public class GammaCorrectExtendedCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand
'Declaration
Public Class GammaCorrectExtendedCommand Inherits Leadtools.ImageProcessing.RasterCommand Implements Leadtools.ImageProcessing.IRasterCommand
'Usage
Dim instance As GammaCorrectExtendedCommand
public sealed class GammaCorrectExtendedCommand : Leadtools.ImageProcessing.IRasterCommand
@interface LTGammaCorrectExtendedCommand : LTRasterCommand
public class GammaCorrectExtendedCommand extends RasterCommand

public ref class GammaCorrectExtendedCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand
画像にLUTがあり画像データ上で作業する場合は、RasterImage.UseLookupTableをFalseに設定します。メソッドを呼び出した後で、以下のようにUselookupTableプロパティをTrueにリセットします。
rasterImage.UseLookupTable = false; Method(rasterImage); rasterImage.UseLookupTable = true;
imageの上でGammaCorrectExtendedCommandを実行します。
