Syntax

Visual Basic
C#
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Shared Sub EdgeDetection( _
   ByVal page As ImGearRasterPage, _
   ByVal method As ImGearEdgeDetectionMethods _
)

'Usage
 
Dim page As ImGearRasterPage
Dim method As ImGearEdgeDetectionMethods
 
ImGearEffects.EdgeDetection(page, method)

public static void EdgeDetection( 
   ImGearRasterPage page,
   ImGearEdgeDetectionMethods method
)

public: static void EdgeDetection( 
   ImGearRasterPage* page,
   ImGearEdgeDetectionMethods method
)

public:
static void EdgeDetection( 
   ImGearRasterPage^ page,
   ImGearEdgeDetectionMethods method
)

Parameters

page: An ImageGear.Core.ImGearRasterPage class object on which the algorithm will be performed.
method: Type of edge detection method to perform.

Remarks

Method can be applied only to 8bit grayscale images with one channel.

Example

C#
Visual Basic

// Convert an image to grayscale and detect the edges in the image.
ImGearRasterProcessing.ConvertColorSpace(igRasterPage, new ImGearColorSpace(ImGearColorSpaceIDs.Gy));
ImGearEffects.EdgeDetection(igRasterPage, ImGearEdgeDetectionMethods.DIFF_RECURSIVE);

' Convert an image to grayscale and detect the edges in the image.
ImGearRasterProcessing.ConvertColorSpace(igRasterPage, New ImGearColorSpace(ImGearColorSpaceIDs.Gy))
ImGearEffects.EdgeDetection(igRasterPage, ImGearEdgeDetectionMethods.DIFF_RECURSIVE)
