Interface DOMPointReadOnly

The DOMPointReadOnly interface specifies the coordinate and perspective fields used by DOMPoint to define a 2D or 3D point in a coordinate system.

MDN Reference

interface DOMPointReadOnly {
    w: number;
    x: number;
    y: number;
    z: number;
    matrixTransform(matrix?: DOMMatrixInit): DOMPoint;
    toJSON(): any;
}

w x y z
matrixTransform toJSON
w: number

The DOMPointReadOnly interface's w property holds the point's perspective value, w, for a read-only point in space.

MDN Reference

x: number

The DOMPointReadOnly interface's x property holds the horizontal coordinate, x, for a read-only point in space. This property cannot be changed by JavaScript code in this read-only version of the DOMPoint object.

MDN Reference

y: number

The DOMPointReadOnl**y** interface's y property holds the vertical coordinate, y, for a read-only point in space.

MDN Reference

z: number

The DOMPointReadOnly interface's z property holds the depth coordinate, z, for a read-only point in space.

MDN Reference

  • The matrixTransform() method of the DOMPointReadOnly interface applies a matrix transform specified as an object to the DOMPointReadOnly object, creating and returning a new DOMPointReadOnly object. Neither the matrix nor the point are altered.

    Parameters

    Returns DOMPoint

  • The DOMPointReadOnly method toJSON() returns an object giving the JSON form of the point object.

    Returns any
