    Ah, well done!

    Reminded me of the time I finally got some scans of old Belgian comics and they had diagonal stripes all through them, a common artifact of scanning at the time.

    The answer was using imagemagick and fast Fourrier transforms to isolate the stripes and filter them out! Led me down an awesome rabbithole of math and digital imaging I still haven’t recovered from.

        Uh… scripts? Each image is unique, so that isn’t really feasible… You can go read how to do it yourself here, if you like.

        If it was that common for a time…

        Don’t really know what you’re getting at here.
