CogPolygon.AreaCenter Method

CogPolygon AreaCenter Method

Cognex VisionPro 9.8

Compute the centroid of this polygon. Generates an error if there are fewer than 3 vertices.

Namespace: Cognex.VisionPro
Assembly: Cognex.VisionPro.Core (in Cognex.VisionPro.Core.dll) Version: 75.1.0.0

Syntax

public void AreaCenter(
	out double x,
	out double y
)

public void AreaCenter(
	out double x,
	out double y
)

Public Sub AreaCenter ( 
	<OutAttribute> ByRef x As Double,
	<OutAttribute> ByRef y As Double
)

Public Sub AreaCenter ( 
	<OutAttribute> ByRef x As Double,
	<OutAttribute> ByRef y As Double
)

public:
void AreaCenter(
	[OutAttribute] double% x, 
	[OutAttribute] double% y
)

public:
void AreaCenter(
	[OutAttribute] double% x, 
	[OutAttribute] double% y
)

Parameters

x: Type: System Double
X-coordinate of the center.

y: Type: System Double
Y-coordinate of the center.

Exceptions

Exception	Condition
CogShapeDegeneratePolygonException	NumVertices < 3.

Remarks

Computes the centroid of this polygon. The polygon must have at least three vertices.

If the polygon is Complex, the value that AreaCenter(Double , Double ) computes will not be valid, but AreaCenter(Double , Double ) will not return an error. For Complex polygons use ArcCenter(Double , Double ) instead.
