If the ``hachoir3`` package (``hachoir`` module) is installed,
it will be used to determine metadata from audio and video files.
If the `pillow` package is installed and you are sending a photo,
it will be resized to fit within the maximum dimensions allowed
by Telegram to avoid ``errors.PhotoInvalidDimensionsError``. This
cannot be done if you are sending :tl:`InputFile`, however.
Returns:
The `telethon.tl.custom.message.Message` (or messages) containing
the sent file, or messages if a list of them was passed.
