Initializes a new ConvertToColoredGrayCommand class object with explicit parameters.
Syntax
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.
- 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.
- redGrayFactor
- Additional weighting factor (percentage)
used to modify the red component in the output pixel. This value can
be negative. Possible values are -1000 to 1000.
- greenGrayFactor
- Additional weighting factor (percentage)
used to modify the green component in the output pixel. This value can
be negative. Possible values are -1000 to 1000.
- blueGrayFactor
- Additional weighting factor (percentage)
used to modify the blue component in the output pixel. This value can
be negative. Possible values are -1000 to 1000.
Example
Run the ConvertToColoredGrayCommand on an image with RedFactor = 300, GreenFactor = 590, BlueFactor = 110, RedGrayFactor = 500, GreenGrayFactor = 300, BlueGrayFactor = 200.
