'Declaration
 
Public Class HolePunchRemoveCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As HolePunchRemoveCommand
public sealed class HolePunchRemoveCommand : Leadtools.ImageProcessing.IRasterCommand  
function Leadtools.ImageProcessing.Core.HolePunchRemoveCommand()
public ref class HolePunchRemoveCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand  
解説

このコマンドはドキュメント/メディカルのツールキットで利用できます。

たとえば、以下のimageは、縦線を削除しておかなければなりません:

一度imageがきれいにされたら、以下の図に示されるように、パンチャーは削除されることができます:

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。

サンプル

imageの上でHolePunchRemoveCommandを実行します。
