This gem allows you to render text using BDF (Glyph Bitmap Distribution Format) fonts.
Add this line to your application's Gemfile:
gem 'ruby-bitmap-fonts'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-bitmap-fonts
This is an early alpha version, so this is the documentation:
my_string = "just a test"
font = BDF::Font.from_file("fixtures/ter-u12b.bdf")
canvas = BDF::Renderer.render(my_string, :font => font)
# => canvas.to_a now contains a 2-dimensional array with ones and
zeroes, representing the pixel values
puts canvas.to_a.map do |line|
line.map { |x| x == 1 ? "#" : " " }.join
end.join("\n")
# Prints:
#
