The rotate() method of the DOMMatrixReadOnly interface returns a new DOMMatrix created by rotating the source matrix around each of its axes by the specified number of degrees. The original matrix is not altered.
To mutate the matrix as you rotate it, see DOMMatrix.rotateSelf().
rotate()
rotate(rotX)
rotate(rotX, rotY)
rotate(rotX, rotY, rotZ)
rotX
A number; the x-coordinate of the vector denoting the axis of rotation. If non-zero, is2D is false.
rotY Optional
A number; the y-coordinate of the vector denoting the axis of rotation. If non-zero, is2D is false.
rotZ Optional
A number; the z-coordinate of the vector denoting the axis of rotation.
If only rotX is passed, then rotX is used as the value for the z-coordinate, and the x- and -y-coordinates are both set to zero.
A DOMMatrix.
const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.toString());
// output: "matrix(1, 0, 0, 1, 0, 0)"
const rotated = matrix.rotate(30); // rotation and assignment
console.log(matrix.toString()); // original matrix is unchanged
// output: "matrix(1, 0, 0, 1, 0, 0)"
console.log(rotated.toString());
// output: "matrix(0.866, 0.5, -0.5, 0.866, 0, 0)"
