Public Member Functions
bool	isEmpty () const
	Returns true if width or height is zero.
RectI	toIntersected (const RectI &rect) const
	Returns the intersection of this rect and another, or an empty rect if they do not overlap.
bool	contains (const PointI &p) const
	Returns true if the given point is inside or on the edge of this rect.
bool	contains (const RectI &r) const
	Returns true if the given rect is entirely inside this rect.
bool	intersects (const RectI &r) const
	Returns true if this rect overlaps with the given rect.
PointI	center () const
	Returns the center point of this rect.
void	normalize ()
	Normalizes this rect so that width and height are non-negative.
RectI	toNormalized () const
	Returns a normalized copy of this rect.

Static Public Member Functions
static RectI	fromLTRB (Int left, Int top, Int right, Int bottom)
	Creates a rect from left, top, right, and bottom edges.
static RectI	fromXYWH (Int x, Int y, Int w, Int h)
	Creates a rect from x, y, width, and height.

Detailed Description

RectI is the integer counterpart of Rect: a PointI origin and a SizeI. Image regions and rounded drawing rectangles use this type. Widen it to Rect when a painter needs a floating-point rectangle.

Geometry matches Rect, including exclusive right and bottom edges in contains(). There is no rounding API on this type: rounding is how a Rect becomes a RectI.
