DOMMatrix: rotateSelf() method
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 rotateSelf() method of the DOMMatrix interface is a mutable transformation method that modifies a matrix. It rotates the source matrix around each of its axes by the specified number of degrees and returns the rotated matrix.
To rotate a matrix without mutating it, see DOMMatrixReadOnly.rotate()
Syntax
rotateSelf()
rotateSelf(rotX)
rotateSelf(rotX, rotY)
rotateSelf(rotX, rotY, rotZ)
Parameters
rotX-
A number; the x-coordinate of the vector denoting the axis of rotation
rotYOptional-
A number; the y-coordinate of the vector denoting the axis of rotation.
rotZOptional-
A number; the z-coordinate of the vector denoting the axis of rotation
If only one parameter is passed, rotZ is the value of rotX, and both rotX and rotY are 0, and the rotation is a 2D rotation. If rotX and rotY are non-zero, the is2D is false.
Return value
Returns itself; the DOMMatrix rotated by the given
vectors.
Examples
const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.toString()); // output: "matrix(1, 0, 0, 1, 0, 0)"
matrix.rotateSelf(30); // mutate it
console.log(matrix); // output: "matrix(0.866, 0.5, -0.5, 0.866, 0, 0)"
