Detailed Description
A NormalizedRect is a rectangle which can be defined by two NormalizedPoints.
It describes a rectangular area on a reference area of undefined size. For more information about the normalized coordinate system, see NormalizedPoint.
In Okular, NormalizedRect can be used e. g. to describe bounding boxes of TextEntity objects, and the highlight area of text selections.
If you need to describe an area which consists of multiple rectangles, you can use RegularAreaRect instead.

Constructor & Destructor Documentation
◆ NormalizedRect() [1/4]
NormalizedRect::NormalizedRect  (  ) 
◆ NormalizedRect() [2/4]
NormalizedRect::NormalizedRect  (  double  left, 
double  top,  
double  right,  
double  bottom  
) 
Creates a normalized rectangle with the normalized coordinates left
, top
, right
, bottom
.
If you need the x, y, width and height coordinates use the following formulas:
 x = left
 y = top
 width = right  left
 height = bottom  top
 Note
 The coordinates for
left
andtop
should be lower thanright
andbottom
, respectively. At negative width or height the behaviour of some operations is undefined.
◆ NormalizedRect() [3/4]
NormalizedRect::NormalizedRect  (  const QRect  rectangle, 
double  xScale,  
double  yScale  
) 
Creates a normalized rectangle from the given rectangle
on a reference area of size xScale
x yScale
.
 Note
 The rectangle should have positive width and height. You can use e. g. QRect::normalize() to ensure this. At negative width or height the behaviour of some operations is undefined.
