OffsetCommandクラス








メンバ 
水平に、そして、垂直に、画像データをシフトします。
オブジェクトモデル
構文
'Declaration
 
Public Class OffsetCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As OffsetCommand
public sealed class OffsetCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTOffsetCommand : LTRasterCommand
public class OffsetCommand extends RasterCommand
function Leadtools.ImageProcessing.Effects.OffsetCommand()
解説
詳細については、「アートエフェクトの適用」を参照してください。

LEADTOOLSのSilverlightバージョンにおいて、RasterImageオブジェクトのための画像データがSilverlight WriteableBitmapを用いて内部的に保存されるならば、この画像処理コマンドは失敗しますオブジェクト。詳細については、「Silverlightの画像処理コマンド限界」を参照してください。

サンプル

imageの上でOffsetCommandを実行します。
