GetLinearVoiLookupTableCommandクラス








メンバ 
imageの中に保存されるLookupTableが線形であるならば、ウィンドウ中心とチャネル幅を取得します。imageの中に保存されるLookupTableが線形でないならば、コマンドは失敗します。
オブジェクトモデル
構文
'Declaration
 
Public Class GetLinearVoiLookupTableCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As GetLinearVoiLookupTableCommand
public sealed class GetLinearVoiLookupTableCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTGetLinearVoiLookupTableCommand : LTRasterCommand
public class GetLinearVoiLookupTableCommand extends RasterCommand
function Leadtools.ImageProcessing.Core.GetLinearVoiLookupTableCommand()
public ref class GetLinearVoiLookupTableCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand  
解説

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GetLinearVoiLookupTableCommandを実行します。そして、LookupTableのリニアリティーを確認して、このメソッドを用いてそのチャネル幅と中心を計算します。
