plt.show()

%%capture_img  --path "foo.jpg bar.jpg" --compression 50
plt.plot([1,2],[10,20], color = "r")
plt.show()

Changelog

0.0.8 (work in progress)

0.0.7

• Add relative path support and automatically create paths if they don't exist yet.

Add some experimental magic, but this will likely be removed in future versions:

• • experimental_capture_video_first_last captures video and extracts first and last frame from it. Useful for post-processing of videos in other video editors. Needs ffmpeg installed

• experimental_video_thumbnail extracts video from the Jupyter cell output, and replaces it with an image thumbnail of the video -> useful for Version control. Needs matplotlib and ffmpeg installed
