Transform class

Represents linear 2D transformation.

Members

var m00: Float;
var m01: Float;
var m02: Float;
var m10: Float;
var m11: Float;
var m12: Float;


These represent the values of the transformation matrix. The first number is row and the second is column.

Initialization

static function create(): Transform

Creates an identity transform.

Operations

function reset()

Resets back to identity transform.

function mul(tr: Transform)

Multiplies this transform with another.

function mul(tr1: Transform, tr2: Transform)

Stores multiplication of two transforms.

function invert()

Inverts this transform.

function invert(tr: Transform)

Stores invertion of another transform.

function translate(tx: Float, ty: Float)

Multiplies this transform with translation transform.

function rotate(angle: Float)

Multiplies this transform with rotate transform.

function scale(scale: Float)
function scale(sx: Float, sy: Float)

Multiplies this transform with scale transform.

function shear(sx: Float, sy: Float)

Multiplies this transform with shear transform.

function transform_x(x: Float, y: Float): Float
function transform_y(x: Float, y: Float): Float

Returns transformed X and Y coordinates.
