Posterize effect
The Posterize effect posterizes colors; the number of colors is reduced and gradual color transitions are replaced by abrupt color transitions. You
specify the number of tonal levels (or brightness values) for each channel in an image. The Posterize effect then maps pixels to the closest
matching level. For example, choosing two tonal levels in an RGB image gives you two tones for red, two tones for green, and two tones for blue.
Values range from 2 to 255.
The number of tonal levels for each channel.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.

Roughen Edges effect
The Roughen Edges effect makes an alpha channel rough and can add color to simulate rust and other kinds of corrosion. This effect gives
rasterized text or graphics a naturally rough look, like the look of old typewriter text.
This effect works with 8-bpc color.

What kind of roughening to use.
The color to apply to the edge for Rusty Color or Roughen Color, or to the fill for Photocopy Color.
How far, in pixels, the effect extends inward from the edge of the alpha channel.
Low values create softer edges. High values create sharper edges.
The amount of roughening.
The scale of the fractal used to calculate the roughness.
The width or height of the fractal used to calculate the roughness.
