cvPointPolygonTest() публичный статический Метод

Determines whether the point is inside contour, outside, or lies on an edge (or coinsides with a vertex). It returns positive, negative or zero value, correspondingly
public static cvPointPolygonTest ( IntPtr contour, PointF pt, bool measureDist ) : double
contour IntPtr Input contour
pt PointF The point tested against the contour
measureDist bool If true, the function estimates distance from the point to the nearest contour edge
Результат double
