LineProfileCommandクラス








メンバ 
3つの配列を割り当てて、特定の行でピクセルごとにR、GとBプロファイルで更新します。
オブジェクトモデル
構文
'Declaration
 
Public Class LineProfileCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As LineProfileCommand
public sealed class LineProfileCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTLineProfileCommand : LTRasterCommand
public class LineProfileCommand extends RasterCommand
function Leadtools.ImageProcessing.Color.LineProfileCommand()
解説
詳細については、「LEADTOOLSによる画像処理入門」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LineProfileCommandを実行します。
