NBAnim

NBAnim is a Python utility designed to display image sequences as animations within a Jupyter Notebook. It provides a simple interface to control the playback of image sequences, including play, pause, stop, and adjust the animation speed, making it ideal for visual demonstrations and presentations.

Features

• Play, pause, and stop animations.
• Navigate through image frames with next and previous controls.
• Adjust animation speed dynamically.
• Easy integration with Jupyter Notebooks.

Installation

NBAnim can be installed using pip, by cloning the repository, or directly from GitHub. Below are instructions for each method:

Using pip

To install NBAnim directly using pip, execute the following command in your terminal:

pip install nbanim

Cloning the Repository

If you prefer to install NBAnim by cloning the repository, first ensure you have git installed on your system. Then, run the following command:

git clone https://github.com/syedhamidali/nbanim.git
cd nbanim
pip install .

This will clone the repository to your local machine and install it using pip.

Directly from GitHub

You can also install the latest version of NBAnim directly from GitHub using pip:

pip install git+https://github.com/syedhamidali/nbanim.git

This method is useful if you want to install the very latest version that may include changes not yet published to PyPI.

Requirements

NBAnim requires the following to run:

• Python 3.6+
• IPython
• ipywidgets

Please make sure you have these requirements installed before installing NBAnim.

Example Usage 1

Here is a simple example of how to use NBAnim to display an animation in a Jupyter Notebook:

from nbanim import NBAnim

# List of image file paths for the frames of your animation
frames = ['path/to/frame1.png', 'path/to/frame2.png', 'path/to/frame3.png']

# Create an instance of NBAnim with the frames and optionally set the animation speed
anim = NBAnim(frames, animation_speed=0.5)

Example Usage 2

import glob
from nbanim import NBAnim

# List of image file paths for the frames of your animation
frames = sorted(glob.glob("~/Downloads/*png"))

# Create an instance of NBAnim with the frames and optionally set the animation speed
anim = NBAnim(frames, animation_speed=0.5)

The animation controls will be displayed automatically in the Jupyter Notebook

In this example, replace 'path/to/frame1.png', 'path/to/frame2.png', and 'path/to/frame3.png' with the actual paths to your image files. The NBAnim class takes care of displaying the images and providing a user interface for controlling the animation directly within the notebook.
