A DOMRect represents a rectangle.

The type of box represented by the DOMRect is specified by the method or property that returned it. For example, VREyeParameters.renderRect from the WebVR API specifies the viewport of a canvas into which visuals for one eye of a head mounted display should be rendered.

It inherits from its parent, DOMRectReadOnly.


Creates a new DOMRect object.


DOMRect inherits properties from its parent, DOMRectReadOnly. The difference is that they are not read-only anymore.

The x coordinate of the DOMRect's origin.
The y coordinate of the DOMRect's origin.
The width of the DOMRect.
The height of the DOMRect.
Returns the top coordinate value of the DOMRect (has the same value as y, or y + height if height is negative.)
Returns the right coordinate value of the DOMRect (has the same value as x + width, or x if width is negative.)
Returns the bottom coordinate value of the DOMRect (has the same value as y + height, or y if height is negative.)
Returns the left coordinate value of the DOMRect (has the same value as x, or x + width if width is negative.)
