C＃ - DrawString绘制文本翻转

Question

我正在使用带有自定义TabControl控件的主题。

控件使用DrawString方法为每个标签绘制文本，如下所示：

using (SolidBrush B = new SolidBrush(FC))
{
    G.DrawString(TabPages[i].Text, Theme.GlobalFont(FontStyle.Regular, 10), B, new Point(TabRect.X + 50, TabRect.Y + 12));
}

将文本更改为希伯来语，并将控件的RightToLeftLayout更改为true后，文本将翻转为：

我尝试在线搜索并发现您可以使用Transform来修改文本，但我相信情况并非如此，因为它应该是一项简单的任务。这是控件的完整类：

class FirefoxMainTabControl : TabControl
{

    #region " Private "
    private Graphics G;
    private Rectangle TabRect;
    #endregion
    private Color FC = Color.Blue;

    #region " Control "

    public FirefoxMainTabControl()
    {
        DoubleBuffered = true;
        ItemSize = new Size(43, 152);
        Alignment = TabAlignment.Left;
        SizeMode = TabSizeMode.Fixed;
    }

    protected override void OnCreateControl()
    {
        base.OnCreateControl();
        SetStyle(ControlStyles.UserPaint, true);
    }

    protected override void OnControlAdded(ControlEventArgs e)
    {
        base.OnControlAdded(e);
        try
        {
            for (int i = 0; i <= TabPages.Count - 1; i++)
            {
                TabPages[i].BackColor = Color.White;
                TabPages[i].ForeColor = Color.FromArgb(66, 79, 90);
                TabPages[i].Font = Theme.GlobalFont(FontStyle.Regular, 10);
            }
        }
        catch
        {
        }
    }


    protected override void OnPaint(PaintEventArgs e)
    {
        G = e.Graphics;
        G.SmoothingMode = SmoothingMode.HighQuality;
        G.TextRenderingHint = TextRenderingHint.ClearTypeGridFit;

        base.OnPaint(e);

        G.Clear(Color.FromArgb(66, 79, 90));


        for (int i = 0; i <= TabPages.Count - 1; i++)
        {
            TabRect = GetTabRect(i);


            if (SelectedIndex == i)
            {
                using (SolidBrush B = new SolidBrush(Color.FromArgb(52, 63, 72)))
                {
                    G.FillRectangle(B, TabRect);
                }

                FC = Helpers.GreyColor(245);

                using (SolidBrush B = new SolidBrush(Color.FromArgb(255, 175, 54)))
                {
                    G.FillRectangle(B, new Rectangle(TabRect.Location.X - 3, TabRect.Location.Y + 1, 5, TabRect.Height - 2));
                }

            }
            else
            {
                FC = Helpers.GreyColor(192);

                using (SolidBrush B = new SolidBrush(Color.FromArgb(66, 79, 90)))
                {
                    G.FillRectangle(B, TabRect);
                }

            }

            using (SolidBrush B = new SolidBrush(FC))
            {
                G.DrawString(TabPages[i].Text, Theme.GlobalFont(FontStyle.Regular, 10), B, new Point(TabRect.X + 50, TabRect.Y + 12));
            }

            if ((ImageList != null))
            {
                if (!(TabPages[i].ImageIndex < 0))
                {
                    G.DrawImage(ImageList.Images[TabPages[i].ImageIndex], new Rectangle(TabRect.X + 19, TabRect.Y + ((TabRect.Height / 2) - 10), 18, 18));
                }
            }

        }

    }
