SizeCommandクラス








メンバ 
新しい幅と高さにimageの大きさを変更します。
オブジェクトモデル
構文
public class SizeCommand : RasterCommand, IRasterCommand  
'Declaration
 
Public Class SizeCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
'Usage
 
Dim instance As SizeCommand
public sealed class SizeCommand : IRasterCommand  
@interface LTSizeCommand : LTRasterCommand
public class SizeCommand extends RasterCommand
function Leadtools.ImageProcessing.SizeCommand()
public ref class SizeCommand : public RasterCommand, IRasterCommand  
解説

このコマンドは、実行されたメソッドに渡されるimageの大きさを変更します。オリジナルのサイズimageを保持して、新しい大きさを変更されたバージョンを作成したいならば、ResizeCommandを使います。

詳細については、「LEADTOOLSによる画像処理入門」を参照してください。

サンプル

このサンプルは、ディスクにそれを保存する前に、サムネイルサイズにimageを変換します。
