save(outfile, format, options)
Saves the image under the given filename. If format is omitted, the format
is determined from the filename extension, if possible. This method returns
Keyword options can be used to provide additional instructions to the
writer. If a writer doesn't recognise an option, it is silently ignored. The
available options are described later in this handbook.
You can use a file object instead of a filename. In this case, you must
always specify the format. The file object must implement the seek, tell,
and write methods, and be opened in binary mode.
