_imagedata is a string containing the raw image data. If this data
|
|||
|
|
can be decoded by the standard Python `imghdr' module, then the
|
|||
|
|
subtype will be automatically included in the Content-Type: header.
|

Otherwise, you can specify the specific image subtype via the _minor

parameter.

_encoder is a function which will perform the actual encoding for
|
|||
|
|
transport of the image data. It takes one argument, which is this
|
|||
|
|
Image instance. It should use get_payload() and set_payload() to
|
|||
|
|
change the payload to the encoded form. It should also add any
|
|||
|
|
Content-Transfer-Encoding: or other headers to the message as
|
|||
|
|
necessary. The default encoding is Base64.
|
|||
|
|
|
|||
|
|
Any additional keyword arguments are passed to the base class
|
|||
|
|
constructor, which turns them into parameters on the Content-Type:
|
|||
|
|
header.
