IntermediateResultManager
The IntermediateResultManager class is responsible for handling intermediate results obtained during the process of an image. It offers methods to both register and deregister receivers of these intermediate results, as well as to retrieve the original image data.
| Name | Description |
|---|---|
| addResultReceiver() | Adds a IntermediateResultReceiver object as the receiver of intermediate results. |
| removeResultReceiver() | Removes the specified IntermediateResultReceiver object. |
| removeAllResultReceivers() | Removes all CapturedResultReceiver objects. |
| getOriginalImage() | Retrieves the original image data. |
addResultReceiver
Adds a IntermediateResultReceiver object as the receiver of intermediate results.
Syntax
addResultReceiver(receiver: IntermediateResultReceiver): Promise<void>;
Parameters
receiver: the receiver object, of type IntermediateResultReceiver.
Return Value
None.
Code snippet
router = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
const intermediateResultReceiver = new Dynamsoft.CVR.IntermediateResultReceiver();
intermediateResultReceiver.onDecodedBarcodesReceived = (result, info) => {
/* Do something with the result */
};
const intermediateResultManager = router.getIntermediateResultManager();
await intermediateResultManager.addResultReceiver(intermediateResultReceiver);

removeResultReceiver
Removes the specified IntermediateResultReceiver object.
Syntax
removeResultReceiver(receiver: IntermediateResultReceiver): Promise<void>;
Parameters
receiver: the receiver object, of type IntermediateResultReceiver.
Return Value

router = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
const intermediateResultReceiver = new Dynamsoft.CVR.IntermediateResultReceiver();
intermediateResultReceiver.onDecodedBarcodesReceived = (result, info) => {
/* Do something with the result */
};
const intermediateResultManager = router.getIntermediateResultManager();
await intermediateResultManager.addResultReceiver(intermediateResultReceiver);
