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 ( )

Creates a null normalized rectangle.

class NormalizedRect

See also
isNull()

Definition at line 117 of file area.cpp.

◆ 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 and top should be lower than right and bottom, respectively. At negative width or height the behaviour of some operations is undefined.

Definition at line 125 of file area.cpp.

◆ 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.

Definition at line 134 of file area.cpp.

◆ NormalizedRect() [4/4]

NormalizedRect::NormalizedRect ( const NormalizedRect & )
default

Member Function Documentation

◆ center()

NormalizedPoint NormalizedRect::center ( ) const

Returns the center of the rectangle.

Since
0.10 (KDE 4.4)

Definition at line 220 of file area.cpp.

◆ contains()

bool NormalizedRect::contains ( double x,
double y ) const

Returns whether the normalized rectangle contains the normalized point (x, y).

Definition at line 160 of file area.cpp.

◆ distanceSqr()

double Okular::NormalizedRect::distanceSqr ( double x,
double y,
double xScale,
double yScale ) const
inline

Returns the squared distance of the normalized point (x, y) to the closest edge, or 0 if the point is within the rectangle; using a reference area of size xScale x yScale.

Since
0.17 (KDE 4.11)

Definition at line 387 of file area.h.

◆ fromQRectF()

NormalizedRect NormalizedRect::fromQRectF ( const QRectF & rect)
static

Build a normalized rect from a QRectF, which already has normalized coordinates.

Definition at line 144 of file area.cpp.

◆ geometry()

QRect NormalizedRect::geometry ( int xScale,
int yScale ) const

Returns the rectangle mapped to a reference area of xScale x yScale.

Definition at line 232 of file area.cpp.

◆ geometryF()

QRectF NormalizedRect::geometryF ( float xScale,
float yScale ) const

Same functionality as geometry, but nothing is converted into int.

Definition at line 246 of file area.cpp.

◆ height()

double Okular::NormalizedRect::height ( ) const
inline
Since
1.4

Definition at line 412 of file area.h.

◆ intersects() [1/3]

bool NormalizedRect::intersects ( const NormalizedRect & other) const

Returns whether the normalized rectangle intersects the other normalized rectangle.

Definition at line 165 of file area.cpp.

◆ intersects() [2/3]

bool NormalizedRect::intersects ( const NormalizedRect * other) const

This is an overloaded member function, provided for convenience.

It behaves essentially like the above function.

Definition at line 170 of file area.cpp.

◆ intersects() [3/3]

bool NormalizedRect::intersects ( double left,
double top,
double right,
double bottom ) const

Returns whether the normalized rectangle intersects an other normalized rectangle, which is defined by left, top, right and bottom.

Definition at line 175 of file area.cpp.

◆ isBottom()

bool Okular::NormalizedRect::isBottom ( const NormalizedPoint & pt) const
inline

Returns true if the point pt is located below the bottom of the rectangle.

Definition at line 331 of file area.h.

◆ isBottomOrLevel()

bool Okular::NormalizedRect::isBottomOrLevel ( const NormalizedPoint & pt) const
