Bidirectional Attributes

These attributes, defined in the <ilviews/bidi/type.h> header file, are represented by five different enumeration types with various possible values, shown in Table 1.1. These values are used to retrieve the visual string that will be displayed from the stored logical string.

Table 1.1 Enumerations of Bidirectional Attributes
Bidirectional Attribute	Enumeration
IlvLayoutDirection	typedef enum IlvLayoutDirection { IlvLayoutDirectionLeftToRight, IlvLayoutDirectionRightToLeft, IlvLayoutDirectionContextual };
IlvNumerals	typedef enum IlvNumerals { IlvNumeralsNominal, IlvNumeralsNational, IlvNumeralsContextual };
IlvShaping	typedef enum IlvShaping { IlvShapingOff, IlvShapingOn };
IlvSwapping	typedef enum IlvSwapping { IlvSwappingOff, IlvSwappingOn };
IlvWordBreak	typedef enum IlvWordBreak { IlvWordBreakOff, IlvWordBreakOn };

These types and their impact on the shaping of character strings in Arabic or on the objects in which these strings appear are described further in the designated sections.
