I guess that recent releases of Gimp have a proper handling of Posterizing effect.
After having run Gimp Posterize on an image I found (thru Histogram) that the values are really only n, without messy values around the peaks.
I'm referring to Gimp 2.10.19 Samj's.
SamJ's somehow versioning is independent of Gimp"s versioning.
However, using my 2.10.14, if I apply Posterize to a I-8 and FP-32 versions of the same grayscale image I get the same histogram with sharp values, However, when I ask for 8 colors I only get 6 spikes...
OTOH the colorcube analysis still reports 199 (FP-32) or 198 (I-8) colors, and if I color-index the I-8 image, I get a colormap with 198 entries...
