◆ GetContextLength()

override int iText.IO.Font.Otf.Lookuptype5.SubTableLookup5Format1.SubstRuleFormat1.GetContextLength ( )

inlinevirtual

Gets the length of the context glyph sequence defined by this rule

Returns: length of the context

Implements iText.IO.Font.Otf.ContextualRule.

◆ GetSubstLookupRecords()

override SubstLookupRecord [] iText.IO.Font.Otf.Lookuptype5.SubTableLookup5Format1.SubstRuleFormat1.GetSubstLookupRecords ( )

inlinevirtual

Retrieves the substitution lookup records.

Retrieves the substitution lookup records. Each record specifies a position in the context glyph sequence and a LookupListIndex to the substitution lookup that is applied at that position.

Returns: an array of SubstLookupRecord.

Implements iText.IO.Font.Otf.ContextualSubstRule.

◆ IsGlyphMatchesInput()

override bool iText.IO.Font.Otf.Lookuptype5.SubTableLookup5Format1.SubstRuleFormat1.IsGlyphMatchesInput	(	int	glyphId,
		int	atIdx
	)

inlinevirtual

Checks if glyph line element matches element from input sequence of the rule.

Checks if glyph line element matches element from input sequence of the rule.

NOTE: rules do not contain the first element of the input sequence, the first element is defined by rule position in substitution table. Therefore atIdx shall not be 0.

Parameters

glyphId	glyph code id
atIdx	index in the rule sequence. Shall be: 0 < atIdx < GetContextLength()

Returns

true if glyph matches element

Implements iText.IO.Font.Otf.ContextualRule.
