• This class remaps the pixel values of the image across the full range of available pixel values, in order to achieve the values passed in LowerAverage, Average and UpperAverage. For example, call this method for a grayscale image, with Average containing 150, LowerAverage containing 100 and UpperAverage containing 190. The pixels of the image will be remapped so that the new average pixel value for the entire image will be 150, the new average value for those pixels with a value between 0 and the average value for the entire image will be 100, and the new average value for those pixels with a value between the average value for the entire image and the maximum pixel value in the image will be 190.
• This command does not support signed data images.
• For an example, see the following figure:
  
  
• The following figure shows the same image, after the effect has been applied:
  
  
• To obtain this effect, the following settings were used with the method: LowerAverage = 100
  Average = 255
  UpperAverage = 255
  Type = LightControlCommandBitmapEffectsType.Yuv
