DOMMatrix: rotateSelf() method

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

rotY Optional

A number; the y-coordinate of the vector denoting the axis of rotation.

rotZ Optional

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)"
