Do I understand correctly that it isn't possible to pixelate without massively shrinking the image too? I tried the DEMO months ago, and retried again. My only wish for this tool is if it kept the size. I did try doing the opposite: 4x exporting then using inside the program, but even so... It comes off exported with zero changes, even if I set high W/H values.
Is it on purpose, as in "only part of the demo", that this occurs? My only way around that, is to screenshot raw from the program (which works assuming the file youre trying to pixelate isnt gigantic) after modification. While inside the program, it works well. Its only when exporting that its questionable, sadly.
