DirectionEdgeStatisticalCommand Class

Example 





Members 
Detects the variation of colors in the specified direction using statistical indices. It is similar to EdgeDetectStatisticalCommand, but this command allows you to specify the direction angle. .NET support WinRT support Silverlight support
