DOMQuad: p1 property

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

The DOMQuad interface's p1 property holds the {{domxref("DOMPoint")}} object that represents one of the four corners of the DOMQuad. When created from {{domxref("DOMQuad.fromRect_static", "DOMQuad.fromRect()")}}, it is the point (x, y).

Value

The {{domxref("DOMPoint")}} object includes the following double-precision floating-point values:

• {{domxref("DOMPoint.x")}}: The horizontal coordinate.
• {{domxref("DOMPoint.y")}}: The vertical coordinate.
• {{domxref("DOMPoint.z")}}: The depth coordinate.
• {{domxref("DOMPoint.w")}}: The perspective value. The default value is 1.0.

Each of these values is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be {{jsxref("NaN")}} or {{jsxref("Infinity", "±Infinity")}}).
