Syntax

public double PointPolygonTest(
	Point2f pt,
	bool measureDist
)

Public Function PointPolygonTest ( 
	pt As Point2f,
	measureDist As Boolean
) As Double

public:
double PointPolygonTest(
	Point2f pt, 
	bool measureDist
)

member PointPolygonTest : 
        pt : Point2f * 
        measureDist : bool -> float

pt: Type: OpenCvSharp.CPlusPlusPoint2f
Point tested against the contour.
measureDist: Type: SystemBoolean
If true, the function estimates the signed distance from the point to the nearest contour edge. Otherwise, the function only checks if the point is inside a contour or not.

Type: Double
Positive (inside), negative (outside), or zero (on an edge) value.
