Detailed Description

Aim: This class specializes a 'Board' class so as to display DGtal objects more naturally (with <<). The user has simply to declare a Board2D object and uses stream operators to display most digital objects. Furthermore, one can use this class to modify the current style for drawing.

◆ Shape

typedef LibBoard::Shape DGtal::Board2D::Shape

Definition at line 86 of file Board2D.h.

Constructor & Destructor Documentation

◆ ~Board2D()

DGtal::Board2D::~Board2D ( )

Destructor.

◆ Board2D() [1/2]

DGtal::Board2D::Board2D ( const Color & aBackgroundColor = Color::None )

Constructs a new board and sets the background color, if any.

Parameters

aBackgroundColor A color for the drawing's background.

References DGtal::Color::None.

Referenced by Board2D(), operator<<(), and operator=().

◆ Board2D() [2/2]

DGtal::Board2D::Board2D ( const Board2D & other )

Copy constructor.

Parameters

other The object to be copied.

References Board2D().

Member Function Documentation

◆ getMode()

std::string DGtal::Board2D::getMode ( const std::string & objectName ) const

Parameters

objectName the name of the object (generally obtained with a 'object.className()').

Returns: the current mode for the given object name or "" if no specific mode has been set.

◆ isValid()

bool DGtal::Board2D::isValid ( ) const

Checks the validity/consistency of the object.

Returns: 'true' if the object is valid, 'false' otherwise.

◆ operator<<()

template<typename TDrawableWithBoard2D>

Board2D & DGtal::Board2D::operator<< ( const TDrawableWithBoard2D & object )

Draws the drawable [object] in this board. It should satisfy the concept CDrawableWithBoard2D, which requires for instance a method setStyle( Board2D & ).

Parameters

object any drawable object.

Returns: a reference on 'this'.

References Board2D().

◆ operator=()

Board2D & DGtal::Board2D::operator= ( const Board2D & other )

Assignment.

Parameters

other the object to copy.

Returns: a reference on 'this'.

References Board2D().

◆ selfDisplay()

void DGtal::Board2D::selfDisplay ( std::ostream & out ) const

Writes/Displays the object on an output stream.

Parameters

out	the output stream where the object is written.

Field Documentation

◆ myModes

ModeMapping DGtal::Board2D::myModes

May associate a current mode for a given class. myModes[ "HyperRectDomain" ] = "Paving".

Next display of a HyperRectDomain object will used the mode "Paving". Modes may only be used in objects implementing the concept CDrawableWithBoard2D.

Definition at line 175 of file Board2D.h.

◆ myStyles

StyleMapping DGtal::Board2D::myStyles

For instance, may associate a new style object T1 to the class "HyperRectDomain": myStyles[ "HyperRectDomain" ] = T1.

One can also store a new style T2 for a specific mode used for drawing a class: myStyles[ "HyperRectDomain/Paving" ] = T2.

Modes may only be used in objects implementing the concept CDrawableWithBoard2D.
