Flags Property

Summary

Gets or sets flags that indicate the data to be shown and the plotting scale. You can use a bit-wise OR ( | ) to specify one flag from each group.

Syntax

Objective-C

C++/CLI

Java

Python

public FourierTransformDisplayCommandFlags Flags { get; set; }

@property (nonatomic, assign) LTFourierTransformDisplayCommandFlags flags;

public int getFlags(); 
public void setFlags( 
   int intValue 
);

public: 
property FourierTransformDisplayCommandFlags Flags { 
   FourierTransformDisplayCommandFlags get(); 
   void set (    FourierTransformDisplayCommandFlags ); 
}

Flags # get and set (FourierTransformDisplayCommand)

Property Value

Flags that indicate the data to be shown and the plotting scale. You can use a bit-wise OR ( | ) to specify one flag from each group.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void FourierTransformDisplayCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\FourierTransform.jpg")); 
 
   // Prepare the command 
   FourierTransformInformation FTArray = new FourierTransformInformation(image); 
   LeadRect rcRange = new LeadRect(0, 0, image.Width - 1, image.Height - 1); 
   DiscreteFourierTransformCommand DFTcommand = new DiscreteFourierTransformCommand(); 
   FourierTransformDisplayCommand command = new FourierTransformDisplayCommand(); 
 
   DFTcommand.FourierTransformInformation = FTArray; 
   DFTcommand.Range = rcRange; 
   DFTcommand.Flags = DiscreteFourierTransformCommandFlags.DiscreteFourierTransform | 
      DiscreteFourierTransformCommandFlags.Gray | 
      DiscreteFourierTransformCommandFlags.Range | 
      DiscreteFourierTransformCommandFlags.InsideX | 
      DiscreteFourierTransformCommandFlags.InsideY; 
   // apply DFT 
   DFTcommand.Run(image); 
 
   command.Flags = FourierTransformDisplayCommandFlags.Log | FourierTransformDisplayCommandFlags.Magnitude; 
   command.FourierTransformInformation = FTArray; 
   //plot frequency magnitude. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
