﻿CameraCalibration.GetAffineTransform Method
http://www.emgu.com
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
)```
F#
```static member GetAffineTransform :
src : PointF[] *
dest : PointF[] -> RotationMatrix2D<float>
```

#### 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

Type: RotationMatrix2D<(Of <(<'Double>)>)>
The 2x3 rotation matrix that defines the Affine transform
