matplotlib.animation.FileMovieWriter

class matplotlib.animation.FileMovieWriter(*args, **kwargs)

MovieWriter for writing to individual files and stitching at the end.

This must be sub-classed to be useful.

__init__(*args, **kwargs)

Methods

__init__(*args, **kwargs)
bin_path()	Returns the binary path to the commandline tool used by a specific subclass.
cleanup()
finish()
grab_frame(**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 by running the commandline tool.
saving(fig, outfile, dpi, *args, **kwargs)	Context manager to facilitate writing the movie file.
setup(fig, outfile[, dpi, frame_prefix, …])	Perform 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.

cleanup()

finish()

frame_format

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

grab_frame(**savefig_kwargs)

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.

setup(fig, outfile, dpi=None, frame_prefix='_tmp', clear_temp=True)

Perform setup for writing the movie file.

Parameters:

fig : matplotlib.figure.Figure

The figure to grab the rendered frames from.

outfile : str

The filename of the resulting movie file.

dpi : number, optional

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

frame_prefix : str, optional

The filename prefix to use for temporary files. Defaults to '_tmp'.

clear_temp : bool, optional

If the temporary files should be deleted after stitching the final result. Setting this to False can be useful for debugging. Defaults to True.
