FxSmooth somehow changes the value of a pixel with kind of average values of the neighborhood. It usually make sense for color and greyscale images, it is not often used for black and white image. For black and white images, a pixel is either black, either white, there's no real place for averages.
Now if you still want to apply smooth and get a 1bpp image, you will have to make use of the ConvertTo1Bpp method: http://guides.gdpicture.com/content/web ... o1Bpp.html
