matplotlib.animation.ImageMagickWriter

class matplotlib.animation.ImageMagickWriter(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None) [source]

Pipe-based animated gif.

Frames are streamed directly to ImageMagick via a pipe and written in a single pass.

Parameters:

Parameters:	`fps : int` Framerate for movie. `codec : string or None, optional` The codec to use. If `None` (the default) the `animation.codec` rcParam is used. `bitrate : int or None, optional` The bitrate for the saved movie file, which is one way to control the output file size and quality. The default value is `None`, which uses the `animation.bitrate` rcParam. A value of -1 implies that the bitrate should be determined automatically by the underlying utility. `extra_args : list of strings or None, optional` A list of extra string arguments to be passed to the underlying movie utility. The default is `None`, which passes the additional arguments in the `animation.extra_args` rcParam. `metadata : Dict[str, str] or None` A dictionary of keys and values for metadata to include in the output file. Some keys that may be of use include: title, artist, genre, subject, copyright, srcform, comment.
