Checks if the point is inside the contour.
Optionally computes the signed distance from the point to the contour boundary.
Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public static double PointPolygonTest( IEnumerable<Point2f> contour, Point2f pt, bool measureDist )
Parameters
- contour
- Type: System.Collections.GenericIEnumerablePoint2f
Input contour. - 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.
Return Value
Type: DoublePositive (inside), negative (outside), or zero (on an edge) value.
