title: Python Appium Get Image from Android ImageView
body: <p>How can I get an image from an Android ImageView using Python Appium? This image should be in PNG format.</p>
  
  <p>I want to test if an icon has the correct image and I fail to use the method <code>find_element_by_image</code> provided by Appium.</p>
  
  <p>The <code>screenshot</code> method doesn't seem to be ideal for me because it takes a screenshot instead of giving me the original image, which would contain the white background while the original image doesn't have it.</p>
