Script Reference : Rect

A Rect object stores the upper-left and lower-right corners of a rectangle. This is just a cordinates of rectange, there is no relation to content on the page.

Data Members
Name	Type	Description
left	float	Specifies the x-coordinate of the upper-left corner of the rectangle.
top	float	Specifies the y-coordinate of the upper-left corner of the rectangle.
right	float	Specifies the x-coordinate of the lower-right corner of the rectangle.
bottom	float	Specifies the y-coordinate of the lower-right corner of the rectangle.

Constructors
Name	Description
Rect::Rect()	Creates a Rect object whose left,top,bottom,right coordinates are all zero. This is the default constructor.
Rect::Rect(Rect)	Creates a new Rect object and copies the data members from another Rect object.
Rect::Rect(Point leftTop, Point rigthBottom)	Creates a new Rect object using left top and right bottom coordinates.
Rect::Rect(float left, float top, float right, float bottom)	Creates a new Rect object using left, top, bottom, right coordinates.

Methods
Name	Return Type	Description
bool Contains(Rect) bool Contains(Point) bool Contains(float x,float y)	bool	The Contains method determines whether another rectangle or point is inside this rectangle.
bool Intersect(Rect)	bool	If the intersection of the two rectangles is not empty, this method returns true; otherwise, it returns false.
void Offset(Point) void Offset(float x,float y)	void	The Offset method moves this rectangle horizontally and vertically.
void Inflate(Point) void Inflate(float x,float y)	void	The Inflate method expands the rectangle by the value of X on the left and right edges, and by the value of Y on the top and bottom edges.
Point Center()	Point	Returns center of this rectangle.
Point Size()	Point	The GetSize method gets the width and height of the rectangle.
void Normalize()	void	Normalizes rectangle by swapping left and right in case if left is greater than right. Same with ot top and bottom.
+= Rect += Point Rect + Rect		Operators enlarge this rectangle in case if specified area or point is outside of this rectangle.
bool IsEmpty()	bool	The IsEmpty method determines whether this rectangle is empty.
float Width()	float	Width of rectangle
float Height()	float	Height of rectangle

Sample:

local r=Rect(0,0,100,200);
local p=Point(-1,-2);
r+=p;
MsgBox("Rect: "+ r.left.tostring()+", "+r.top.tostring()+", "+r.right.tostring()+", "+r.bottom.tostring());
