Syntax

public class TransformationMatrix

Constructors

TransformationMatrix()

Creates a new identity matrix instance.

Declaration

public TransformationMatrix()

Properties

Elements

Matrix elements in row-major order.

As the elements of the third column are always [ 0, 0, 1 ], only the first two columns are returned, i.e. 6 elements.

Declaration

public double[] Elements { get; }

Property Value

Type	Description
double[]

TranslationX

Gets the horizontal translation.

Declaration

public double TranslationX { get; }

Property Value

Type	Description
double

TranslationY

Gets the vertical translation.

Declaration

public double TranslationY { get; }

Property Value

Type	Description
double

Methods

Rotate(double)

Applies a rotation about the origin (prepend).

Declaration

public void Rotate(double angle)

Parameters

Type	Name	Description
double	angle	Rotation angle (in radians)

Scale(double, double)

Applies a scaling relative to the origin (prepend).

Declaration

public void Scale(double sx, double sy)

Parameters

Type	Name	Description
double	sx	horizontal scaling
double	sy	vertical scaling

Translate(double, double)

Applies a translation to the matrix (prepend).

Declaration

public void Translate(double dx, double dy)

Parameters

Type	Name	Description
double	dx	horizontal translation
double	dy	vertical translation
