Graphics.Drawstring 在 PictureBox 中看起来不错，但在 Bitmap 中却很糟糕

我正在尝试使用DrawString将文本写为图像，然后将其旋转 90 度。它无论是在位图上还是直接在 PictureBox 上都可以正常工作，但最大的区别在于质量。这PictureBox绘制的文本质量很好而且看起来很漂亮。当我把它画在图像上时，它看起来很可怕而且是块状的。我做了一些改变，试图让它看起来更好，但它看起来并不像应有的那么好。

示例代码：

使用 Windows 窗体项目并在其上放置 2 个图片框和一个按钮，然后使用以下代码运行它以了解我的意思：

Public Class Form1
   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

       Dim g As System.Drawing.Graphics
       g = PictureBox1.CreateGraphics

       ' x.DrawRectangle(New Pen(Brushes.White, 200), New Rectangle(0, 0, 200, 200))
       g.TranslateTransform(10.0F, 0.0F)
       g.RotateTransform(90)
       g.DrawString("MM Components", New Font("Arial", 7, FontStyle.Regular), Brushes.DarkBlue, New PointF(0, 0))

       Dim g2 As System.Drawing.Graphics
       Dim img As New Bitmap(300, 300, Drawing.Imaging.PixelFormat.Format24bppRgb)
       g2 = Graphics.FromImage(img)

       g2.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
       g2.TextRenderingHint = Drawing.Text.TextRenderingHint.AntiAliasGridFit
       g2.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
       ' img.SetResolution(150, 150)

       ' x.DrawRectangle(New Pen(Brushes.White, 200), New Rectangle(0, 0, 200, 200))
       g2.TranslateTransform(10.0F, 0.0F)
       g2.RotateTransform(90)
       g2.FillRectangle(Brushes.White, 0, 0, 300, 300)
       g2.DrawString("MM Components", New Font("Arial", 7, FontStyle.Regular), Brushes.DarkBlue, New PointF(0, 0))
       PictureBox2.Image = img

      'System.Threading.Thread.Sleep(20)
   End Sub
End Class

这些改变似乎让它看起来很不错......

    g2.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
    g2.TextRenderingHint = Drawing.Text.TextRenderingHint.ClearTypeGridFit
    g2.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
