IntermediateResultReceiver
The IntermediateResultReceiver class is designed as a standardized way for retrieving intermediate results in image processing workflows in the Dynamsoft Capture Vision architecture. It adopts an event-driven approach, with events triggered for specific types of results, such as pre-detected regions, localized barcodes, etc. Each event is optional, allowing flexibility and customization based on the needs of the application.
