title: How to convert Bitmap to Image
body: <p>I am making a median filter, the problem is manipulating pixes are only possible in <code>Bitmap</code>. Later I want to show the result in a <code>PictureBox</code> which uses <code>Image</code>. I can't figure out a way to to solve this...Only thing I can think of is using a <code>Stream</code> but no idea how. Help will be appriciated~</p>
  
  <pre><code>private void toolStripPerformMedian_Click(object sender, EventArgs e)
  {
      var filtered = Filters.MedianFilter(new Bitmap(_activeImageFile), 3);
      var n = Image.FromStream() //How to do this?
  }
  </code></pre>
