public class StretchIntensityCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand
'Declaration
Public Class StretchIntensityCommand Inherits Leadtools.ImageProcessing.RasterCommand Implements Leadtools.ImageProcessing.IRasterCommand
'Usage
Dim instance As StretchIntensityCommand
public sealed class StretchIntensityCommand : Leadtools.ImageProcessing.IRasterCommand
@interface LTStretchIntensityCommand : LTRasterCommand
public class StretchIntensityCommand extends RasterCommand
function Leadtools.ImageProcessing.Color.StretchIntensityCommand()
public ref class StretchIntensityCommand : 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;
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。
imageの上でStretchIntensityCommandを実行して、明度値のその範囲を最大にします。
