CvInvokeContourArea Method

public static double ContourArea(
	IInputArray contour,
	bool oriented = false
)

Public Shared Function ContourArea ( 
	contour As IInputArray,
	Optional oriented As Boolean = false
) As Double

public:
static double ContourArea(
	IInputArray^ contour, 
	bool oriented = false
)

static member ContourArea : 
        contour : IInputArray * 
        ?oriented : bool 
(* Defaults:
        let _oriented = defaultArg oriented false
*)
-> float 

Parameters

contour

Type: Emgu.CVIInputArray
Input vector of 2D points (contour vertices), stored in std::vector or Mat.

oriented (Optional)

Type: SystemBoolean
Oriented area flag. If it is true, the function returns a signed area value, depending on the contour orientation (clockwise or counter-clockwise). Using this feature you can determine orientation of a contour by taking the sign of an area. By default, the parameter is false, which means that the absolute value is returned.
