Detailed Description

A common base class for built-in encodings which are known by name.

Member Function Documentation

GetName()

const PdfName & PoDoFo::PdfBuiltInEncoding::GetName ( ) const

inline

Get the name of this encoding.

Returns

the name of this encoding.

GetToUnicodeTable()

virtual const char32_t * PoDoFo::PdfBuiltInEncoding::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 PoDoFo::PdfMacExpertEncoding, PoDoFo::PdfMacRomanEncoding, PoDoFo::PdfStandardEncoding, PoDoFo::PdfSymbolEncoding, PoDoFo::PdfWinAnsiEncoding, and PoDoFo::PdfZapfDingbatsEncoding.

tryGetCharCode()

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

overrideprotectedvirtual

Try get char code unit from unicode code point

Implements PoDoFo::PdfEncodingMap.

tryGetCodePoints()

bool PdfBuiltInEncoding::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 PoDoFo::PdfEncodingMap.
