// Title: Reset ProcessorSettings after multithreaded barcode processing
// Description: Demonstrates generating barcode images, configuring multithreaded recognition, and resetting ProcessorSettings to defaults.
// Category-Description: This example belongs to the Aspose.BarCode multithreading and performance tuning category. It showcases key API classes such as BarcodeGenerator, BarCodeReader, and ProcessorSettings, illustrating typical use cases like batch barcode generation, parallel recognition, and proper cleanup of processor configurations. Developers often need to adjust these settings for optimal CPU utilization and then restore defaults to avoid side effects in subsequent operations.
// Prompt: Write a script that resets ProcessorSettings to default values after completing a multithreaded barcode job.
// Tags: code128, generation, recognition, multithreading, png, barcodgenerator, barcodereader, processorsettings
