The `DOMMatrixReadOnly`

interface represents 4x4 matrices, suitable for 2D and 3D operations. If this interface defines only read-only matrices, the `DOMMatrix`

interface which inherits from it, add all the properties and the methods to allow to have modifiable matrices.

### Variables

Are `double`

representing each component of a 4x4 matrix needed for 2D rotations and translations. They are aliases for some components of the 4x4 matrix:

`a` |
`m11` |

`b` |
`m12` |

`c` |
`m21` |

`d` |
`m22` |

`e` |
`m41` |

`f` |
`m42` |

`DOMMatrix`

aren't.Are `double`

representing each component of a 4x4 matrix. They are read-only, but their counterpart, with the same name, in `DOMMatrix`

aren't.

### Methods

`rotate (angle:Float, originX:Float = 0.0, originY:Float = 0.0):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the original matrix being rotated by the given angle, with the rotation centered on the origin given. The original matrix is not modified.

`rotateAxisAngle (x:Float, y:Float, z:Float, angle:Float):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the original matrix being rotated by the given angle and the give vector. The original matrix is not modified.

`rotateFromVector (x:Float, y:Float):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the original matrix being rotated by the angle between the given vector and (1,0), centered on the origin given. The original matrix is not modified.

`scale (scale:Float, originX:Float = 0.0, originY:Float = 0.0):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the matrix x and y dimensions being scaled by the given factor, centered on the origin given. The original matrix is not modified.

`scale3d (scale:Float, originX:Float = 0.0, originY:Float = 0.0, originZ:Float = 0.0):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the matrix x, y and z dimension being scaled by the given factor, centered on the origin given. The original matrix is not modified.

`scaleNonUniform (scaleX:Float, scaleY:Float = 1.0, scaleZ:Float = 1.0, originX:Float = 0.0, originY:Float = 0.0, originZ:Float = 0.0):DOMMatrix`

Returns a `DOMMatrix`

containing a new matrix being the result of the matrix x, y and z dimension being scaled by the given factor for each dimension, centered on the origin given. The original matrix is not modified.

Returns a `DOMMatrix`

containing a new matrix being the result of the original matrix being skewed along the x-axis by the given factor. The original matrix is not modified.

Returns a `DOMMatrix`

containing a new matrix being the result of the original matrix being skewed along the y-axis by the given factor. The original matrix is not modified.

`transformPoint (?point:DOMPointInit):DOMPoint`

Returns a `DOMPoint`

that is the point given in parameter multiplied by the matrix. Bot the original point and the matrix aren't modified.
