構文
'Declaration
 
Public Class SmoothCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As SmoothCommand

解説
詳細については、「1ビット画像のクリーンアップ」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SmoothCommandを実行します。
