title: Corona - create regular display objects from sprite sheets?
body: <p>This is normal way of displaying an image:</p>
  
  <pre><code>local img = display.newImage("image.png");
  </code></pre>
  
  <p>But doesn't it save memory to put all your images in one large image and export from Zwoptex? There is documentation for creating animated sprites from sprite sheets, but what about just pulling a single image from a sprite sheet?</p>
  
  <pre><code>local zwoptexData = require "sheet1"
  local data = zwoptexData.getSpriteSheetData()
  //then what?
  </code></pre>
