C++ API Reference - CBarcodeReader Result Methods
| Method | Description |
|---|---|
GetAllTextResults |
Get all recognized barcode results. |
FreeTextResults |
Free memory allocated for text results. |
GetIntermediateResults |
Get intermediate results. |
FreeIntermediateResults |
Free memory allocated for the intermediate results. |
GetAllTextResults
Get all recognized barcode results.
int CBarcodeReader::GetAllTextResults (TextResultArray** pResults)
Parameters
[out] pResults Barcode text results returned by the last called function DecodeFile / DecodeFileInMemory / DecodeBuffer / DecodeBase64String / DecodeDIB. The pResults is allocated by the SDK and should be freed by calling the function FreeTextResults.
Return value
Returns error code (returns 0 if the function operates successfully).
You can call GetErrorString to get detailed error message.
Code Snippet
CBarcodeReader* reader = new CBarcodeReader();
reader->InitLicense("t0260NwAAAHV***************");
TextResultArray* pResults;
int errorCode = reader->DecodeFile("C:\\Program Files (x86)\\Dynamsoft\\{Version number}\\Images\\AllSupportedBarcodeTypes.tif", "");
reader->GetAllTextResults(&pResults);
CBarcodeReader::FreeTextResults(&pResults);
delete reader;
FreeTextResults
Free memory allocated for text results.
static void CBarcodeReader::FreeTextResults (TextResultArray** pResults)
Parameters
[in] pResults Text results.

reader->GetAllTextResults(&pResults);
CBarcodeReader::FreeTextResults(&pResults);
delete reader;
GetIntermediateResults
Get intermediate results containing the original image, the colour clustered image, the binarized Image, contours, Lines, TextBlocks, etc.
int CBarcodeReader::GetIntermediateResults (IntermediateResultArray** pResults)
Parameters
