// Creating a barcode is as simple as:
var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8);
// And save our barcode as in image:
myBarcode.SaveAsImage("EAN8.jpeg");
Image myBarcodeImage = myBarcode.Image; // Can be used as Image
Bitmap myBarcodeBitmap = myBarcode.ToBitmap(); // Can be used as Bitmap
// Reading a barcode is easy with IronBarcode:
var resultFromFile = BarcodeReader.Read(@"file/barcode.png"); // From a file
