DOMMatrixReadOnly: DOMMatrixReadOnly() constructor
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
Note: This feature is available in Web Workers.
The DOMMatrixReadOnly
constructor creates a new
DOMMatrixReadOnly
object which represents 4x4 matrices, suitable for 2D
and 3D operations.
Syntax
js
DOMMatrixReadOnly()
DOMMatrixReadOnly(init)
Parameters
init
Optional-
Either a string containing a sequence of numbers or an array of numbers specifying the matrix you want to create.
In case an array of numbers is passed, the behavior depends on the length of the array:
- for a 6-element array of components in the form
[a, b, c, d, e, f]
, a 2D read-only matrix is created, initialized with the provided components. - for a 16-element array of components (in the column-major order) in the form
[m11, m12, m13, …, m42, m43, m44]
, a 3D read-only matrix is created, initialized with the provided components.
- for a 6-element array of components in the form
