I know I'm not the brightest bulb by any measure, but do some people really take less than at least a few minutes to come up with one-liners for problems as novel as graphical transformations to PDFs? Maybe if the presumed techie hacker / federal worker took it as an amusing challenge I could see this being done, but genuinely out of pure laziness? That's incredible if true.
It's not a novel problem. But yes, I don't think people quite appreciate how quick and easy it is for people who are in the habit of brewing up one-liners to solve simple problems to do that. I've done it here on HN for jq toy problems before, and I don't really doubt there are people similarly familiar with imagemagick.
