Leadtools.ImageProcessing.Effects Namespace > EdgeDetectEffectCommand Class > EdgeDetectEffectCommand Constructor : EdgeDetectEffectCommand Constructor(Int32,Int32,EdgeDetectEffectCommandType)



level
Level value used to determine the brightness of the edges. Standard value is 50. Range between 1 and 100. Big values will produce bright edges.
threshold
Threshold value used to determine which pixels are going to be filtered. If the difference determined for a pixel is less than this value, the pixel is set to 0. If the difference is greater, the filter will be applied to the pixel. This parameter only accepts positive values.
type
Flag that indicates the type of edge to generate.
Initializes a new EdgeDetectEffectCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Example

Run the EdgeDetectEffectCommand on an image.
