DOMPointReadOnly

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

Constructor

DOMPointReadOnly()
Defined to create a new DOMPointReadOnly object, but note that this constructor cannot be called by 3rd party JavaScript: doing so returns an "Illegal constructor" typeError.

Methods

DOMPointReadOnly.fromPoint
Translates the position/perspective of a DOMPoint to a new position (doesn't appear to be supported anywhere yet.)
DOMPointReadOnly.matrixTransform
Applies a matrix transform to a DOMPointReadOnly object (doesn't appear to be supported anywhere yet.)
DOMPointReadOnly.toJSON()
Returns a JSON representation of the DOMPointReadOnly object.

Properties

DOMPointReadOnly.x Read only
The x coordinate of the DOMPoint.
DOMPointReadOnly.y Read only
The y coordinate of the DOMPoint.
DOMPointReadOnly.z Read only
The z coordinate of the DOMPoint.
DOMPointReadOnly.w Read only
