System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(image);

System.Drawing.SizeF sf = g.MeasureString(text, drawFont, 1024); // Set up the 1 The width of the display  
image = new System.Drawing.Bitmap(image, new System.Drawing.Size(Convert.ToInt32(sf.Width), Convert.ToInt32(sf.Height)));
g = System.Drawing.Graphics.FromImage(image);

g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;
g.DrawString(text, drawFont, System.Drawing.Brushes.Black, new System.Drawing.RectangleF(new System.Drawing.PointF(0, 0), sf));
