I „draw“ a shape, eg a rectangle, apply a rainbow-gradient and get this gradient „continuously“ .
How can i easy „segment“ this gradient in eg. just 50 steps? 
 
Lazy example (just 10 steps) of what i mean.
(Doing manually its quiet time-intensive. For a machine it should be very, very easy: Just divide a shape into some same-size segments and take the average of the color of this area.)

BTW: Is the gradient „wrong“ (taken from Serif-default-library) or is it real, that the most left „squares“ have the EXACTLY same red?
 
BTW 2: There should be 2 modes: A) is just appliying the quantize to the gradient itself (but keeping the shape, adjustment-layer... as one piece) and B) is also creating and grouping lot of new layers from each segment.(so, a "monochrome" pseudo-gradient could also use as a fast divider of a shape or adjustment....)....

(sry for delay - spontan journey;-))

 

I do not know what you mean with posterise-adjustment, but the pixel-mosaic-filter does it very well.

Thank you!

AHA  - my dictionary does not know posterize in the meaning of "tonal separation" (just "create lot of copys"). But the web knows this meaning and now me too;-)

Yeah, with posterize you get this effect, but it creates un-nice "fringes".

The pixel-filter creates nice straight edges/lines/cubes.... but its only as destructive filter available, so it rasterizes the item!

But, its oky, so often i do not need this feature and a wrong base-vector is replaced in millisecondes by another one...
