# Description
Procedural generation of I Ching hexagrams using PIL and NumPy.
# Hexagrams as a Service (HaaS)
[Trigrams, too](http://cleromancer.herokuapp.com).
# Usage
First, install [`requirements`](requirements.txt) (PIL and NumPy).
A Hexagram is composed from two of the eight trigrams. Its bars are encoded as binary numbers, **from bottom to top**, using the digits from left to right.
`1` encodes a solid bar, `0` encodes a broken bar.
Pass a 6-digit iterable of `1`/`0` or `True`/`False` to generate the hexagram.
Call `dump()` to dump it to `hexagram_output/hexagram.png`. Pass an optional string to `dump()` to control the output filename.
Call `dump_json()` to dump it to `hexagram.json`. Pass an optional string to `dump_json()` to control the output filename.
Trigrams can be constructed and dumped in the same way; pass a 3-digit iterable.
``` python
from hexagram import Hexagram, Trigram
from hexagrams import hexagrams, trigrams
for k, v in hexagrams.items():
h = Hexagram(v)
h.dump(k)
for k, v in trigrams.items():
t = Trigram(v)
t.dump(k)
```
