Gradient Property

Summary

Gets or sets a user-defined two dimensional array of RasterColor structures that will hold the set of color shade gradients.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterColor[,] Gradient { get; set; }

@property (nonatomic, copy, nullable) NSArray<NSArray<LTRasterColor *> *> *gradient; // N x 256, where N is 1 for monotone, 2 for duotone and so forth

public RasterColor[][ getGradient(); 
public void setGradient( 
   RasterColor[][] rasterColor[][ 
);

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

Gradient # get and set (GrayScaleToMultitoneCommand)

Property Value

User-defined two dimensional array of RasterColor structures that will hold the set of color shade gradients. This property is used when the Distribution property is set to UserDefined.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void GrayScaleToMultitoneCommandExample() 
{ 
   // 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 
   GrayScaleToMultitoneCommand command = new GrayScaleToMultitoneCommand(); 
   command.Colors = new RasterColor[2]; 
   command.Colors[0].R = 255; 
   command.Colors[0].G = 255; 
   command.Colors[0].B = 0; 
   command.Colors[1].R = 255; 
   command.Colors[1].G = 0; 
   command.Colors[1].B = 0; 
   command.Gradient = null; 
   command.Distribution = GrayScaleToMultitoneCommandDistributionType.Linear; 
   command.Tone = GrayScaleToMultitoneCommandToneType.Duotone; 
   command.Type = GrayScaleToDuotoneCommandMixingType.ReplaceOldWithNew; 
   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:\LEADTOOLS22\Resources\Images";
