Mosaiq

Mosaiq creates images with randomly colored pixels.

Add this line to your application's Gemfile:

gem 'mosaiq'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mosaiq

Base usage:

image = Mosaiq::Image.new(width: 3, height: 4, palette: %w[red green blue])

• Unit of width and height is pixels
• palette is an Array of color names. Any valid HTML color will work. There are also predefined Palettes.

Currently only SVG is supported.

puts image.svg.raw
# => <?xml version="1.0" encoding="UTF-8"?> ...

which looks like this when saved to a file

Result

There are three predefined Palettes:

Palette	Example	Result
black_and_white	Mosaiq::Image.new(width: 10, height: 5, palette: Mosaiq::Palette::black_and_white)
grays	Mosaiq::Image.new(width: 10, height: 5, palette: Mosaiq::Palette::grays)
random_colors(n)	Mosaiq::Image.new(width: 10, height: 5, palette: Mosaiq::Palette::random_colors(8))
