.NET WinForms ITF-14 Barcode Property Settings
1. Generate ITF-14 in .NET Class
The following C#.net code illustrates how to generate a ITF-14 barcode in a C# class
BarcodeLib.Barcode.Linear barcode = new BarcodeLib.Barcode.Linear();
barcode.Type = BarcodeType.ITF14;
// should be 13 digits
barcode.Data = "3011234500001";
barcode.BearerBars = BearerBar.Frame;
barcode.BearerBarWidth = 3;
barcode.N = 3;
barcode.UOM = UnitOfMeasure.PIXEL;
barcode.BarWidth = 1;
barcode.BarHeight = 80;
barcode.LeftMargin = 10;
barcode.RightMargin = 10;
barcode.TopMargin = 10;
barcode.BottomMargin = 10;
barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;
// more barcode settings here
// save barcode image into your system
barcode.drawBarcode("c://barcode.png");
// generate barcode & output to byte array
byte[] barcodeInBytes = barcode.drawBarcodeAsBytes();
// generate barcode to Graphics object
Graphics graphics = ...
barcode.drawBarcode(graphics);
// generate barcode and output to Bitmap object
Bitmap barcodeInBitmap = barcode.drawBarcode();
// generate barcode and output to HttpResponse object
HttpResponse response = ...;
barcode.drawBarcode(response);
// generate barcode and output to Stream object
Stream stream = ...;
barcode.drawBarcode(stream);
