_imagedata is a string containing the raw image data. If this data

subtype will be automatically included in the Content-Type header.

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

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.
