Example

C#	Copy Code
// 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);

Copy Code

// 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);

Visual Basic	Copy Code
' 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)
