CapturedResultReceiver

The CapturedResultReceiver interface is designed as a standardized way for retrieving captured results in the Dynamsoft Capture Vision architecture. By implementing the CapturedResultReceiver, you will receive the callback of the various types of captured results, such a decoded barcode (Barcode Reader), a recognized text line (Label Recognizer), a detected quad (Document Normalizer), a normalized image (Document Normalizer), or parsed data (Code Parser). The CapturedResultReceiver can add a receiver for any type of captured result or for a specific type of captured result, based on the method that is implemented.

class CapturedResultReceiver

Methods

Method	Description
`onCapturedResultReceived`	The callback invoked when captured results become available. It is triggered once for each image after its processing is completed.
`onDecodedBarcodesReceived`	The callback invoked when decoded barcodes become available. It is triggered once for each image after its processing is completed.
`onParsedResultsReceived`	The callback invoked when parsed results become available. It is triggered once for each image after its processing is completed.
`onProcessedDocumentResultReceived`	The callback invoked when processed document results become available. It is triggered once for each image after its processing is completed.
`onRecognizedTextLinesReceived`	The callback invoked when recognized text lines become available. It is triggered once for each image after its processing is completed.

onCapturedResultReceived

This callback method delivers a CapturedResult - an object representing any kind of captured result item that is captured from an image or a video frame. The callback is triggered each time an image finishes processing, regardless of whether there is a valid result or not.

Future<void> Function(CapturedResult result)? onCapturedResultReceived;

Parameters

result: The captured result, an instance of CapturedResult.

onDecodedBarcodesReceived

This callback method delivers a DecodedBarcodesResult, which is an object representing any captured result of type barcode that is taken from an image or a video frame. The callback is triggered each time an image finishes processing, regardless of whether there is a valid result or not.

Future<void> Function(DecodedBarcodesResult result)? onDecodedBarcodesReceived;

Parameters

result: The decoded barcode result, an instance of DecodedBarcodesResult.

onParsedReultsReceived

This callback method delivers a ParsedResult, which is an object representing any captured result of type parsedResult that is taken from an image or a video frame. The callback is triggered each time an image finishes processing, regardless of whether there is a valid result or not.

Future<void> Function(ParsedResult result)? onParsedResultsReceived;

Parameters

result: The parsed result, an instance of ParsedResult.

onProcessedDocumentResultReceived

This callback method delivers a ProcessedDocumentResult, which is an object representing any captured result of type detectedQuad, deskewedImage and enhancedImage that is taken from an image or a video frame. The callback is triggered each time an image finishes processing, regardless of whether there is a valid result or not.

Future<void> Function(ProcessedDocumentResult result)? onProcessedDocumentResultReceived;

Parameters

result: The document processing results, an instance of ProcessedDocumentResult.

onRecognizedTextLinesReceived

This callback method delivers a RecognizedTextLinesResult, which is an object representing any captured result of type recognizedTextLines that is taken from an image or a video frame. The callback is triggered each time an image finishes processing, regardless of whether there is a valid result or not.

Future<void> Function(RecognizedTextLinesResult result)? onRecognizedTextLinesReceived;

Parameters

result: The text recognition result, an instance of RecognizedTextLinesResult.
