Member Function Documentation

◆ GetCodePagesSupported()

virtual String [] iText.IO.Font.TrueTypeFont.GetCodePagesSupported ( )

inlinevirtual

Gets the code pages supported by the font.

Returns: the code pages supported by the font

◆ GetDirectoryOffset()

virtual int iText.IO.Font.TrueTypeFont.GetDirectoryOffset ( )

inlinevirtual

The offset from the start of the file to the table directory.

The offset from the start of the file to the table directory. It is 0 for TTF and may vary for TTC depending on the chosen font.

Returns: directory Offset

◆ GetKerning()

override int iText.IO.Font.TrueTypeFont.GetKerning	(	Glyph	first,
		Glyph	second
	)

inlinevirtual

Gets the kerning between two glyphs.

Parameters

first	the first glyph
second	the second glyph

Returns: the kerning to be applied

Implements iText.IO.Font.FontProgram.

◆ IsBuiltWith()

override bool iText.IO.Font.TrueTypeFont.IsBuiltWith ( String fontName )

inlinevirtual

Checks whether the FontProgram was built with corresponding fontName.

Checks whether the FontProgram was built with corresponding fontName. Default value is false unless overridden.

Parameters

fontName a font name or path to a font program

Returns: true, if the FontProgram was built with the fontProgram. Otherwise false.

Reimplemented from iText.IO.Font.FontProgram.

Reimplemented in iText.Kernel.Font.DocTrueTypeFont.

◆ MapGlyphsCidsToGids()

virtual ICollection iText.IO.Font.TrueTypeFont.MapGlyphsCidsToGids ( ICollection< int > glyphs )

inlinevirtual

Maps a set of glyph CIDs (as used in PDF file) to corresponding GID values (as a glyph primary identifier in the font file).

Maps a set of glyph CIDs (as used in PDF file) to corresponding GID values (as a glyph primary identifier in the font file). This call is only meaningful for fonts that return true for IsCff(). For other types of fonts, GID and CID are always the same, so that call would essentially return a set of the same values.

Parameters

glyphs a set of glyph CIDs

Returns: a set of glyph ids corresponding to the passed glyph CIDs

◆ UpdateUsedGlyphs()

virtual void iText.IO.Font.TrueTypeFont.UpdateUsedGlyphs	(	SortedSet< int >	usedGlyphs,
		bool	subset,
		IList< int[]>	subsetRanges
	)

inlinevirtual

The method will update usedGlyphs with additional range or with all glyphs if there is no subset.

The method will update usedGlyphs with additional range or with all glyphs if there is no subset. This set of used glyphs can be used for building width array and ToUnicode CMAP.

Parameters

usedGlyphs	a set of integers, which are glyph ids that denote used glyphs. This set is updated inside of the method if needed.
subset	subset status
subsetRanges	additional subset ranges

Member Data Documentation

◆ kerning

IntHashtable iText.IO.Font.TrueTypeFont.kerning = new IntHashtable()

package

The map containing the kerning information.

The map containing the kerning information. It represents the content of table 'kern'. The key is an Integer where the top 16 bits are the glyph number for the first character and the lower 16 bits are the glyph number for the second character. The value is the amount of kerning in normalized 1000 units as an Integer. This value is usually negative.
