title: how to save a map section in Python using folium
body: <p>I am using folium to generate a map.</p>
  <pre><code>m = folium.Map(
      location=[47.842167, -120.101655],
      zoom_start=8,
      tiles='Stamen Toner'
  )
  points = (47.842167, -120.101655), (46.835627, -118.26239)
  folium.Rectangle(bounds=points, color='#ff7800', fill=True, fill_color='#ffff00', fill_opacity=0.2).add_to(m)
  
  m
  </code></pre>
  <p>I would like to save just the part that is in the rectangle..</p>
