'Declaration

Public Property RedirectControl As Control

属性値

スパイガラスのレンダリングを向け直すのに用いられることができる外部制御。デフォルト値は、nullです。

ImageViewerSpyGlassInteractiveModeは、ビューワでマウスの下で領域の代わりにレンダリング出力を外部制御にリダイレクトすることをサポートします。この値がフォームの上で有効なコントロールに設定されるとき、対話モードは対照ペイントイベントにサブスクライブして、このコントロールの表面に拡大鏡にコンテンツを与えます。任意のWindowsフォームは機能します：しかし、それがダブルバッファリングをサポートするため、カスタムユーザ制御またはPictureBoxコントロールは最も効率的です。
