title: Python3 - Change visibility of PSD layers programmatically
body: <p>Is possible to programmatically change PSD layer visibility in a PSD, without use Photoshop?</p>
  
  <p>I did check various implementation of PSD libraries for Python, but the best they do is to return the visibility value (like <code>psd_tools</code>); but the visible property is read only, so I can't change it.</p>
  
  <p>I wish there was a way to be able to extract and manipulate groups and layers in PSD files, directly from Python; but the best I can do is to use psd_tools to retrieve layers and stack them together; after export them as PNG; although this is not ideal</p>
