newColor
Array of RasterColor structures that specifies colors that will be mixed with the original gray values. If this parameter is set to null, the Color property must contain a valid color. Pass null when you want the command to create the array of colors, two colors when replacing both colors in a binary image, or 256 colors when using a custom array of colors.
color
Used to create an array of colors internally. This parameter is used when the NewColor structure is set to null. This parameter is ignored if the NewColor value is something other than null.
type
Enumeration that indicates whether colors will be mixed or replaced.
Run the GrayScaleToDuotoneCommand on an image.
