title: Why does DrawString look so crappy?
body: <p>I am trying to add a text scale to a color image.
  The agcScale.jpg image (below) is 2 winform labels on the top and bottom and 2 winform pictureboxes on the left and right.
  The exact same code was used to produce the strings in the right and left pictureboxes, the only difference is that pictureBoxAgcVscale contains only the strings. 
  Why does DrawString in pictureBoxAgc look fine but DrawString in pictureBoxAgcVscale look so bad? I can probably fix pictureBoxAgcVscale by doing a bmp.SetPixel for each pixel but that seems like the wrong way to fix this.</p>

  <pre><code>private void DisplayAgcVscale(double min, double max)
  {
      var bmp = new Bitmap(pictureBoxAgcVscale.Width, pictureBoxAgcVscale.Height);
      var c = (max - min) / bmp.Height;
      using (var g = Graphics.FromImage(bmp))
      {
          var font = new Font("Microsoft Sans Serif", 8.25F);
          var y1 = bmp.Height / 10;
          for (var y = y1; y &lt; bmp.Height; y += y1)
          {
              var agc = y * c + min;
              var text = agc.ToString("#0.000V");
              var h = bmp.Height - y - font.Height / 2;
              g.DrawString(text, font, Brushes.Black, 0, h);
          }
      }
      pictureBoxAgcVscale.Image = bmp;
  }
