matplotlib.animation.ImageMagickFileWriter

class matplotlib.animation.ImageMagickFileWriter(*args, **kwargs) [source]

File-based animated gif writer.

Frames are written to temporary files on disk and then stitched together at the end.

__init__(self, *args, **kwargs)

MovieWriter

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.
