Ok make a new windows Form, then add a RichTextBox to it. Then render
your RTF on the richtextbox and screen dump the Form (you never have to
show it)

Here is the code to dump a Form:

public static void CaptureScreen(Form form, string saveLocation)
        {
            Graphics g1 = form.CreateGraphics();
            Image image = new Bitmap(form.ClientRectangle.Width,
form.ClientRectangle.Height, g1);
            Graphics g2 = Graphics.FromImage(image);
            IntPtr dc1 = g1.GetHdc();
            IntPtr dc2 = g2.GetHdc();
            BitBlt(dc2, 0, 0, form.ClientRectangle.Width,
form.ClientRectangle.Height, dc1, 0, 0, 13369376);
            g1.ReleaseHdc(dc1);
            g2.ReleaseHdc(dc2);
            image.Save(saveLocation, System.Drawing.Imaging.ImageFormat.Jpeg);   
            image.Dispose();
        }

[System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")]
        private  static extern  bool  BitBlt(
            IntPtr hdcDest, // handle to destination DC
            int nXDest, // x-coord of destination upper-left corner
            int nYDest, // y-coord of destination upper-left corner
            int nWidth, // width of destination rectangle
            int nHeight, // height of destination rectangle
            IntPtr hdcSrc, // handle to source DC
            int nXSrc, // x-coordinate of source upper-left corner
            int nYSrc, // y-coordinate of source upper-left corner
            System.Int32 dwRop // raster operation code
            );
