pomtiles
A tiling program for making visuals with the pomological watercolor collection
Here's how it works: run pomfetch.py to fetch a bunch of pomological watercolors from Wikimedia's servers. It'll download 7500 of them into a folder called sources/. That's about 700 MB, so it might take a few minutes.
Then run pomlist.py to create a file, sources.json, that matches each source image up with an ID number. I don't package it here because you might want to add or remove images from your sources folder.
Tweak the number of frames you want in pomtiler.py, then run it to generate slide_deck.json.
Finally, run pomrender.py to render the actual tiled images that will live in imgs/. They're named in the form img###.png.
With that output, I run something like:
ffmpeg -framerate 1/12 -i img%03d.png -c:v mpeg4 -q 1 -pix_fmt yuv420p out.mp4
to generate a video with 12 seconds for each slide.
