UnsharpMaskCommand Constructor(int,int,int,UnsharpMaskCommandColorType)

Summary

Initializes a new UnsharpMaskCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public UnsharpMaskCommand( 
   int amount, 
   int radius, 
   int threshold, 
   UnsharpMaskCommandColorType colorType 
)

- (instancetype)initWithAmount:(NSInteger)amount radius:(NSInteger)radius threshold:(NSInteger)threshold colorType:(LTUnsharpMaskCommandColorType)colorType NS_DESIGNATED_INITIALIZER;

public UnsharpMaskCommand( 
   int amount, 
   int radius, 
   int threshold, 
   UnsharpMaskCommandColorType colorType 
);

public: 
UnsharpMaskCommand(  
   int amount, 
   int radius, 
   int threshold, 
   UnsharpMaskCommandColorType colorType 
)

__init__(self,amount,radius,threshold,colorType) # Overloaded constructor

Parameters

amount
Value that represents an adjustment factor. This is a percentage.

radius
Value that indicates the size of the neighborhood used for blurring each pixel of the image.

threshold
Value that indicates the threshold for modifying the original value of the pixel. If the difference in the original pixel value and the blurred pixel value is greater than the threshold value, the original pixel value will be modified.

colorType
Flag that indicates the color space in which to apply the mask.

Example

Run the UnsharpMaskCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void UnsharpMaskConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   UnsharpMaskCommand command = new UnsharpMaskCommand(200, 15, 50, UnsharpMaskCommandColorType.Rgb); 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";

   int change = command.run(image); 
   assertTrue(change != RasterImageChangedFlags.NONE);
