| MatPointPolygonTest Method |
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
)
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
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:
DoublePositive (inside), negative (outside), or zero (on an edge) value.
