EdgeDetectorCommand(
int threshold,

threshold
Threshold value used to determine which pixels are edge pixels. If the difference determined for a pixel is greater than this value, the pixel is an edge pixel. This parameter only accepts positive values.
filter
Flag that indicates which edge detection filter to apply.
Run the EdgeDetectorCommand on an image.
