I used to develop code for reading barcodes, and dealing with pixel aspect ratio was always annoying. It was one of those cases where 99.9% of images were square, but that tail always made for weird cases that had to be accounted for. Good times.

I need to append /s to my future silly replies I think… that said, I’ll never pooh-pooh a well thought response, so thanks for the nice write-up!

But of course – It’s just flipping around the -= operator!
