NewColor Property
See Also 



Array of Leadtools.RasterColor structures that specifies an array of colors that will be mixed with the original gray values. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public Property NewColor As RasterColor()
Visual Basic (Usage)Copy Code
Dim instance As GrayScaleToDuotoneCommand
Dim value() As RasterColor
 
instance.NewColor = value
 
value = instance.NewColor
C# 
public RasterColor[] NewColor {get; set;}
C++/CLI 
public:
property array<RasterColor>^ NewColor {
   array<RasterColor>^ get();
   void set (    array<RasterColor>^ value);
}

Property Value

Array of Leadtools.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.

Example

Run the Leadtools.ImageProcessing.Color.GrayScaleToDuotoneCommand on an image.
