public class ColorIntensityBalanceCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class ColorIntensityBalanceCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As ColorIntensityBalanceCommand

public sealed class ColorIntensityBalanceCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTColorIntensityBalanceCommand : LTRasterCommand

public class ColorIntensityBalanceCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.ColorIntensityBalanceCommand()

public ref class ColorIntensityBalanceCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

解説

このコマンドは、imageの色をより正確であるかより様々にするために、赤いか、緑であるか、青チャネルの配布を変更します。
各々のカラーコンポーネントは、独立して扱われます。各々のコンポーネントのためのカラーレンジは、強度に基づくシャドウ、中間色とハイライトに分割されます。各々の範囲の値は、ColorIntensityBalanceCommandDataクラスを用いて違う形で調節されます。コンポーネントのためのColorIntensityBalanceCommandDataクラスの正の値はその特定のコンポーネントがより明るくなる原因になります、ところが、負の数はコンポーネントがより暗くなる原因になります。値0であると、コンポーネントは変わりません。
領域輝度オプションは、imageで輝度変更を最小にしようとします。
このコマンドは、RGBイメージだけをサポートします。それは、グレースケールイメージをサポートしません。
このコマンドは、48と64ビットカラーイメージをサポートします。48と64ビットカラーイメージのサポートは、Document／Medicalツールキットだけで利用できます。
このコマンドは、符合付きデータイメージをサポートしません。
このコマンドは、32ビットグレースケールイメージをサポートしません。
