DOMMatrixReadOnly: inverse() 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 inverse() method of the DOMMatrixReadOnly interface creates a new matrix which is the inverse of the original matrix. If the matrix cannot be inverted, the new matrix's components are all set to NaN and its is2D property is set to false. The original matrix is not changed.

To mutate the matrix as you invert it, see DOMMatrix.invertSelf().

Syntax

js
  DOMMatrixReadOnly.inverse()

Return value

A DOMMatrix.

Examples

js
const matrix = new DOMMatrixReadOnly().rotate(30);
const invertedMatrix = matrix.inverse();
console.log(matrix.toString());
// output: matrix(0.866, 0.5, -0.5, 0.866, 0, 0)
console.log(invertedMatrix.toString());
// output: matrix(0.866, -0.5, 0.5, 0.866, 0, 0)
