NewColor Property

Summary

Array of RasterColor structures that specifies an array of colors that will be mixed with the original gray values.

Syntax

Objective-C

C++

Java

public RasterColor[] NewColor { get; set; }

Public Property NewColor As RasterColor()

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

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

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

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.

Example

Run the GrayScaleToDuotoneCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void NewColorPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   RasterColor[] array = new RasterColor[256]; 
   for (int i = 0; i < 256; i++) 
      array[i] = new RasterColor(255, (byte)(i / 4), (byte)(i)); 
 
   //Apply duotone conversion. 
   GrayScaleToDuotoneCommand command = new GrayScaleToDuotoneCommand(); 
   command.Run(image); 
   command.Type = GrayScaleToDuotoneCommandMixingType.ReplaceOldWithNew; 
   command.NewColor = array; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS21\Resources\Images"; 
}

   Dim codecs As New RasterCodecs()

   Dim array() As RasterColor 
   Dim i As Integer

   For i = 0 To 255 
      array(i) = New RasterColor(255, CType(i / 4, Byte), CType(i, Byte)) 
   Next 
 
   'Apply duotone conversion. 
   command.Type = GrayScaleToDuotoneCommandMixingType.ReplaceOldWithNew
