メンバ 
さまざまなサイズの点やシミを見つけて除去します。このメソッドはDocument/Medicalツールキットで利用できます。
オブジェクトモデル
構文
'Declaration
 
Public Class DotRemoveCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As DotRemoveCommand
public sealed class DotRemoveCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTDotRemoveCommand : LTRasterCommand
public class DotRemoveCommand extends RasterCommand
function Leadtools.ImageProcessing.Core.DotRemoveCommand()
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DotRemoveCommandを実行します。
