Detailed Description

This interface holds a collection of path detection results.

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

Example Code

C++

ILPathResultsPtr pathResults;
LPVErrorCode err = pathDetector->Detect(img, rotRectRoi, &pathResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = pathResults->Count();
for (int i = 0; i < c; ++i) {
    ILPathResultPtr result = pathResults->Item(i);
    // handle each path result
}

C#

LPathResults pathResults;
LPVErrorCode err = pathDetector.Detect(img, rotRectRoi, out pathResults);
if (err != LPVErrorCode.LPVNoError) return;
int c = pathResults.Count();
for (int i = 0; i < c; ++i) {
    LPathResult result = pathResults.Item(i);
    // handle each path result
}

COM

ILPathResultsPtr pathResults;
LPVErrorCode err = pathDetector->Detect(img, rotRectRoi, &pathResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = pathResults->Count();
for (int i = 0; i < c; ++i) {
    ILPathResultPtr result = pathResults->Item(i);
    // handle each path result
}
