The figure above shows a picture created with the
default settings of Posteriser. This creates quite a 'vibrant'
image that can be quite overpowering. I allowed for up to eight
colours as I felt this would be more than most people would want
This figure uses only three colours which can give
a much better effect. Any adjacent sliders can be used to create
an image with less than eight colours with the others set to maximum
or minimum values. The image on the Posteriser main page is another
example of using fewer colours in that case five.
This figure uses all eight possible values but all
but three use the original image pixels rather than the selected
colour. If the box beside the colour swatch is ticked the original
image pixels will be used for this range.
This figure uses all eight colour ranges but only
two colours have been selected, blue and white. By doing this
it is possible to create some strange and interesting effects.
Just adjust the sliders to get an effect you like. Small changes
can have large effects.
