Affine2dC
2-D affine transformation
include	"amma/Affine2d.hh"
User Level:	Default
Library:	Mag2
Example:	exMat2d.cc
Section:	Geometry.2-D
In Scope:	std

Comments:
This class is used to apply a (6-parameter) 2-D affine transformation. Note that it transforms the point w.r.t. the coordinate system; it does not transform the coordinate system itself.

public AffineC<class MatrixT,class VectorT>

Affine2dC()

Construct identity transformation.

Affine2dC(const AffineC<Matrix2d2C,Vector2dC> & Oth)

Construct from base template.

Affine2dC(const Affine2dC & Oth)

Copy constructor.

Affine2dC(const Matrix2d2C & SR,const Vector2dC & T)

Constructor from scaling/rotation matrix and translation vector.

Affine2dC(const Vector2dC & Scale,RealT Angle,const Vector2dC & Trans)

Constructor for arbitrary anisotropic scaling, rotation and translation.
The scaling axes are aligned with the coordinate axes.

Affine2dC(const Vector2dC & Scale,RealT ScaleAngle,RealT Angle,const Vector2dC & Trans)

Constructor for arbitrary anisotropic scaling, rotation and translation.
The scaling axes are aligned at an angle ScaleAngle w.r.t. the coordinate axes.

void Rotate(RealT Angle)

Add rotation Angle to transformation

Vector2dC & Translation()

Access the translation component of the transformation.

Vector2dC Translation() const

Constant access to the translation component of the transformation.

void Scale(Vector2dC xy)

In place Scaling along the X & Y axis by value given in the vector.
If all values 1, then no effect.

void Translate(const Vector2dC & T)

Add a translation in direction T.

Vector2dC operator*(const Vector2dC & In) const

Transform Vector, Scale, Rotate, Translate.
Take a vector and put it though the transformation.

AffineC<Matrix2d2C,Vector2dC> operator*(const AffineC & In) const

Compose this transform with 'In'

AffineC<Matrix2d2C,Vector2dC> operator/(const AffineC & In) const

'In' * 'Out' = this; returns 'Out'

AffineC<Matrix2d2C,Vector2dC> I(void) const

Generate an inverse transformation.

Matrix2d2C & SRMatrix()

Get Scale/Rotate matrix.

const Matrix2d2C & SRMatrix() const

Get Scale/Rotate matrix.

const AffineC<Matrix2d2C,Vector2dC> & operator=(const AffineC & Oth)

Assigmment.
