I am trying to use a figure with a dark background in a presentation on Mac. I usually do this by using Edit -> Copy Figure and paste it into Preview or Keynote. However, this turns the black background into white. I know of the
requirement. It have set this option to off, it makes no difference.
How can I copy the figure just as it is, no fitting to an obscure page size, no changing colors, but preferably vectorized (screenshot being the last resort, obviously)
