Hello all,
The comments for `FPDF_LoadMemDocument` and `FPDF_LoadMemDocument64` state the following:
The memory buffer must remain valid when the document is open.
Is this comment accurate? My understanding is that I am expected to not delete the pointer passed to the first parameter of the aforementioned functions.
Suppose the above is accurate, is there a reason why this is necessary, whereas ` FPDF_LoadDocument` and ` FPDF_CreateNewDocument` are able to manage memory on their own? I am just looking to trim down memory usage where possible.
Cheers,

Yes, this is accurate. The document may be loaded lazily.

Yes, this is an absolutely binding requirement, and violating it would lead to corrupted results and/or a segfault. I've already had my experiences with that.
