Detailed Description

Basic PdfEncodingMap implementation using a PdfCharCodeMap

Member Function Documentation

appendBaseFontEntries()

void PdfEncodingMapBase::appendBaseFontEntries ( PdfStream &  stream ) const

overrideprotectedvirtual

During a WriteToUnicodeCMap append "beginbfchar" and "beginbfrange" entries "bf" stands for Base Font, see Adobe tecnichal notes #5014

Implements mm::PdfEncodingMap.

tryGetCharCode()

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

overrideprotectedvirtual

Try get char code unit from unicode code point

Implements mm::PdfEncodingMap.

tryGetCharCodeSpan()

bool PdfEncodingMapBase::tryGetCharCodeSpan ( const cspan< char32_t > &  ligature, PdfCharCode &  codeUnit  ) const

overrideprotectedvirtual

Try get next char code unit from a ligature

Parameters

ligature

the span has at least 2 unicode code points

Remarks

Default implementation just throws

Reimplemented from mm::PdfEncodingMap.

tryGetCodePoints()

bool PdfEncodingMapBase::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.

tryGetNextCharCode()

bool PdfEncodingMapBase::tryGetNextCharCode ( std::string_view::iterator &  it, const std::string_view::iterator &  end, PdfCharCode &  codeUnit  ) const

overrideprotectedvirtual

Try get next char code unit from a utf8 string range

Remarks

Default implementation just throws

Reimplemented from mm::PdfEncodingMap.
