Cv2PointPolygonTest Method (IEnumerablePoint2f, Point2f, Boolean)

Checks if the point is inside the contour. Optionally computes the signed distance from the point to the contour boundary.

Syntax

public static double PointPolygonTest(
	IEnumerable<Point2f> contour,
	Point2f pt,
	bool measureDist
)

Public Shared Function PointPolygonTest ( 
	contour As IEnumerable(Of Point2f),
	pt As Point2f,
	measureDist As Boolean
) As Double

public:
static double PointPolygonTest(
	IEnumerable<Point2f>^ contour, 
	Point2f pt, 
	bool measureDist
)

static member PointPolygonTest : 
        contour : IEnumerable<Point2f> * 
        pt : Point2f * 
        measureDist : bool -> float

contour: Type: System.Collections.GenericIEnumerablePoint2f
Input contour.
pt: Type: OpenCvSharpPoint2f
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.
