3.1.1.5 The Intelligent Scissors
In principle the Intelligent Scissors is supposed to work by
following, as closely as possible, constant-valued color contours in
the image between subsequent points clicked by the mouse. However, at
the time of this writing, the Intelligent Scissors is a GIMP
tool that seems to be broken. Much perplexed discussion has passed
through the GIMP developers' mailing list on this tool and,
unfortunately, it seems that for the present this tool has little or
no value. Even if the tool did work, I would still rank it as a tool
of little utility.
