Detailed Description

This interface holds a single contour detection result and is used to access its properties.

Usually you get the LContourResult object from the ILContourResults::Item() function. You can then use this interface to access to the contour informations and draw the result on graphics windows.

Example Code

C++

ILContourResultPtr result = contourResults->Item(i);
ILPolygonPtr contour = result->Contour;
double avgMag = result->GetFeature(LPVContourFeatures::LPVContourAvgMag);

C#

LContourResult result = contourResults.Item(i);
LPolygon contour = result.Contour;
double avgMag = result.GetFeature(LPVContourFeatures.LPVContourAvgMag);

COM

ILContourResultPtr result = contourResults->Item(i);
ILPolygonPtr contour = result->Contour;
double avgMag = result->GetFeature(LPVContourFeatures::LPVContourAvgMag);
