using IronBarCode;

// Creating a barcode is as simple as:
var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8);

// Reading a barcode is easy with IronBarcode:
var resultFromFile = BarcodeReader.Read(@"file/barcode.png"); // From a file
var resultFromPdf = BarcodeReader.ReadPdf(@"file/mydocument.pdf"); // From PDF use ReadPdf

// After creating a barcode, we may choose to resize and save which is easily done with:
myBarcode.ResizeTo(400, 100);
myBarcode.SaveAsImage("myBarcodeResized.jpeg");
