code39.ChecksumEnabled = true;
// Display Code 39 checksum in the human-readable text
code39.DisplayChecksum = true;

//Set Code 39 image size

// Code 39 unit of measure, Pixel, Cm and Inch supported.
code39.BarcodeUnit = BarcodeUnit.Pixel;
// Code 39 image resolution in DPI.
code39.DPI = 72;
// Code 39 module bar width, ie. Width of the narrowest bar (X dimention), default is 1 pixel.
code39.X = 3;
// Code 39 module bar height (Y dimention)
code39.Y = 60;
// Code 39 wide bar width vs narrow bar. Valid from 2.of-3.0f inclusive.
code39.WideNarrowRatio = 2.0f;
// Space between character symbol, a multiple of X.
code39.I = 1.0f;

// Left margin size, a 10X space is automatically added according to specification.
code39.LeftMargin = 0;
// Right margin size, a 10X space is automatically added according to specification.
code39.RightMargin = 0;
code39.TopMargin = 0;
code39.BottomMargin = 0;
// Code 39 image orientation: 0, 90, 180, 270 degrees supported
code39.Orientation = KeepAutomation.Barcode.Orientation.Degree0;

//Set Code 39 human readable text style

// Display human readable text
code39.DisplayText = true;
code39.TextFont = new Font("Arial", 10f, FontStyle.Regular);
// Space between barcode and text
code39.TextMargin = 6;
// Print Code 39 Start & Stop Char *in barcode text
code39.DisplayStartStop = true;
// Print Code 39 barcodes in Png, Jpeg, Gif, Tiff, Bmp, etc. image formats.
code39.ImageFormat = ImageFormat.Png;

// Generate and save Code 39 barcodes to image format
