Summary

Initializes a new LocalHistogramEqualizeCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public LocalHistogramEqualizeCommand( 
   int width, 
   int height, 
   int widthExtension, 
   int heightExtension, 
   int smooth, 
   HistogramEqualizeType type 
)

- (instancetype)initWithWidth:(NSInteger)width height:(NSInteger)height widthExtension:(NSInteger)widthExtension heightExtension:(NSInteger)heightExtension smooth:(NSUInteger)smooth type:(LTHistogramEqualizeType)type NS_DESIGNATED_INITIALIZER;

public LocalHistogramEqualizeCommand( 
   int width, 
   int height, 
   int widthExtension, 
   int heightExtension, 
   int smooth, 
   HistogramEqualizeType type 
);

public: 
LocalHistogramEqualizeCommand(  
   int width, 
   int height, 
   int widthExtension, 
   int heightExtension, 
   int smooth, 
   HistogramEqualizeType type 
)

__init__(self,width,height,widthExtension,heightExtension,smooth,type) # Overloaded constructor

Parameters

width
The width of the local histogram equalizer rectangle in pixels. The width should be more than zero.

height
The height of the local histogram equalizer rectangle in pixels. The height should be more than zero.

widthExtension
The extension of the width of the local histogram equalizer rectangle, in pixels.

heightExtension
The extension of the height of the local histogram equalizer rectangle, in pixels.

smooth
Size of the area to be used when smoothing the edges between localized blocks. Possible values are between 0 and 7, but if Height is less than or equal to 7 then the maximum value for this item is Height - 1. If Smooth = 0 the edges will not be smoothed.

type
Flag that indicates which color space to equalize.

Example

Run the LocalHistogramEqualizeCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void LocalHistogramEqualizeConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   LocalHistogramEqualizeCommand command = new LocalHistogramEqualizeCommand(15, 15, 100, 100, 0, HistogramEqualizeType.Yuv); 
   // Local Histogram equalize the image. 
   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"; 
}
