DirectionEdgeStatisticalCommandクラス








メンバ 
統計インデックスを用いて指定された方向で色のバリエーションを検出します。それはEdgeDetectStatisticalCommandと類似しています、しかし、このコマンドは方向角を指定することができます。

'Declaration
 
Public Class DirectionEdgeStatisticalCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As DirectionEdgeStatisticalCommand
public sealed class DirectionEdgeStatisticalCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTDirectionEdgeStatisticalCommand : LTRasterCommand
