解説

このコマンドはドキュメントとMedical Imagingツールキットで利用できます。

詳細については、「明度とコントラストの変更」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ApplyLinearVoiLookupTableCommandを実行します。
