在Qt中整合freetype

建立字型對照表

    QSettings settings("HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Fonts",
                       QSettings::NativeFormat);
    QStringList list = settings.allKeys();

    for(int i=0;i<list.size();i++)
    {
        QString key = list.at(i);
        QString text = settings.value(key).toString();
        QStringList keys = key.split(" & ");
        QString last = keys.last();
        keys[keys.size()-1] = last.left(last.indexOf(" ("));
        for(int j=0;j<keys.size();j++)
        {
            index.insert(keys[j], j);
            name.insert(keys[j], text);
        }
    }

轉換成FT_Face

    QString family = ui->fontComboBox->currentText();
    QString path("C:/WINDOWS/Fonts/");
    path.append(name[family]);
    int in = index[family];
    FT_New_Face(library, path.toUtf8(), in, &face))
