title: Pointcloud to image in open3d
body: <p>I want to create image out of point cloud (.ply), using open3d. I have no problem with reading and visualizing it but can't find anything on saving it as png or jpg. My code, visualizing cloud:</p>
  
  <pre><code>cloud = open3d.read_point_cloud(path)
  open3d.draw_geometries([cloud])
  </code></pre>
