Linear barcode = new Linear();

barcode.Type = BarcodeType.CODE39;

barcode.Data = "ONBARCODE";

UOM

UOM is short for Unit of Measure, which is the unit of measure for all size related settings in the library. C# Code 39 barcode provides 3 options: Pixel, Cm, and Inch. The default is Pixel.

barcode.UOM = UnitOfMeasure.PIXEL;

I

I is the space between 2 characters in code 39. It is a multiple of X. The default is 1.0f (float).

barcode.I = 1.5f;

N

N is the proportion of wide bar and the narrow. It ranges from 2.0 to 3.0. The default is 2.0f (float).

barcode.N = 2.5f;
