MovieWriter
(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)[source]¶Base class for writing movies.
This is a base class for MovieWriter subclasses that write a movie frame data to a pipe. You cannot instantiate this class directly. See examples for how to use its subclasses.
Attributes
frame_format | (str) The format used in writing frame data, defaults to 'rgba' |
fig | (Figure ) The figure to capture data from. This must be provided by the sub-classes. |
Parameters: | fps : int
codec : string or None, optional
bitrate : int or None, optional
extra_args : list of strings or None, optional
metadata : Dict[str, str] or None
|

__init__
(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)[source]¶MovieWriter
Parameters: | fps : int
codec : string or None, optional
bitrate : int or None, optional
extra_args : list of strings or None, optional
metadata : Dict[str, str] or None

Methods
__init__ ([fps, codec, bitrate, extra_args, ...]) |
MovieWriter |
bin_path () |
Return the binary path to the commandline tool used by a specific subclass. |
cleanup () |
Clean-up and collect the process used to write the movie file. |
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 () |
Check to see if a MovieWriter subclass is actually available. |
saving (fig, outfile, dpi, *args, **kwargs) |
Context manager to facilitate writing the movie file. |
setup (fig, outfile[, dpi]) |
Perform setup for writing the movie file. |
Attributes
frame_size |
A tuple (width, height) in pixels of a movie frame. |
bin_path
()[source]¶Return the binary path to the commandline tool used by a specific subclass. This is a class method so that the tool can be looked for before making a particular MovieWriter subclass available.
frame_size
¶A tuple (width, height)
in pixels of a movie frame.
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
command that saves the figure.
setup
(fig, outfile, dpi=None)[source]¶Perform setup for writing the movie file.
Parameters: | fig :
outfile : str
dpi : int, optional
