Cv_2DRotationMatrix Method (CvPoint2D32f, Double, Double, CvMat)

OpenCvSharp Class Library

Calculates affine matrix of 2d rotation.

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public static CvMat _2DRotationMatrix(
	CvPoint2D32f center,
	double angle,
	double scale,
	out CvMat mapMatrix
)

Public Shared Function _2DRotationMatrix ( 
	center As CvPoint2D32f,
	angle As Double,
	scale As Double,
	<OutAttribute> ByRef mapMatrix As CvMat
) As CvMat

public:
static CvMat^ _2DRotationMatrix(
	CvPoint2D32f center, 
	double angle, 
	double scale, 
	[OutAttribute] CvMat^% mapMatrix
)

static member _2DRotationMatrix : 
        center : CvPoint2D32f * 
        angle : float * 
        scale : float * 
        mapMatrix : CvMat byref -> CvMat

Parameters

center: Type: OpenCvSharpCvPoint2D32f
Center of the rotation in the source image.
angle: Type: SystemDouble
The rotation angle in degrees. Positive values mean couter-clockwise rotation (the coordiate origin is assumed at top-left corner).
scale: Type: SystemDouble
Isotropic scale factor.
mapMatrix: Type: OpenCvSharpCvMat
Pointer to the destination 2×3 matrix.

Return Value

Type: CvMat
The transformation maps the rotation center to itself. If this is not the purpose, the shift should be adjusted.
