AbstractMovieWriter
[source]¶Abstract base class for writing movies. Fundamentally, what a MovieWriter does is provide is a way to grab frames by calling grab_frame().
setup() is called to start the process and finish() is called afterwards.
This class is set up to provide for writing movie frame data to a pipe. saving() is provided as a context manager to facilitate this process as:
with moviewriter.saving(fig, outfile='myfile.mp4', dpi=100):
# Iterate over frames
moviewriter.grab_frame(**savefig_kwargs)
The use of the context manager ensures that setup() and finish() are performed as necessary.
An instance of a concrete subclass of this class can be given as the
writer
argument of Animation.save()
.

saving (self, fig, outfile, dpi, \*args, ...) |
Context manager to facilitate writing the movie file. |
setup (self, fig, outfile[, dpi]) |
Perform setup for writing the movie file. |
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.
