title: GDI+ Bitmap Save problem
body: <pre><code>Bitmap bff(L"1.jpg");
  bff.Save(L"2.jpg", &amp;Gdiplus::ImageFormatJPEG, NULL);
  </code></pre>
  
  <p>This creates a new file 2.jpg with zero-bytes length. 
  Isn't it supposed to write an image file that is identical to 1.jpg?</p>
  
  <p>Why I'm having zero-bytes length files? 
  I'm doing this test because writing other Bitmaps to files, result in the same output.</p>
