Poster Paints
Posterisation effects.
Poster Paint is a posterisation or is that posterization tool? It basically takes the original pic and then applies various mod functions to the original so instead of getting a clean picture you end up with well, blocks of colour. You can affect the end result in a number of ways such as applying the effects to the inverse and more.
Please note that some of the controls have multiple purposes - the prime purpose is indicated. Also note that some of the controls will have no effect such as the X and Y if the (*) has not been set to on. Some of the options in the dropdowns use the X Y, or if no inverse option is set then the () will be ignored. Also note that the preview might not match the end result - especially if the setting is at less than 25% or so - to get a 99% accurate view of the end result please set the preview to 100%.
X - x coordinate. This is generally used by the spotlight (*). The spotlight applies the (*) factor to the current effect. By setting it to 0,0 the effect will be strongest in the top left corner - as you move the settings the spotlight will change position. Once the spotlight is past the edge of the picture the spotlight will just get brighter and brighter until it either obliterates the picture or completely darkens the picture (in most cases).
Y - y coordinate

Combo 5 - Direction of the effect (not available under all options)
Combo 6 - Used by if R is greater than R> setting, as for other channels - the options include use the inverse () setting or use 0 (black) etc. for the channel for all pixels with values less than the threshold. If set to -1 then no pixels fit this criteria so the effect is applied normally - if the pixel is less than the current value the combo 5 effect is applied.
