Automatic Thumbnail???

[Loren]

Hi everyone,

I'm new to Nikola and have a question about thumbnails. If I want to make a gallery of Jupyter Notebooks, is there a way to have Nikola automatically make the thumbnails for the Jupyter Notebooks? Currently, we take a screenshot of each Jupyter Notebook, save it as a jpeg in the images folder, then we reference the thumbnail in the Main Gallery. Is there a way to automate this?

There is the "nbconvert" command-line tool that can convert notebooks to other formats like html or pdf.

https://nbconvert.readthedocs.io/en/latest/

From there you can use another tool to convert the pdfs to jpg. A quick Google search turns up a tool called "pdftocairo" that can do this, but there are probably many other options.

Another option would be something to automatically screenshot
webpages. We use puppeteer for this in the nikola-themes repo. You
could make a Nikola plugin to generate the screenshots automatically
(simple file_dep + code from
pkgindex_theme_demo_screenshots/take_screenshots.js), but this will
require you to run `nikola build` twice (first run would build .ipynb
and make screenshots, and the second run would update the gallery).
