Image Thumbnail
===============
You can use Matplotlib to generate thumbnails from existing images.
Matplotlib relies on Pillow_ for reading images, and thus supports all formats
supported by Pillow.

import matplotlib.image as image

description="Build thumbnails of all images in a directory.")

outpath = outdir / path.name
fig = image.thumbnail(path, outpath, scale=0.15)
