Detailed Description

This interface holds a collection of barcode results.

Usually you get the LBarcodeResults object from the ILBarcode::Detect() as results. You can then use this interface to access individual result and draw the results on graphics windows.

Example Code

C++

ILBarcodeResultsPtr codeResults;
LPVErrorCode err = barcodeDetector->Detect(img, roi, &codeResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = codeResults->Count();
for (int i = 0; i < c; ++i) {
    ILBarcodeResultPtr codeRes = codeResults->Item(i);
    // handle each barcode result
}

C#

LBarcodeResults codeResults;
LPVErrorCode err = barcodeDetector.Detect(img, (LRegion)roi, out codeResults);
if (err != LPVErrorCode.LPVNoError) return;
int c = codeResults.Count();
for (int i = 0; i < c; ++i) {
    LBarcodeResult codeRes = codeResults.Item(i);
    // handle each line result
}

COM

ILBarcodeResultsPtr codeResults;
LPVErrorCode err = barcodeDetector->Detect(img, roi, &codeResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = codeResults->Count();
for (int i = 0; i < c; ++i) {
    ILBarcodeResultPtr codeRes = codeResults->Item(i);
    // handle each barcode result
}
