Could you briefly comment on how one would use imagemagick to do “smart” upscaling rather than the regular type that makes a larger and blurrier picture? Or is it smart by default?

I’ve barely used it so I’m not sure what to look for to figure this out on my own.

Here are some options from the IM docs:

Be sure to scroll down to liquid rescale also.
