Detailed Description

template<class NormalizedShape, class Shape>
class Okular::RegularArea< NormalizedShape, Shape >

An area with normalized coordinates, consisting of NormalizedShape objects.

This is a template class to describe an area which consists of multiple shapes of the same type, intersecting or non-intersecting. The coordinates are normalized, and can be mapped to a reference area of defined size. For more information about the normalized coordinate system, see NormalizedPoint.

Class NormalizedShape must have the following functions/operators defined:

  • bool contains( double, double ), whether it contains the given NormalizedPoint
  • bool intersects( NormalizedShape )
  • bool isNull()
  • Shape geometry( int, int ), which maps to the reference area
  • operator|=( NormalizedShape ), which unites two NormalizedShape's

Member Function Documentation

◆ appendArea()

template<class NormalizedShape , class Shape >
void Okular::RegularArea< NormalizedShape, Shape >::appendArea ( const RegularArea< NormalizedShape, Shape > *  area)

Appends the given area to this area.

Definition at line 802 of file area.h.

◆ appendShape()

template<class NormalizedShape , class Shape >
void Okular::RegularArea< NormalizedShape, Shape >::appendShape ( const NormalizedShape &  shape,
MergeSide  side = MergeAll 
)

Appends the given shape to this area.

Definition at line 810 of file area.h.

◆ contains() [1/2]

template<class NormalizedShape , class Shape >
bool Okular::RegularArea< NormalizedShape, Shape >::contains ( const NormalizedShape &  shape) const

Returns whether this area contains a NormalizedShape object that equals shape.

Note
The original NormalizedShape objects can be lost if simplify() was called.

Definition at line 882 of file area.h.

◆ contains() [2/2]

template<class NormalizedShape , class Shape >
bool Okular::RegularArea< NormalizedShape, Shape >::contains ( double  x,
double  y 
) const

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

Definition at line 866 of file area.h.

◆ geometry()

template<class NormalizedShape , class Shape >
QList< Shape > Okular::RegularArea< NormalizedShape, Shape >::geometry ( int  xScale,
int  yScale,
int  dx = 0,
int  dy = 0 
) const

Returns the subareas of this regular area mapped to a reference area of size xScale x yScale, then translated by dx and dy.

Definition at line 891 of file area.h.

◆ intersects() [1/2]

template<class NormalizedShape , class Shape >
bool Okular::RegularArea< NormalizedShape, Shape >::intersects ( const NormalizedShape &  shape) const

Returns whether the regular area intersects with the given shape.

Definition at line 767 of file area.h.

◆ intersects() [2/2]

template<class NormalizedShape , class Shape >
bool Okular::RegularArea< NormalizedShape, Shape >::intersects ( const RegularArea< NormalizedShape, Shape > *  area) const

Returns whether this area intersects with the given area.

Definition at line 783 of file area.h.

◆ isNull()

template<class NormalizedShape , class Shape >
bool Okular::RegularArea< NormalizedShape, Shape >::isNull

Returns whether the regular area is a null area.

Definition at line 751 of file area.h.

◆ simplify()

template<class NormalizedShape , class Shape >
void Okular::RegularArea< NormalizedShape, Shape >::simplify

Simplifies this regular area by merging its intersecting subareas.

This might change the effective geometry of this area.

Definition at line 730 of file area.h.

◆ transform()

template<class NormalizedShape , class Shape >
void Okular::RegularArea< NormalizedShape, Shape >::transform ( const QTransform matrix)

Transforms the regular area with the operations defined by matrix.

Definition at line 909 of file area.h.
