Member Function Documentation

getExportObject()

void PdfPredefinedEncoding::getExportObject ( PdfIndirectObjectList &  objects, PdfName &  name, PdfObject *&  obj  ) const

overrideprotectedvirtual

Get an export object that will be used during font init

Remarks

Default implementation just throws

Reimplemented from mm::PdfEncodingMap.

Reimplemented in mm::PdfWinAnsiEncoding.

GetName()

const PdfName & mm::PdfPredefinedEncoding::GetName ( ) const

inlineprotected

Get the name of this encoding.

Returns

the name of this encoding.

GetToUnicodeTable()

virtual const char32_t * mm::PdfPredefinedEncoding::GetToUnicodeTable ( ) const

protectedpure virtual

Gets a table of 256 short values which are the big endian Unicode code points that are assigned to the 256 values of this encoding.

This table is used internally to convert an encoded string of this encoding to and from Unicode.

Returns

an array of 256 big endian Unicode code points

Implemented in mm::PdfWinAnsiEncoding, mm::PdfMacRomanEncoding, mm::PdfMacExpertEncoding, mm::PdfDocEncoding, mm::PdfStandardEncoding, mm::PdfSymbolEncoding, mm::PdfZapfDingbatsEncoding, mm::PdfWin1250Encoding, and mm::PdfIso88592Encoding.

tryGetCharCode()

bool PdfPredefinedEncoding::tryGetCharCode ( char32_t  codePoint, PdfCharCode &  codeUnit  ) const

overrideprotectedvirtual

Try get char code unit from unicode code point

Implements mm::PdfEncodingMap.

tryGetCodePoints()

bool PdfPredefinedEncoding::tryGetCodePoints ( const PdfCharCode &  codeUnit, std::vector< char32_t > &  codePoints  ) const

overrideprotectedvirtual

Get code points from a code unit

Parameters

wantCID

true requires mapping to CID identifier, false for Unicode code points

Implements mm::PdfEncodingMap.
