title: inDither = true Android
body: <p>Could someone explain what is really happening when setting <strong>inDither = true</strong> in the context of configarating a bitmap in Android?</p>
  
  <p>At Developer.Android one can read about the static variable </p>
  
  <pre><code>Config.RGB_565
  </code></pre>
  
  <p><em>This configuration can produce slight visual artifacts depending on the configuration of the source. For instance, without dithering, the result might show a greenish tint. To get better results dithering should be applied</em> </p>
  
  <p>I had this problem until I followed this recommendation, that is:</p>
  
  <pre><code>options.inPreferredConfig = Config.RGB_565;
  options.inDither = true;
  </code></pre>
  
  <p>So my question: how do one understand inDither in Android. Its one thing to know <strong>when</strong> to use a syntax ... another to fully understand it.</p>
  
  <p>Thanks in advance!</p>
