savefig
Save matplotlib figures with embedded metadata for reproducibility and profit
MIT License
Remember that time where you tried to remake a figure for your paper and couldn't seem to get the same results? We've all been there. Well not anymore!
This module monkey patches the savefig command from matplotlib <http://matplotlib.org/>_ and inserts your current git commit hash into
the metadata of the saved file. Currently it supports PNG and PDF figures.

Usage
First, install the module from PyPI <https://pypi.python.org/pypi/savefig>_::
pip install savefig
or from source <https://github.com/dfm/savefig>_::
git clone https://github.com/dfm/savefig.git
cd savefig
python setup.py install
Then in all your code just add the following lines before importing matplotlib::
from savefig import monkey_patch
monkey_patch()
To read the metadata from an existing image file, run::
python -m savefig /path/to/figure.png
which will give you something like::
git-hash: 192a639c4a9eb7523e9becd23f359fd7d96e833f
git-date: 2014-03-29 21:30:27 -0400
git-author: Dan F-M
You can also get the diff between the saved commit hash and the version used to make the figure by running::
python -m savefig /path/to/figure.png --diff
