}

Step 4: Create Barcode Sign Options

Create an instance of BarcodeSignOptions and configure it according to your requirements.

BarcodeSignOptions options = new BarcodeSignOptions("JohnSmith")
{
	// Specify barcode encoding type
	
    EncodeType = BarcodeTypes.Code128,
    // Set signature position (left)
	Left = 50,
	// Set signature position (top)
    Top = 150,
	// Set barcode width
    Width = 200,
	// Set barcode height
    Height = 50
};

Step 5: Sign the Document

Invoke the Sign method of the Signature object, passing the output file path and barcode sign options.

SignResult result = signature.Sign(outputFilePath, options);
