YStep Property

Summary

Gets or sets the step size in the Y direction (along image height), in pixels.

Syntax

Objective-C

C++/CLI

Java

Python

public int YStep { get; set; }

@property (nonatomic, assign) NSUInteger yStep;

public int getYStep(); 
public void setYStep( 
   int intValue 
);

public: 
property int YStep { 
   int get(); 
   void set (    int ); 
}

YStep # get and set (CorrelationCommand)

Property Value

Value that represents the step size in the Y direction (along image height), in pixels. For best results, use 1. This property accepts only positive values.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void CorrelationCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "clean.tif")); 
 
   // Prepare the command 
   RasterImage DstImage = image.Clone(); 
   CorrelationCommand command = new CorrelationCommand(); 
   command.CorrelationImage = DstImage; 
   command.Threshold = 70; 
   command.XStep = 1; 
   command.YStep = 1; 
   command.Points = new LeadPoint[90]; 
   //Apply the correlation filter. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS

   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
