Factor Property

Summary

Gets or sets a value used as an amplitude factor if the Type property is Square, Square Root, or Logarithm, and is used as a frequency factor if the Type property is Sine or Cosine.

Syntax

Objective-C

C++/CLI

Java

Python

public int Factor { get; set; }

@property (nonatomic, assign) NSUInteger factor;

public int getFactor(); 
public void setFactor( 
   int intValue 
);

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

Factor # get and set (MathematicalFunctionCommand)

Property Value

Value used as an amplitude factor when squaring, taking the logarithm of or taking the square root of the color values and as a frequency factor when taking the sine or cosine of the color values. The value of the Factor property is divided internally by different amounts, according to the type of math operation being performed. These amounts are as follows:

if the Type property is set to:		then the Factor property will be divided by:
Square		10000 internally
Logarithm		10 internally
Square Root		10 internally
Sine		100 internally
Cosine		100 internally

Only positive values are accepted.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void MathematicalFunctionCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\NaturalFruits.jpg")); 
 
   // Prepare the command 
   MathematicalFunctionCommand command = new MathematicalFunctionCommand(); 
   command.Type = MathematicalFunctionCommandType.Square; 
   command.Factor = 50; 
   //Apply Square Function to this image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
