Currently it is not possible in the cpp api to set the poppler-data path at runtime. This would be very useful.
No, GlobalParams must die, so it should not be exposed in any public API.
A patch to expose the customPopplerDataDir parameter would be acceptable.
Not sure I understand. Which function has a customPopplerDataDir parameter other than in GlobalParams? I'm willing to write a patch for poppler-cpp but I can't find which C api it should wrap if we don't want to call GlobalParams.
Sure, you eventually need to call globalparams internally, but that doesn't mean you need to create a class that mimics globalparams, you can perfectly have a static member in document for example. I don't have the code at hand so can't say which class makes more sense but i guess document would be a strong candidate. Does this make sense?
