DOMMatrixReadOnly: is2D property
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 readonly is2D property of the DOMMatrixReadOnly interface is a Boolean flag that is true when the matrix is 2D. The value is true if the matrix was initialized as a 2D matrix and only 2D transformation operations were applied. Otherwise, the matrix is defined in 3D, and is2D is false.
Value
A Boolean value.
Examples
js
// Initialize a 2D matrix
const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.is2D); // output: true
// Transform in a 2D space
console.log(matrix.rotate(30).is2D); // output: true
// Apply a 3D transform
console.log(matrix.rotate(10, 20, 1).is2D); // output: false
