Identicon Generator

Introduction

This is a small example of a simple identicon generator written in golang, the blog post can be found here: https://www.bartfokker.nl/posts/identicon/

go get to get the package

go get github.com/lercher/identicon

This Fork

This fork introduces more control over the png image generated, adds more contrast to the chosen color and publishes its list of set pixel coordinates.

Breaking Changes

The Name field is removed, b/c it is only converted to a string from the generator byte slice, which needs not be a string up-front.

The WriteImage method was removed and replaced by WritePNGImage with more parameters.

Added API

An identicon now publishes a slice of (X,Y) coordinates of set pixels as Pixels

Usage

import "github.com/lercher/identicon"

i := identicon.Generate([]byte("Simpson"))
// 50px per identicon pixel, i.e. 250x250 image written
// using dark colors in the byte range 0-127:
_ = i.WritePNGImage(w, 50, identicon.LightBackground(true))
log.Println(i.Pixels)
