Posterize tool options
This slider and the input boxes with arrow-heads allow you
to set the number of levels (2-256) in each RGB channel that
the tool will use to describe the active layer. The total number
of colors is the combination of these levels. A level to 3
will give 23 = 8 colors.
The Preview checkbox makes all changes dynamically so that
they can be viewed straight away.
