title: Converting Ycbcr Image to grayscale with Aforge.net
body: <p>I'm new to Aforge.net.<br/>
  I have filtered and image with YCbCr filter with Aforge.Net</p>
  
  <pre><code>YCbCrFilter.Y = new Range(0, 1);
  YCbCrFilter.Cb = new Range(-0.1862745098039216f, 0.0294117647058824f);
  YCbCrFilter.Cr = new Range(0.0137254901960784f, 0.2254901960784314f);
  // apply the filter
  var YCbCrFilteredImage = YCbCrFilter.Apply(bitmap);
  </code></pre>
  
  <p>I need to convert the resulted image (i.e <code>YCbCrFilteredImage</code> ) to <code>Grayscale</code> image, to convert it later to black and white image.<br/>
  So how can I do the converting to grayscale?</p>
