'Usage

Dim instance As GrayScaleToDuotoneCommand
Dim value() As RasterColor
 
instance.NewColor = value
 
value = instance.NewColor

public RasterColor[] NewColor {get; set;}

@property (nonatomic, strong, getter=getNewColor) NSMutableArray<LTRasterColor *> *newColor

public RasterColor[] getNewColor()
public void setNewColor(RasterColor[] value)

 <br/>get_NewColor();<br/>set_NewColor(value);<br/>Object.defineProperty('NewColor');

public:
property array<RasterColor>^ NewColor {
   array<RasterColor>^ get();
   void set (    array<RasterColor>^ value);
}

Property Value

Array of RasterColor structures that specifies an array of 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.

Run the GrayScaleToDuotoneCommand on an image.
