The DOMPointReadOnly
interface's w
property holds the point's perspective value, w, for a read-only point in space. If your script needs to be able to change the value of this property, you should instead use the DOMPoint
object.
var perspective = DOMPointReadOnly.w;
A double-precision floating-point value indicating the w perspective value for the point. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be NaN
or ±Infinity
). The default is 1.0.
