Using FormattedText to create a Bitmap

Question

In a C# forms project, I can write the following code to get something like what I want, but it seems that there are two different "worlds" that I am trying to fuse.

FormattedText text = new FormattedText(textBox1.Text, CultureInfo.GetCultureInfo("en-us"), System.Windows.FlowDirection.LeftToRight, new Typeface("Tahoma"), 20, System.Windows.Media.Brushes.Black);
text.MaxTextWidth = 480;
text.MaxTextHeight = 480;
DrawingVisual d = new DrawingVisual();
DrawingContext d1 = d.RenderOpen();
d1.DrawText(text, new System.Windows.Point(0, 0));
d1.Close();
RenderTargetBitmap bmp = new RenderTargetBitmap(480, 480, 120, 96, PixelFormats.Pbgra32);
bmp.Render(d);
System.Windows.Controls.Image I=new System.Windows.Controls.Image();
I.Source = bmp;

Gets me a Windows.Media.ImageSource. I want to migrate the whole thing to use the System.Drawing namespace.

Since I basically had to import WPF libraries to make the above code work, and what I am looking to do is so basic, how can I do it in Windows Forms, preferably in a non-cludgy way.

Note: All I really want to do is draw text on a bitmap in a way that allows line wrapping, and then manipulate it as a bitmap. If there is a simpler way of doing that (in Windows Forms) that would work just as well, if not better.

Yes, that's WPF code, an entirely different world. The System.Drawing version ought to resemble something like this:

var bmp = new Bitmap(480, 480);
using (var gr = Graphics.FromImage(bmp)) {
    gr.Clear(Color.White);
    TextRenderer.DrawText(gr, textBox1.Text, this.Font, 
        new Rectangle(0, 0, bmp.Width, bmp.Height), 
        Color.Black, Color.White,
        TextFormatFlags.WordBreak | TextFormatFlags.Left);
}
if (pictureBox1.Image != null) pictureBox1.Image.Dispose();
pictureBox1.Image = bmp;

I guessed at a picture box on the form.
