Bitmap bmp = new Bitmap(1000, 1000);
Font font = new Font("Arial", 10);
using (Graphics g = Graphics.FromImage(bmp))
 {
   g.Clear(System.Drawing.Color.White);
 }
using (Graphics g = Graphics.FromImage(bmp))
{
  g.DrawString("TEKST", font, System.Drawing.Brushes.Black, 0,0); 
}

Font font = new Font("Arial", 10, FontStyle.Bold);

Font font = new Font("Arial", 16.0f, FontStyle.Bold); 

System.Drawing.Font = new Font("Arial", 8, FontStyle.Bold);

using System.Drawing;
