CylinderCommand Constructor(Int32,CylinderCommandType)

Summary

Initializes a new CylinderCommand class object with explicit parameters.

Syntax

WinRT C#

C++

public CylinderCommand(  
   int value, 
   Leadtools.Imageprocessing.Specialeffects.CylinderCommandType type 
)

Public Function New( _ 
   ByVal value As Integer, _ 
   ByVal type As Leadtools.Imageprocessing.Specialeffects.CylinderCommandType _ 
)

public CylinderCommand(  
   int value, 
   Leadtools.Imageprocessing.Specialeffects.CylinderCommandType type 
)

function CylinderCommand(  
   value , 
   type  
)

public: 
CylinderCommand(  
   int value, 
   Leadtools.Imageprocessing.Specialeffects.CylinderCommandType type 
)

Parameters

value
Amount of stretching where:

Positive values: stretch the pixels toward the image edges depending on the type of cylinder.
Negative values: stretch the pixels toward the central line of the cylinder.
The valid range is from -100 to 100.

type
A value that indicates the cylinder shape.

Example

Run the CylinderCommand on an image.
