Detailed Description

PdfIdentityEncoding is a two-byte encoding which can be used with TrueType fonts to represent all characters present in a font. If the font contains all unicode glyphs, PdfIdentityEncoding will support all unicode characters.

Constructor & Destructor Documentation

Member Function Documentation

AppendCIDMappingEntries()

void PdfIdentityEncoding::AppendCIDMappingEntries ( OutputStream & stream, const PdfFont & font, charbuff & temp ) const

overrideprotectedvirtual

During a PdfEncoding::ExportToFont() append "begincidchar" and/or "begincidrange" entries. See Adobe tecnichal notes #5014\

To be called by PdfEncoding

Implements PoDoFo::PdfEncodingMap.

AppendToUnicodeEntries()

void PdfIdentityEncoding::AppendToUnicodeEntries ( OutputStream & stream, charbuff & temp ) const

overrideprotectedvirtual

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

To be called by PdfEncoding

Implements PoDoFo::PdfEncodingMap.

getExportObject()

void PdfIdentityEncoding::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 PoDoFo::PdfEncodingMap.

tryGetCharCode()

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

overrideprotectedvirtual

Try get char code unit from unicode code point

Implements PoDoFo::PdfEncodingMap.

tryGetCodePoints()

bool PdfIdentityEncoding::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.
