Constructor & Destructor Documentation

BidiOrder() [1/3]

iTextSharp.text.pdf.BidiOrder.BidiOrder

(

sbyte[]

types

)

Initialize using an array of direction types. Types range from TYPE_MIN to TYPE_MAX inclusive and represent the direction codes of the characters in the text.

Parameters

types

the types array

BidiOrder() [2/3]

iTextSharp.text.pdf.BidiOrder.BidiOrder	(	sbyte[]	types,
		sbyte	paragraphEmbeddingLevel
	)

Initialize using an array of direction types and an externally supplied paragraph embedding level. The embedding level may be -1, 0, or 1. -1 means to apply the default algorithm (rules P2 and P3), 0 is for LTR paragraphs, and 1 is for RTL paragraphs.

Parameters

types	the types array
paragraphEmbeddingLevel	the externally supplied paragraph embedding level.

BidiOrder() [3/3]

iTextSharp.text.pdf.BidiOrder.BidiOrder	(	char[]	text,
		int	offset,
		int	length,
		sbyte	paragraphEmbeddingLevel
	)

Member Function Documentation

GetBaseLevel()

sbyte iTextSharp.text.pdf.BidiOrder.GetBaseLevel

(

)

Return the base level of the paragraph.

GetDirection()

static sbyte iTextSharp.text.pdf.BidiOrder.GetDirection ( char  c )

static

GetLevels() [1/2]

byte [] iTextSharp.text.pdf.BidiOrder.GetLevels

(

)

GetLevels() [2/2]

byte [] iTextSharp.text.pdf.BidiOrder.GetLevels

(

int[]

linebreaks

)

Return levels array breaking lines at offsets in linebreaks.
Rule L1.

The returned levels array contains the resolved level for each bidi code passed to the constructor.

The linebreaks array must include at least one value. The values must be in strictly increasing order (no duplicates) between 1 and the length of the text, inclusive. The last value must be the length of the text.

Parameters

linebreaks

the offsets at which to break the paragraph

Returns

the resolved levels of the text
