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

Namespace:  OpenCvSharp
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
Syntax
public double PointPolygonTest(
	Point2f pt,
	bool measureDist
)

Parameters

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.

Return Value

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