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

void Dummy(void)

Dummy function.

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)
