GrayScaleExtendedCommandクラス








メンバ 
その解像度を変更することなく、グレースケールイメージに任意のimageを変換します。
オブジェクトモデル
構文
'Declaration
 
Public Class GrayScaleExtendedCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As GrayScaleExtendedCommand
public sealed class GrayScaleExtendedCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTGrayScaleExtendedCommand : LTRasterCommand

サンプル

RedFactor = 300、GreenFactor = 590とBlueFactor = 110でimageの上でGrayScaleExtendedCommandを実行します。
