new Matrix()
The Matrix class is now an object, which makes it a lot faster, here is a representation of it : | a | b | tx | | c | d | ty | | 0 | 0 | 1 |

Public Methods
-
append(matrix) → {PIXI.Matrix}
-
Appends the given Matrix to this Matrix.
Parameters
Name Type Description matrix
PIXI.Matrix -
Returns
This matrix. Good for chaining method calls.
- Source code: pixi/geom/Matrix.js, line 225
-
apply(pos, newPos) → {PIXI.Point}
-
Get a new position with the current transformation applied. Can be used to go from a child's coordinate space to the world coordinate space. (e.g. rendering)
Parameters
Name Type Argument Description pos
PIXI.Point The origin
newPos
PIXI.Point <optional>
The point that the new position is assigned to (allowed to be same as input)
Returns
The new point, transformed through this matrix
- Source code: pixi/geom/Matrix.js, line 123
-
applyInverse(pos, newPos) → {PIXI.Point}
-
Get a new position with the inverse of the current transformation applied. Can be used to go from the world coordinate space to a child's coordinate space. (e.g. input)
Parameters
Name Type Argument Description pos
PIXI.Point The origin
newPos
PIXI.Point <optional>
The point that the new position is assigned to (allowed to be same as input)
Returns
The new point, inverse-transformed through this matrix

-
fromArray(array)
-
Creates a Matrix object based on the given array. The Element to Matrix mapping order is as follows:
a = array[0] b = array[1] c = array[3] d = array[4] tx = array[2] ty = array[5]
Parameters
Name Type Description array
Array The array that the matrix will be populated from.

-
identity() → {PIXI.Matrix}
-
Resets this Matix to an identity (default) matrix.
Returns
This matrix. Good for chaining method calls.
- Source code: pixi/geom/Matrix.js, line 250
-
rotate(angle) → {PIXI.Matrix}
-
Applies a rotation transformation to the matrix.
Parameters
Name Type Description angle
Number The angle in radians.
Returns
This matrix. Good for chaining method calls.

-
scale(x, y) → {PIXI.Matrix}
-
Applies a scale transformation to the matrix.
Parameters
Name Type Description x
Number The amount to scale horizontally
y
Number The amount to scale vertically
Returns
This matrix. Good for chaining method calls.
- Source code: pixi/geom/Matrix.js, line 179
-
toArray(transpose) → {Array}
-
Creates an array from the current Matrix object.
Parameters
Name Type Description transpose
Boolean Whether we need to transpose the matrix or not
Returns
Array -the newly created array which contains the matrix

-
translate(x, y) → {PIXI.Matrix}
-
Translates the matrix on the x and y.
Parameters
Name Type Description x
Number -
y
Number -
Returns
This matrix. Good for chaining method calls.
