Java

Python

public ColorThresholdCommand( 
   ColorThresholdCommandType type, 
   ColorThresholdCommandComponent[] components 
)

- (instancetype)initWithType:(LTColorThresholdCommandType)type components:(NSArray<LTColorThresholdCommandComponent *> *)components NS_DESIGNATED_INITIALIZER;

public ColorThresholdCommand( 
   ColorThresholdCommandType type, 
   ColorThresholdCommandComponent[] components 
);

ColorThresholdCommand(  
   ColorThresholdCommandType type, 
   array<ColorThresholdCommandComponent^>^ components 
)

__init__(self,type,components) # Overloaded constructor

Parameters

type
Value that represents the color space on which the threshold is based.

components
Array of 3 ColorThresholdCommandComponent classes that contains the properties used to compare and modify each component.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ColorThresholdCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   ColorThresholdCommandComponent[] Components = new ColorThresholdCommandComponent[3]; 
 
   Components[0] = new ColorThresholdCommandComponent(); 
   Components[0].MinimumRange = 128; 
   Components[0].MaximumRange = 255; 
   Components[0].Flags = 0; 
   Components[1] = new ColorThresholdCommandComponent(); 
   Components[1].MinimumRange = 128; 
   Components[1].MaximumRange = 255; 
   Components[1].Flags = 0; 
   Components[2] = new ColorThresholdCommandComponent(); 
   Components[2].MinimumRange = 128; 
   Components[2].MaximumRange = 255; 
   Components[2].Flags = 0; 
 
   ColorThresholdCommand command = new ColorThresholdCommand(ColorThresholdCommandType.Rgb, Components); 
   //Apply color Threshold effect on the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS
