MathematicalFunctionCommand Constructor(MathematicalFunctionCommandType,int)

Summary

Initializes a new MathematicalFunctionCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public MathematicalFunctionCommand( 
   MathematicalFunctionCommandType type, 
   int factor 
)

- (instancetype)initWithType:(LTMathematicalFunctionCommandType)type factor:(NSUInteger)factor NS_DESIGNATED_INITIALIZER;

public MathematicalFunctionCommand( 
   MathematicalFunctionCommandType type, 
   int factor 
);

public: 
MathematicalFunctionCommand(  
   MathematicalFunctionCommandType type, 
   int factor 
)

__init__(self,type,factor) # Overloaded constructor

Parameters

type
Flag that indicates the function to be applied.

factor
Value that is 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 factor value is divided internally by different amounts, according to the type of the function being used. These amounts are as follows:

if the type parameter is set to:	then the factor parameter 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

Run the MathematicalFunctionCommand on an image with square function selected and factor = 50.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void MathematicalFunctionConstructorExample() 
{ 
   // 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(MathematicalFunctionCommandType.Square, 50); 
   //Apply Square Function to this image. 
   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:\LEADTOOLS22\Resources\Images"; 
}
