title: looking for .net color quantizer libraries
body: <p>Are there any .net color quantization libraries out there other than <a href="https://nquant.codeplex.com/" rel="nofollow">nQuant</a>? </p>
  
  <p>I'm currently using nQuant in my program and it produces fantastically small files sizes however it has issues with grayscale gradients and gray shadows with transparency. Looking for alternatives to this library to use in my program.</p>
  
  <p>I've also used <a href="http://x128.ho.ua/color-quantizer.html" rel="nofollow">Color quantizer</a> which has a lot of flexible parameters but of course its a standalone application.</p>
  
  <p>Hoping to not have to resort to calling external executable..</p>
