Summary

Initializes a new HistogramEqualizeCommand class object with explicit parameters.

Syntax

Objective-C

C++

Java

public HistogramEqualizeCommand( 
   HistogramEqualizeType type 
)

Public Function New( _ 
   ByVal type As HistogramEqualizeType _ 
)

- (instancetype)initWithType:(LTHistogramEqualizeType)type

public HistogramEqualizeCommand(HistogramEqualizeType type)

public: 
HistogramEqualizeCommand(  
   HistogramEqualizeType type 
)

Parameters

type
Flag that indicates which color space to equalize.

Example

Run the HistogramEqualizeCommand on an image and applies histogram equalization with YUV color space.

   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
