title: Convert numpy.ndarray into imageio.core.util.Image
body: <p>I was trying to resize the input image using OpenCV but I am having problems converting the resized np array into the original format.</p>
  <pre><code>image = imageio.imread(filename) #&lt;class 'imageio.core.util.Image'&gt;
  image_re = cv2.resize(image, (256, 256)) #&lt;class 'numpy.ndarray'&gt;
  #convert into &lt;class 'imageio.core.util.Image'&gt; here
  </code></pre>
  <p>Thanks in advance.</p>
