CogTransform2DLinear.MapAngle Method

CogTransform2DLinear MapAngle Method

Cognex VisionPro 9.20

Maps the given angle (in radians) through this transform and returns the result (in radians).

Namespace: Cognex.VisionPro
Assembly: Cognex.VisionPro.Core (in Cognex.VisionPro.Core.dll) Version: 80.0.0.0

Syntax

public double MapAngle(
	double angle
)

public double MapAngle(
	double angle
)

Public Function MapAngle ( 
	angle As Double
) As Double

Public Function MapAngle ( 
	angle As Double
) As Double

public:
double MapAngle(
	double angle
)

public:
double MapAngle(
	double angle
)

Parameters

angle: Type: System Double
The angle to map.

Return Value

Type: Double

The mapped angle.

Remarks

Maps the given angle in radians through this transformation.

The operation of MapAngle(Double) is equivalent to creating a unit vector at the given angle, mapping the vector, and then computing the rotation angle of the mapped vector. The following code uses other VisionPro methods to illustrate what MapAngle(Double) does. This example does not represent actual code you need to enter.
