IntermediateResultReceiver

The IntermediateResultReceiver class is designed as a standardized way for retrieving intermediate results in image processing workflows in the Dynamsoft Capture Vision architecture. By implementing the CapturedResultReceiver, you will receive the callback of the various types of captured results, such as pre-detected regions, localized barcodes, etc. Each callback is optional, allowing flexibility and customization based on the needs of the application.
