LetterAvatar

Gem for creating letter avatar from user's name.

Code extracted from discourse source (thanks guys!) - I needed this functionality in three projects, so here's the gem! :-)

Examples

Installation

System requirements

$ sudo apt-get install -y imagemagick

Mac OS X

$ brew install imagemagick ghostscript

Add this line to your application's Gemfile:

gem 'letter_avatar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install letter_avatar

Configuration

LetterAvatar.setup do |config|
  config.cache_base_path = 'public/system/lets' # default is 'public/system'
end

Usage

LetterAvatar.generate 'ksz2k', 200
=> "public/system/letter_avatars/2/K/87_178_230/200.png"

There's also helper for this. To use it, you need:

• in your helper (eg. ApplicationHelper) or controller:

  include LetterAvatar::AvatarHelper

• and in your view:

  letter_avatar_for('ksz2k', 200)
