title: initializing a 48bpp bitmap from a file in c#
body: <p>I write a 48bppRgb to a file but when I create a bitmap from this file it is 32bppArgb(object img2 has a property PixelFormat.32bppArgb).</p>
  
  <p>Minimized example:</p>
  
  <pre><code>Bitmap img1 = new Bitmap(100, 100, PixelFormat.Format48bppRgb);
  img1.Save("/img1.bmp");
  Bitmap img2 = new Bitmap("/img1.bmp");
  </code></pre>
  
  <p>Why?</p>
