class ConvertToColoredGrayCommand(RasterCommand):
RedFactor + GreenFactor + BlueFactor must equal 1000. (Internally the values are divided by 1000).
For each pixel in the image the red, green and blue values are modified by the RedFactor, GreenFactor and BlueFactor properties, respectively. This allows the user to give more weight to one color, essentially enhancing that color, before the pixel is converted to grayscale.
For more information, refer to Introduction to Image Processing With LEADTOOLS. For more information, refer to Grayscale Images.
