R Property

Summary

Gets or sets a value that represents the real part of a complex number.

Syntax

C++/CLI

Java

Python

public double R { get; set; }

public double getR(); 
public void setR( 
   double doubleValue 
);

public: 
property double R { 
   double get(); 
   void set (    double ); 
}

R # get and set (Complex)

Property Value

Value that represents the real part of a complex number.

Example

using Leadtools; 
using Leadtools.ImageProcessing; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core;

   // Load an image

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\FourierTransform.jpg")); 
 
   // Prepare the command 
   // Resize the image to make sure the image's dimensions are power of two. 
   SizeCommand sizeCommand = new SizeCommand(256, 256, RasterSizeFlags.Bicubic);
