DOMQuad

A DOMQuad is a collection of four DOMPoints defining the corners of an arbitrary quadrilateral. Returning DOMQuads lets getBoxQuads() return accurate information even when arbitrary 2D or 3D transforms are present. It has a handy bounds attribute returning a DOMRectReadOnly for those cases where you just want an axis-aligned bounding rectangle.

Constructor

DOMQuad(): Creates a new DOMQuad object.

Instance properties

p1,p2,p3,p4 Read only: are DOMPoint objects for each of the DOMQuad object's four corners.

Instance methods

DOMQuad.fromRect(): Returns a new DOMQuad object based on the passed set of coordinates.
DOMQuad.fromQuad(): Returns a new DOMQuad object based on the passed set of coordinates.
DOMQuad.getBounds(): Returns a DOMRect object with the coordinates and dimensions of the DOMQuad object.
