Examples
Creating a rectangular quad
This example creates a DOMQuad from scratch that happens to be rectangular. Using fromRect() is more convenient than using the DOMQuad() constructor.
js
const quad = DOMQuad.fromRect({ x: 10, y: 20, width: 100, height: 50 });
console.log(quad.p1); // DOMPoint {x: 10, y: 20, z: 0, w: 1}
console.log(quad.p2); // DOMPoint {x: 110, y: 20, z: 0, w: 1}
console.log(quad.p3); // DOMPoint {x: 110, y: 70, z: 0, w: 1}
console.log(quad.p4); // DOMPoint {x: 10, y: 70, z: 0, w: 1}
Creating a quad from DOMRect
This example shows how to create a DOMQuad from a DOMRect object.
js
const domRect = new DOMRect(50, 60, 200, 100);
const quad = DOMQuad.fromRect(domRect);
console.log(quad.p1); // DOMPoint {x: 50, y: 60, z: 0, w: 1}
console.log(quad.p2); // DOMPoint {x: 250, y: 60, z: 0, w: 1}
console.log(quad.p3); // DOMPoint {x: 250, y: 160, z: 0, w: 1}
console.log(quad.p4); // DOMPoint {x: 50, y: 160, z: 0, w: 1}
