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.

Parameters:
fpsint, default: 5

Movie frame rate (per second).

codecstr or None, default: rcParams["animation.codec"] (default: 'h264')

The codec to use.

bitrateint, default: rcParams["animation.bitrate"] (default: -1)

The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate.

extra_argslist of str or None, optional

Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use rcParams["animation.[name-of-encoder]_args"] for the builtin writers.

metadataDict[str, str], default: {}

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.

__init__(self, *args, **kwargs)
Parameters:
fpsint, default: 5

Movie frame rate (per second).

codecstr or None, default: rcParams["animation.codec"] (default: 'h264')

The codec to use.

bitrateint, default: rcParams["animation.bitrate"] (default: -1)

The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate.

extra_argslist of str or None, optional

Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use rcParams["animation.[name-of-encoder]_args"] for the builtin writers.

metadataDict[str, str], default: {}

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.

Methods

__init__(self, *args, **kwargs)
Parameters:
bin_path() Return the binary path to the commandline tool used by a specific subclass.
cleanup(self) Clean-up and collect the process used to write the movie file.
finish(self) Finish any processing for writing the movie.
grab_frame(self, **savefig_kwargs) Grab the image information from the figure and save as a movie frame.
isAvailable() Return whether a MovieWriter subclass is actually available.
saving(self, fig, outfile, dpi, *args, **kwargs) Context manager to facilitate writing the movie file.
setup(self, fig, outfile[, dpi, ...]) Setup for writing the movie file.
