    Curves tool won't affect image

    ever0150

      I am trying to darken/sharpen a .PDF scan of an old blueprint drawing using the Curves tool, but the drawing only appears edited in the preview screen and reverts back to its original appearance once I hit OK. What do I need to do to get the changes to stay?
