Posterize effect
This function applies poster effect to the current image by quantizing the image's colors to a specified number of color levels per plane. The following dialog allows you to adjust the levels. For example, two levels means two of red, two of green, and two of blue. You can see the result (the whole image or part of image at full size) instantly from the preview window.
The following shows some results using different levels.
levels=4
levels=16
You can limit the effect to the selected region. First select the region using the selection tool and then apply this function. One example is shown here.
levels=4
