I expect that this will work, but I can’t do this: [quote='847405021, Pavel, /thread/847405, /profile/Pavel'] could you please confirm if the specific PDF-handling subset of CoreGraphics … is completely session-independent, memory-safe, and daemon-safe … ? [/quote] The problem here is one of layering. Because these APIs exist within Core Graphics it easy for them to become accidentally bound to the window server [1]. So, even if that’s not the case right now, it’s hard for us to guarantee that the implementation won’t change in the future. But there’s a trade-off here. There is no lower-level PDF API, so the alternatives are to use CG or bring your own PDF library. Unless your product already has such a thing, the latter will add a constant maintenance burden. So, you have to trade off between that and the potential risk of an urgent, and complex, update if CG breaks on you.
