Image Thumbnail
===============
You can use matplotlib to generate thumbnails from existing images.
matplotlib natively supports PNG files on the input side, and other
image types transparently if your have PIL installed
.. code-block:: default
# build thumbnails of all images in a directory

import os
import glob
import matplotlib.image as image
if len(sys.argv) != 2:
print('Usage: python %s IMAGEDIR' % __file__)

if not os.path.isdir(indir):
print('Could not find input directory "%s"' % indir)

basedir, basename = os.path.split(fname)
outfile = os.path.join(outdir, basename)
fig = image.thumbnail(fname, outfile, scale=0.15)
