[gexiv2] How to read metadata of byte array or file object

[Stefan Krastanov <stefan krastanov yale edu>]

Hello,

Is it possible to read the metadata of a jpeg file without having a
filesystem path? For instance if I only have an opened file object
(temporary file without a name) or if I have a byte array (file
returned from a large object storage database).

I am aware of NamedTemporaryFile, but that would be an ugly (and slow) solution.

Thanks for the nice library.
Stefan
