C# Sample code
     BarCode upca = new BarCode();
// Set barcode symbology type to UPCA, UPCASup2, UPCASup5
upca.Symbology = KeepAutomation.Barcode.Symbology.UPCASup2;
// Set UPC-A encoding code value. Valid input: 0-9. Length: 11 digits without checksum.
upca.CodeToEncode = "11223344551";
// Unit of measure, Pixel, Cm and Inch supported.
upca.BarcodeUnit = BarcodeUnit.Pixel;
// UPC-A image resolution in DPI.
upca.DPI = 72;

//Apply checksum for UPC-A barcode.
upca.ChecksumEnabled = true;
// Display checksum in the UPC-A barcode text
upca.DisplayChecksum = true;

// Set UPC-A image size

// UPC-A bar module width (X dimention), default value is 1 pixel.
upca.X = 2;
// UPC-A bar module height (Y dimention), default is 50 pixel.
upca.Y = 60;
// Image left margin size, 10X is automatically added to go with specification.
upca.LeftMargin = 0;
// Image right margin size, 10X is automatically added to go with specification.
upca.RightMargin = 0;
// UPC-A image top margin size
upca.TopMargin = 0;
// UPC-A image bottom margin size
upca.BottomMargin = 0;
// UPC-A orientation, 90, 180, 270 degrees supported
upca.Orientation = KeepAutomation.Barcode.Orientation.Degree0;

// UPC-A supplement code of 2 or 5 digits
upca.SupplementCode = "02";
// UPC-A supplement bar height vs primary bar height ratio.
upca.SupplementHeight = 0.7f;
// Space between barcode and supplement barcode
upca.SupplementSpace = 15;

// Set UPC-A human readable text style

// Display human readable text
upca.DisplayText = true;
upca.TextFont = new Font("Arial", 10f, FontStyle.Regular);
// Space between barcode and text
upca.TextMargin = 6;

// enerate UPC-A barcodes in image format JPEG
upca.generateBarcodeToImageFile("C://barcode-upca-csharp.jpeg");

/* Create UPC-A barcodes in Stream object
upca.generateBarcodeToStream(".NET System.IO.Stream Object");
