Posterize Levels

  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.

Preview

  The Preview checkbox makes all changes dynamically so that they can be viewed straight away.
