title: How to access GDI+ Effect Classes in C#
body: <p>I try to find out, how to access the Effect-Class and it's decendants of GDI+ in C#. 
  Especially, I'm interested in these:</p>
  
  <pre><code>* Blur
  * Sharpen
  * Tint
  * RedEyeCorrection
  * ColorMatrixEffect
  * ColorLUT
  * BrightnessContrast
  * HueSaturationLightness
  * ColorBalance
  * Levels
  * ColorCurve
  </code></pre>
  
  <p>Can anybody give me a hint, how to access them in C#? I even can't find them in the .net documentation. Do I have to access the gdilus.dll directory?</p>
  
  <p>Ciao!</p>
