DigitalSubtractCommandクラス








メンバ 
2つのイメージの違いを示すために、マスク画像からライブ画像を減算します。
オブジェクトモデル
構文
'Declaration
 
Public Class DigitalSubtractCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As DigitalSubtractCommand
public sealed class DigitalSubtractCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTDigitalSubtractCommand : LTRasterCommand
public class DigitalSubtractCommand extends RasterCommand
function Leadtools.ImageProcessing.Core.DigitalSubtractCommand()
