matplotlib.animation.PillowWriter

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

Parameters:

fpsint Framerate for movie. codecstr or None, optional The codec to use. If None (the default) rcParams["animation.codec"] (default: 'h264') is used. bitrateint 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 rcParams["animation.bitrate"] (default: -1). A value of -1 implies that the bitrate should be determined automatically by the underlying utility. extra_argslist of str 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 rcParams["animation.extra_args"]. metadataDict[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.

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()	Check to see if 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])	Perform setup for writing the movie file.

Attributes

frame_size

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

finish(self) [source]

Finish any processing for writing the movie.

grab_frame(self, **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 command that saves the figure.

classmethod isAvailable() [source]

Check to see if a MovieWriter subclass is actually available.

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

Perform setup for writing the movie file.

Parameters:	figFigure The figure object that contains the information for frames outfilestr The filename of the resulting movie file dpiint, optional The DPI (or resolution) for the file. This controls the size in pixels of the resulting movie file. Default is fig.dpi.
