Creating UPC-A barcode in C# class example:

   using System;
using System.Collections.Generic;
using System.Text;
using OnBarcode.Barcode;
using System.Drawing.Imaging;
using System.Drawing;


Linear upca = new Linear();

// Barcode data to encode
upca.Data = "12345678912";
// Barcode symbology type
//upca.Type = BarcodeType.UPCA;
upca.Type = BarcodeType.UPCA_2;
// This property is not working in UPC-A.
// According to UPC-A specification, our library will always encode checksum for you.
upca.AddCheckSum = true;

/*
UPC-A Barcode Supplement 2, 5 digits
*/
// UPC-A supplement data, 2 digits or 5 digits
upca.SupData = "12";
// This is a multiplicator of the bar height (Y); The default is 0.8 (80%).
upca.SupHeight = 0.8f;
// The separation between the barcode and the supplement barcode. Default is 15 pixel.
upca.SupSpace = 15;
/*
* Barcode Image Related Settings
*/
// Unit of meature for all size related setting in the library.
upca.UOM = UnitOfMeasure.PIXEL;
// Bar module width (X), default is 1 pixel;
upca.X = 1;
// Bar module height (Y), default is 60 pixel;
upca.Y = 60;
// Barcode image left, right, top, bottom margins. Defaults are 0.
upca.LeftMargin = 0;
upca.RightMargin = 0;
upca.TopMargin = 0;
upca.BottomMargin = 0;
// Image resolution in dpi, default is 72 dpi.
upca.Resolution = 72;
// Created barcode orientation.
//4 options are: facing left, facing right, facing bottom, and facing top

upca.Rotate = Rotate.Rotate0;

/*
* Linear barcodes human readable text styles
*/
// Display human readable text under the barcode
upca.ShowText = true;
// Display checksum digit at the end of barcode data.
upca.ShowCheckSumChar = true;
// Human readable text font size, font family and style
upca.TextFont = new Font("Arial", 9f, FontStyle.Regular);
// Space between barcode and text. Default is 6 pixel.
upca.TextMargin = 6;

// Generate UPC-A and encode barcode to gif format
upca.Format = System.Drawing.Imaging.ImageFormat.Gif;
upca.drawBarcode("C:\\upca.gif");

/*
You can also call other drawing methods to generate barcodes

public void drawBarcode(Graphics graphics);

public void drawBarcode(string filename);

public Bitmap drawBarcode();

public void drawBarcode(Stream stream);
