threshold
Delta value for detecting blank space. Starting at each edge of the image and evaluating toward the center, any change in intensity that is less than or equal to this parameter is considered blank space. Valid values are 0 to 255.
Run the AutoCropRectangleCommand on an image to get the AutoCrop rectangle.
