matplotlib.animation.HTMLWriter

classmatplotlib.animation.HTMLWriter(fps=30, codec=None, bitrate=None, extra_args=None, metadata=None, embed_frames=False, default_mode='loop', embed_limit=None)[source]

Writer for JavaScript-based HTML movies.

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__(fps=30, codec=None, bitrate=None, extra_args=None, metadata=None, embed_frames=False, default_mode='loop', embed_limit=None)[source]
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__([fps, codec, bitrate, extra_args, ...])

Parameters

bin_path()

Return the binary path to the commandline tool used by a specific subclass.

cleanup()

[Deprecated]

finish()

Finish any processing for writing the movie.

grab_frame(**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(fig, outfile, dpi, *args, **kwargs)

Context manager to facilitate writing the movie file.

setup(fig, outfile, dpi[, frame_dir])

Setup for writing the movie file.

Attributes

frame_format

Format (png, jpeg, etc.) to use for saving the frames, which can be decided by the individual subclasses.

frame_size

A tuple (width, height) in pixels of a movie frame.

supported_formats

finish()[source]

Finish any processing for writing the movie.

grab_frame(**savefig_kwargs)[source]

Grab the image information from the figure and save as a movie frame.

All keyword arguments in savefig_kwargs are passed on to the savefig call that saves the figure.

classmethodisAvailable()[source]

Return whether a MovieWriter subclass is actually available.

setup(fig, outfile, dpi, frame_dir=None)[source]

Setup for writing the movie file.

Parameters
figFigure

The figure to grab the rendered frames from.

outfilestr

The filename of the resulting movie file.

dpifloat, default: fig.dpi

The dpi of the output file. This, with the figure size, controls the size in pixels of the resulting movie file.

frame_prefixstr, optional

The filename prefix to use for temporary files. If None (the default), files are written to a temporary directory which is deleted by cleanup; if not None, no temporary files are deleted.

supported_formats=['png', 'jpeg', 'tiff', 'svg']
