Get images from Notebook into an animated powerpoint slide

Problem

I need to display images from a Jupyter notebook in a presentation. The images should be on one slide and revealed one after the other, by clicking or shown automatically after a specified delay.

Copying, stacking and animating the images is cumbersome and time-consuming if there are many of them.

Solution

Theses scripts export images from a Jupyter notebook and saves them to a folder. These images are then inserted into Powerpoint presentation slide and animated to appear one after the other.

The images are stacked in the order that they appear in the Jupyter notebook.

Notes

• The pptx library does not support animations. I had to manipulate the presentation xml to apply the effects.

• Adding more than one set of images to a slide might break the presentation, since the image IDs might be shared across sets and wont be unique within the slide.

Usage

Dependencies

• Python 3
• pipenv
• pptx

To export the images from notebook to your specified directory:

if __name__ == "__main__":
    export_images("test_notebook.ipynb", output_dir="nb_images", prefix=None)

python nb_exporter.py

To insert images into a new presentation:

Effect options: on_click and after_click

if __name__ == "__main__":
    create_presentation("test.pptx", "nb_images", effect="after_click", delay=200)

python slide_maker.py
