// Title: Generate Mailmark barcode and embed in PDF
// Description: Demonstrates creating a Mailmark barcode with default settings and inserting it into a PDF document.
// Category-Description: This example belongs to the Aspose.BarCode complex barcode generation category, showcasing the use of ComplexBarcodeGenerator and MailmarkCodetext to produce Mailmark symbology. Typical use cases include embedding postal barcodes into documents such as PDFs for mailing automation. Developers often need to generate barcode images and combine them with other file formats using Aspose.Pdf.
// Prompt: Generate a Mailmark barcode with default settings and embed the image into a PDF document.
