FontDetails(PdfName fontName,
            PdfIndirectReference indirectReference,
            BaseFont baseFont)

Each font used in a document has an instance of this class. This class stores the characters used in the document and other specifics unique to the current working document.

Parameters:

fontName - the font name

indirectReference - the indirect reference to the font

baseFont - the BaseFont

Method Detail

getIndirectReference

PdfIndirectReference getIndirectReference()

Gets the indirect reference to this font.

Returns:

the indirect reference to this font

getFontName

PdfName getFontName()

Gets the font name as it appears in the document body.

Returns:

the font name

getBaseFont

BaseFont getBaseFont()

Gets the BaseFont of this font.

Returns:

the BaseFont of this font

convertToBytesGid

java.lang.Object[] convertToBytesGid(java.lang.String gids)

convertToBytes

byte[] convertToBytes(java.lang.String text)

Converts the text into bytes to be placed in the document. The conversion is done according to the font and the encoding and the characters used are stored.

Parameters:

text - the text to convert

Returns:

the conversion

canApplyGlyphSubstitution

private boolean canApplyGlyphSubstitution()

convertToBytesAfterGlyphSubstitution

private byte[] convertToBytesAfterGlyphSubstitution(java.lang.String text)

public void writeFont(PdfWriter writer)

Writes the font definition to the document.

Parameters:

writer - the PdfWriter of this document

isSubset

public boolean isSubset()

Indicates if all the glyphs and widths for that particular encoding should be included in the document.

Returns:

false to include all the glyphs and widths.

setSubset

public void setSubset(boolean subset)

Indicates if all the glyphs and widths for that particular encoding should be included in the document. Set to false to include all.
