Hey everyone,
I'm an avid user of Photoshop and I use to also use Paintshop pro in the past, although I don't have it anymore. I recall that I was able to pixelate an image into 1 pixel cell size in those days, but now it seems that with modern software, I'm not able to do this at all.

for instance in photoshop, how can one pixelate an image to mosaic with a cell size selectable 1? It only allows 2 or above, but not 1 for some reason?

I require one pixel size pixelation to convert large images into sprites.

Thank you
