Identicon

A Ruby library that generates GitHub-like identicons

Installing

That's easy! Use RubyGems!

Insert Identicon on your application's Gemfile:

    gem 'identicon'

and run

$ bundle

or manually install it typing

$ gem install identicon

and hitting return with your favourite finger.

Using

Require it as always

    require 'identicon'

Now you can use it through two methods: data_url_for or file_for. Simple like that.

data_url_for

This generates a data-url, so you can use it immediately, check it out:

    Identicon.data_url_for "Whatever you want!"

You can also specify a image size and a background color:

    Identicon.data_url_for "Whatever you want!", 128, [255, 255, 255]

This creates a 128x128px image, with a nice white background.

– But Vito, I want to save it as a file.
– No problemo! fil_for is the way to go.

file_for

This generates and writes the result to a file. It's as easy as just making a data-url. Check it out:

    Identicon.file_for "User's email? Username? Telephone?", "/path/to/the/image"

And, as you may guess, it also takes those optional parameters.

    Identicon.file_for "User's email? Username? Telephone?", "/path/to/the/image", 128, [255, 255, 255]
