Calculates the matrix of an affine transform such that: (x'_i,y'_i)^T=map_matrix (x_i,y_i,1)^T where dst(i)=(x'_i,y'_i), src(i)=(x_i,y_i), i=0..2.

Syntax

C#
public static RotationMatrix2D<double> GetAffineTransform(
	PointF[] src,
	PointF[] dest
)
Visual Basic
Public Shared Function GetAffineTransform ( _
	src As PointF(), _
	dest As PointF() _
) As RotationMatrix2D(Of Double)
Visual C++
public:
static RotationMatrix2D<double>^ GetAffineTransform(
	array<PointF>^ src, 
	array<PointF>^ dest
)

Parameters

src
Type: array<System.Drawing..::..PointF>[]()[][]
Coordinates of 3 triangle vertices in the source image. If the array contains more than 3 points, only the first 3 will be used
dest
Type: array<System.Drawing..::..PointF>[]()[][]
Coordinates of the 3 corresponding triangle vertices in the destination image. If the array contains more than 3 points, only the first 3 will be used

Return Value

The 2x3 rotation matrix that defines the Affine transform
