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,

) 

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
// 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)
