LocalizedStrings_NameTable()

SkOTUtils::LocalizedStrings_NameTable::LocalizedStrings_NameTable ( std::unique_ptr< uint8_t[]>  nameTableData, size_t  size, SK_OT_USHORT  types[], int  typesCount  )

inline

Takes ownership of the nameTableData and will free it with SK_DELETE.

Member Function Documentation

Make()

sk_sp< SkOTUtils::LocalizedStrings_NameTable > SkOTUtils::LocalizedStrings_NameTable::Make ( const SkTypeface &  typeface, SK_OT_USHORT  types[], int  typesCount  )

static

Creates an iterator over all data in the 'name' table of a typeface. If no valid 'name' table can be found, returns nullptr.

Definition at line 170 of file SkOTUtils.cpp.

{
    static const SkFontTableTag nameTag = SkSetFourByteTag('n','a','m','e');
    size_t nameTableSize = typeface.getTableSize(nameTag);
    if (0 == nameTableSize) {
        return nullptr;
    }
    std::unique_ptr<uint8_t[]> nameTableData(new uint8_t[nameTableSize]);
    size_t copied = typeface.getTableData(nameTag, 0, nameTableSize, nameTableData.get());

}

MakeForFamilyNames()

sk_sp< SkOTUtils::LocalizedStrings_NameTable > SkOTUtils::LocalizedStrings_NameTable::MakeForFamilyNames ( const SkTypeface &  typeface )

static

Creates an iterator over all the family names in the 'name' table of a typeface. If no valid 'name' table can be found, returns nullptr.

Definition at line 191 of file SkOTUtils.cpp.

                                                                                  {

}

next()

bool SkOTUtils::LocalizedStrings_NameTable::next ( SkTypeface::LocalizedString *  localizedString )

overridevirtual

Implements SkTypeface::LocalizedStrings.
