redFactor
Value that represents the percentage or weight given to the red value of each pixel in the image. Possible values are 0 to 1000.
greenFactor
Value that represents the percentage or weight given to the green value of each pixel in the image. Possible values are 0 to 1000.
blueFactor
Value that represents the percentage or weight given to the blue value of each pixel in the image. Possible values are 0 to 1000.
Initializes a new GrayScaleExtendedCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Parameters

redFactor
Value that represents the percentage or weight given to the red value of each pixel in the image. Possible values are 0 to 1000.
greenFactor
Value that represents the percentage or weight given to the green value of each pixel in the image. Possible values are 0 to 1000.
