makVrv::DtCharacterEncodingMap Class Reference

The character encoding map, maps the character code to a glyph index. Note there are two glyph indexes - the first is the container index, which is used in DtFont for vector access of a DtGlyph. This is stored against the character code in CharacterCodeToContainerIndexMap. The second is also the vector container index but this is keyed off the glyph index of the glyph inside the font, and stored in GlyphIndexToContainerIndexMap.
