Identigo

Identigo is a simple Go function for creating two-color identicons from a given Bytestring. It's based on Aaron Lasseigne's Clojure program (https://gist.github.com/AaronLasseigne/6255278) with some modifications.

Usage

Identigo takes the following inputs:

1. bytestring - ([]Byte) Bytestream of input data
2. tilesPerSide - (Int) of number tile resolution per rectangle side
3. multiplier - (Int) To make a large icon the function multiplies the tilesPerSide with the multiplier and scales the rendering accordingly
4. Background Color - (string) Supported colors are given below
5. Foreground Color - (string) Supported colors are given below

It returns an image object of the size (tilesPerSide * multiplier)

Supported Colors

black navy blue green teal lime aqua maroon purple olive gray silver red fuchsia yellow white
