49 _audiodata is a string containing the raw audio data. If this data
50 can be decoded by the standard Python `sndhdr' module, then the
51 subtype will be automatically included in the Content-Type header.
52 Otherwise, you can specify the specific audio subtype via the

54 guessed, a TypeError is raised.
56 _encoder is a function which will perform the actual encoding for
57 transport of the image data. It takes one argument, which is this
58 Image instance. It should use get_payload() and set_payload() to
59 change the payload to the encoded form. It should also add any
60 Content-Transfer-Encoding or other headers to the message as
61 necessary. The default encoding is Base64.
