hstack_image_arrays function¶

hstack_image_arrays(
    a,
    b
)

Stack NumPy images horizontally.

save_animation function¶

save_animation(
    fname,
    index,
    plot_func,
    *args,
    delta=None,
    step=1,
    fps=3,
    writer_kwargs=None,
    show_progress=True,

    **kwargs
)

Save animation to a file.

Args

fname : str

File name.

index : iterable

Index to iterate over.

plot_func : callable

Plotting function.

Should take subset of index, *args, and **kwargs, and return either a Plotly figure, image that can be read by imageio.imread, or a NumPy array.

*args

Positional arguments passed to plot_func.

delta : int

Window size of each iteration.

step : int

Step of each iteration.

fps : int

Frames per second.

Will be translated to duration by 1000 / fps.

writer_kwargs : dict

show_progress : bool

Whether to show the progress bar.

tqdm_kwargs : dict

Keyword arguments passed to tqdm.

to_image_kwargs : dict

**kwargs

Keyword arguments passed to plot_func.

vstack_image_arrays function¶

vstack_image_arrays(
    a,
    b
)

Stack NumPy images vertically.
