matplotlib.animation.HTMLWriter — Matplotlib 3.10.3 documentation

matplotlib.animation.HTMLWriter#
class matplotlib.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. These arguments are passed last to the encoder, just before the filename. 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. These arguments are passed last to the encoder, just before the filename. 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

Attributes

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. However, several keyword arguments that are supported by savefig may not be passed as they are controlled by the MovieWriter:

  • dpi, bbox_inches: These may not be passed because each frame of the

    animation much be exactly the same size in pixels.

  • format: This is controlled by the MovieWriter.

classmethod isAvailable()[source]#

Return whether a MovieWriter subclass is actually available.

setup(fig, outfile, dpi=None, 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 finish; if not None, no temporary files are deleted.

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