DOMMatrixReadOnly: skewY() method

{{APIRef("Geometry Interfaces")}}{{AvailableInWorkers}}

The skewY() method of the {{domxref("DOMMatrixReadOnly")}} interface returns a new {{domxref("DOMMatrix")}} created by applying the specified skew transformation to the source matrix along its y-axis. The original matrix is not modified.

To mutate the matrix as you skew it along the y-axis, see {{domxref("DOMMatrix.skewYSelf()")}}.

Syntax

skewY()
skewY(sY)

Parameters

• sY
  • : A number; the angle, in degrees, by which to skew the matrix along the y-axis.

Return value

A DOMMatrix.

Examples

const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.toString()); // original value
// "matrix(1, 0, 0, 1, 0, 0)"

console.log(matrix.skewY(14).toString()); // skew along y-axis
// "matrix(1, -0.25, 0, 1, 0, 0)"

console.log(matrix.toString()); // original unchanged
// "matrix(1, 0, 0, 1, 0, 0)"
