MathematicalFunctionCommand Constructor(MathematicalFunctionCommandType,int)

Summary

Initializes a new MathematicalFunctionCommand class object with explicit parameters.

Syntax

Objective-C

C++

Java

public MathematicalFunctionCommand( 
   MathematicalFunctionCommandType type, 
   int factor 
)

Public Function New( _ 
   ByVal type As MathematicalFunctionCommandType, _ 
   ByVal factor As Integer _ 
)

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

public MathematicalFunctionCommand( 
  MathematicalFunctionCommandType type,  
  int factor 
)

public: 
MathematicalFunctionCommand(  
   MathematicalFunctionCommandType type, 
   int factor 
)

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:\LEADTOOLS21\Resources\Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Color 
 
Public Sub MathematicalFunctionConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\NaturalFruits.jpg")) 
 
   ' Prepare the command 
   Dim command As MathematicalFunctionCommand = New MathematicalFunctionCommand(MathematicalFunctionCommandType.Square, 50) 
   'Apply Square Function to this image. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\LEADTOOLS21\Resources\Images" 
End Class
