is there a task that can subdivide pixels? No interpolation or fancy stuff-just 1 pixel into 4, or 1 into 2 by dimensions, whatever there isThanks

The MAGNIFY task can arbitrarily scale an image and gives you a choice of interpolants. If you want a brute force method, something like BLKREP will replicate pixels so you could e.g. expand as 2x2 then use IMARITH to divide each pixel by 4 to conserve the overall flux.-Mike
