// Title: Render barcode to file stream using Save method
// Description: Demonstrates generating a Code128 barcode and saving it directly to a file stream in PNG format.
// Category-Description: This example belongs to the Aspose.BarCode generation category, illustrating how to use BarcodeGenerator with EncodeTypes and BarCodeImageFormat to create barcodes. Typical use cases include creating barcode images for inventory, shipping labels, or product packaging, where developers need to write the output directly to a stream for further processing or storage.
// Prompt: Render barcode directly to a file stream using Save method, then close the stream to release resources.
