title: How do I use .Node files in my Application
body: <p>I want to use <a href="https://github.com/EyalAr/lwip" rel="nofollow" title="lwip">lwip</a> in my node application. But when I tried <code>npm install lwip</code>, it failed on in my environment. So, I followed instructions on the github page, I have the project built for my environment. The output of which is three .Node files: lwip_decoder, lwip_encoder, and lwip_image. how do I use these within my application?</p>
  
  <p>I have this but I keep getting an error that .open is undefined</p>
  
  <pre><code>var lwip = require('../../custom_modules/lwip_image');
  var img = req.files.image;
  var imgPath = path.join(__dirname, '../../public/images', img.name);
  lwip.open(imgPath, function (err, image) {
      if (!err) {
          console.log(image.width);
          consoel.log(image.height);
      } else {
          console.log(err);
          console.log(imgPath);
      }
  });
  </code></pre>
