DynamicBinaryCommand Constructor(int,int)

Summary

Initializes a new DynamicBinaryCommand class object with explicit parameters.

Syntax

Objective-C

C++

Java

public DynamicBinaryCommand( 
   int dimension, 
   int localContrast 
)

Public Function New( _ 
   ByVal dimension As Integer, _ 
   ByVal localContrast As Integer _ 
)

- (instancetype)initWithDimension:(NSUInteger)dimension 
                    localContrast:(NSUInteger)localContrast

public DynamicBinaryCommand( 
   int dimension,  
   int localContrast 
)

public: 
DynamicBinaryCommand(  
   int dimension, 
   int localContrast 
)

Parameters

dimension
Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.

localContrast
Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.

Example

Run the DynamicBinaryCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
public void DynamicBinaryConstructorExample() 
{ 
   // 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 
   DynamicBinaryCommand command = new DynamicBinaryCommand(8, 16); 
   // convert it into a black and white image without changing its bits per pixel. 
   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:\LEADTOOLS21\Resources\Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Color 
 
Public Sub DynamicBinaryConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Beauty16.jpg")) 
 
   ' Prepare the command 
   Dim command As DynamicBinaryCommand = New DynamicBinaryCommand(8, 16) 
   ' convert it into a black and white image without changing its bits per pixel. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\LEADTOOLS21\Resources\Images" 
End Class
