Member Enumeration Documentation

◆ Orientation

This enumeration defines the possible values for the printing orientation.

mode of the IlvPrinter.

This mode defines if the printer will print in portrait or landscape.

Enumerator
Portrait 

The orientation is portrait.

Constructor & Destructor Documentation

◆ IlvPrinter()

IlvPrinter::IlvPrinter ( IlvDisplay display)

Constructor.

This is the constructor. It initializes the object in a coherent state. The default paper size is A4. The default paper mode is IlvPrinter::Printing. The default paper orientation is IlvPrinter::Portrait.

◆ ~IlvPrinter()

virtual IlvPrinter::~IlvPrinter ( )
virtual

Destructor.

The destructor actually does nothing, but it is declared as virtual so that inherited classes may overload it.
